1.0 INTRODUCTION

!

!

The Liebert APM UPS is a transformer-free, hardware-scalable, online uninterruptible power system
with 208/120V input and 208/120V output capability. The Liebert APM can operate with either a 50
or 60Hz input and provide a matching output frequency conversion. The rack-mounted 15kVA/kW
modules allow scaling the UPS’s capacity in 15kVA increments from 15kVA to a maximum of 90kVA
in a single frame.

Optional transformers are available to add 208V Isolation or 480V or 600V input capability to the
Liebert APM in both the UPS, 90kVA/kW frame only, or the Bypass Distribution Cabinet (BDC) in
either the 45kVA/kW or the 90kVA/kW frame.

The Liebert APM UPS is a SmartAisle
approach.

The Liebert APM provides continuous, high-quality AC power to business-critical equipment, such as
telecommunications and data processing equipment. The Liebert APM supplies power free of the
disturbances and variations in voltage and frequency common to utility power, which is subject to
brownouts, blackouts, surges and sags.

The Liebert APM utilizes the latest in high-frequency, double-conversion pulse width modulation
(PWM) technology and fully digital controls to enhance its reliability and increase the ease of use.

Two frame sizes are available: 45kVA/kW and 90kVA/kW. The 45kVA/kW frame is designed to accept
internal batteries; the 90kVA/kW frame does not. The 90kVA frame is, however, designed to accept
Internal Transformers and a four-breaker bypass.

Introduction

technology, appropriate for use with the SmartAisle design

Output Voltage Adjustment

This feature allows a Liebert Customer Engineer to adjust the output voltage over a range of -5% to
+16% of nominal. This permits compensation for any IR drop when the UPS is a significant distance
from the protected load. Output voltage adjustment can optimize the UPS output voltage for loads
that operate more efficiently at a UPS output voltage different from the Liebert APM’s standard
output voltage.

1.1 Battery Maintenance

WARNING

Risk of electrical shock and high short circuit current. Can cause equipment damage, personal
injury and death.

These maintenance procedures will expose hazardous live parts. Refer servicing to properly
trained and qualified personnel working in accordance with applicable regulations as well as
with manufacturers’ specifications.

1.1.1 Battery Safety Precautions

Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized personnel away from batteries.

When replacing batteries, use the same number and type of batteries.

WARNING

Risk of electric shock, explosive reaction, hazardous chemicals and fire. Can cause equipment
damage, personal injury and death.

Lead-acid batteries contain hazardous materials. Batteries must be handled, transported and
recycled or discarded in accordance with federal, state and local regulations. Because lead is a
toxic substance, lead-acid batteries must be recycled rather than discarded.

Do not dispose of battery or batteries in a fire. The battery may explode.
Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin

and eyes. It is toxic.

WARNING

Risk of electrical shock and high short circuit current. Can cause equipment damage, personal
injury and death.

The following precautions must be observed when working on batteries:

• Remove watches, rings and other metal objects.

• Use tools with insulated handles.

• Wear rubber gloves and boots.

• Do not lay tools or metal parts on top of batteries.

• Disconnect charging source prior to connecting or disconnecting battery terminals.

• Determine whether the battery is grounded. If it is grounded, remove source of ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of
such shock will be reduced if such grounds are removed during installation and
maintenance.

Lead-acid batteries can present a risk of fire because they generate hydrogen gas. In addition, the
electrical connections must be protected against accidental short circuits which can cause sparks. The
following procedures should be followed:

• DO NOT SMOKE when near batteries.

• DO NOT cause flame or spark in battery area.

• Discharge static electricity from body before touching batteries by first touching a grounded metal
surface.

• After replacing battery jars in a battery cabinet, replace the retaining straps that hold the jars in
place on the shelves. This will limit accidental movement of the jars and connectors should the
cabinet ever need to be repositioned or relocated.

Regular maintenance of the battery module is an absolute necessity. Periodic inspections of battery
and terminal voltages, specific gravity and connection resistance should be made. Strictly follow the
procedures outlined in the battery manufacturer’s manual, available on the manufacturer’s Web site.

Valve-regulated lead-acid (sealed-cell) batteries do require periodic maintenance. Although
maintenance of electrolyte levels is not required, visual inspections and checks of battery voltage and
connection resistance should be made.

NOTICE

Risk of equipment damage. Batteries should be cleaned with a dry cloth or a cloth lightly
moistened with water. Do not use cleaners on the batteries. Solvents can make the battery
cases brittle.

Because individual battery characteristics are not identical and may change over time, the UPS
module is equipped with circuitry to equalize battery cell voltages. This circuit increases charging
voltage to maintain flooded type battery cells at full capacity.

WARNING

Risk of electric shock, explosive reaction, hazardous chemicals and fire. Can cause equipment
damage, personal injury and death.

Do not use equalize charging with valve-regulated, lead-acid batteries, such as those in
Liebert Battery Cabinets. Refer to the battery manufacturer’s manual, available on the
manufacturer’s Web site, for specific information about equalize charging.

Introduction

Matching Battery Cabinets—Optional

Although the individual battery cells are sealed (valve-regulated) and require only minimal
maintenance, the Battery Cabinets should be given a periodic inspection and electrical check. Checks
should be performed at least annually to ensure years of trouble-free service.

Voltage Records: With the Battery Cabinet DC circuit breaker closed and the connected UPS
operating, measure and record battery float voltage. With the DC circuit breaker open, measure and
record the nominal (open circuit) voltage. Both these measurements should be made across the final
positive and negative terminal lugs. Compare these values with those shown below. The recorded
nominal voltage should be no less than the value shown; while the recorded float voltage should be
within the range shown. If a discrepancy is found, contact Liebert

The battery shelf can now be pulled out. Tighten each terminal connection to the retorque value.
When replacing a battery, the terminal connections must be cleaned and tightened. Disconnect and
insulate the cables connected to the battery. Secure each battery shelf with retaining screws when
maintenance is complete.

Other DC Sources

If the UPS system uses a DC source other than a factory-supplied Matching Battery Cabinet, perform
maintenance on the DC source as recommended in the DC source manufacturer’s maintenance
manual, available on the manufacturer’s Web site.

2.0 INSTALLATION

!

This section describes the Liebert APM’s environmental requirements and mechanical considerations
that must be taken into account when planning the positioning and cabling of the UPS equipment.

Because each site is unique, this section presents a guide to general procedures and practices that
should be observed by the installing engineer, rather than step-by-step installation instructions.

WARNING

Risk of electric shock. Can cause injury, property damage and death.
Special care should be taken when working with the batteries associated with this equipment.

When connected together, the nominal battery voltage is 288VDC and is potentially lethal.

• Eye protection should be worn to prevent injury from accidental electrical arcs.

• Remove rings, watches and all metal objects.

• Only use tools with insulated handles.

• Wear rubber gloves.
If a battery leaks electrolyte or is otherwise physically damaged, it must be replaced, stored in

a container resistant to sulfuric acid and disposed of in accordance with local regulations.

If electrolyte comes into contact with skin, the affected area should be washed immediately
with large amounts of water.

Installation

NOTICE

Risk of improper installation. Can cause equipment damage.
Do not apply electrical power to the UPS equipment before the commissioning engineer

arrives at the installation site.
The UPS must be installed by a properly trained and qualified engineer in accordance with

the information contained in this chapter. All the equipment not referred to in this manual is
shipped with details of its own mechanical and electrical installation information.

NOTE

Three-phase, four-wire input power is required.

NOTE

Input power must be supplied to the Liebert APM from a properly grounded Wye or Delta
source. The Liebert APM is not for use with impedance grounded systems, corner-grounded
systems or high-leg Delta systems. For these applications, an isolation transformer must be
installed between the input power and the Liebert APM.

2.1 Initial Inspections

!

!

1. While the Liebert APM and ancillary cabinets are still on the truck, inspect the equipment and
shipping container for any signs of damage or mishandling. Do not attempt to install the system if
damage is apparent. If any damage is noted, file a damage claim with the shipping agency
immediately and contact Liebert Services at 1-800-LIEBERT to inform them of the damage claim
and the condition of the equipment.

2. Compare the contents of the shipment with the bill of lading. Report any missing items to the
carrier and your local Emerson representative immediately.

3. Check the product label on the back of front door and confirm the contents match the UPS model,
capacity and main parameters that were ordered.

2.1.1 Storing for Delayed Installation

If the equipment will not be installed immediately, it must be stored indoors where the humidity is no
higher than 90% and the temperature is no higher than 104°F (40°C). The storage area must protect
the Liebert APM from excessive moisture (see 11.2 - UPS Environmental).

CAUTION

If the UPS must remain disconnected from power for more than six (6) months, the batteries
(if so equipped) must be recharged before use. To charge the batteries, the unit must be
connected to utility power and started up—the charger operates only while the Liebert APM
is operating.

Installation

CAUTION

When batteries are installed in the UPS or are cabinet-mounted adjacent to the UPS, the
battery—not the UPS—dictates the designed maximum ambient temperature.

2.2 Preliminary Checks

2.2.1 Identification

The equipment supplied has an identification tag on the back of the main door listing the type and
size of the UPS.

2.3 UPS Location

2.3.1 Positioning the UPS

Choose a location for the UPS that offers:

• Easy connection to inputs, outputs and auxiliary equipment

• Enough space to service the UPS

• Air circulation sufficient to expel heat produced by UPS

• Protection against moisture and excessive humidity

• Protection against dust and other particulate matter

• Compliance with fire prevention regulations and practices

• Operating environment temperature of 74-80°F (23-27°C) for maximum battery efficiency

2.3.2 Environmental Considerations

!

!

Before installing the Liebert APM, verify that the UPS room satisfies the environmental conditions
stipulated in 11.2 - UPS Environmental, paying particular attention to the ambient temperature
and air exchange system.

The UPS unit should be installed in a cool, dry, clean-air environment with adequate ventilation to
keep the ambient temperature within the specified operating range 32°F to 104°F (0°C to 40°C).

For optimal UPS and battery system performance and service life, maintain the operating
temperature within the range of 74-80°F, (23-27°C).

The Liebert APM is cooled by internal fans. Cooling air enters the unit through the front of the unit
and is exhausted out the back. To permit proper air flow and prevent overheating, do NOT block or
cover the ventilation openings or blow air down onto the unit. The UPS requires 24 in. (610mm)
ventilation clearance above the unit and 12" (305mm) behind the UPS.

See Table 46 for details on heat dissipation.

Battery Location

Temperature is a major factor in determining battery life and capacity. Battery manufacturers
recommend an operating temperature of 77°F (25°C). Ambient temperatures warmer than this reduce
battery life; temperatures below this reduces battery capacityv. In a typical installation, battery
temperature should be maintained between 74°F and 80°F (23-27°C). Batteries should be placed
where there are no main heat sources or air inlets to prevent portions of batteries from being either
much warmer or much cooler than other parts of the batteries.

Installation

2.4 Considerations in Moving the Liebert APM

Ensure that the UPS weight is within the designated surface weight loading (lb./ft2 or kg/cm2) of any
handling equipment. See Table 33 for weights of various units.

The Liebert APM may be rolled on its casters for short distances only. For longer distances, move the
UPS with a forklift or similar equipment to ease the relocation and to reduce vibration.

The optional battery cabinets should be moved with a forklift or similar equipment.

WARNING

Risk of moving heavy unit. Can cause property damage, injury and death.
Ensure that any equipment that will be used to move the Liebert APM has sufficient lifting

capacity. The Liebert APM’s weight ranges from 800 to 3500 lb. (363 to 1590kg). See Table 33
for details.

The UPS presents a tipping hazard. Do not tilt the Liebert APM more than 15 degrees from
vertical.

The UPS is fitted with casters—Take care to prevent movement when unbolting the
equipment from its shipping pallet. Ensure adequate personnel and lifting equipment are
available when taking the Liebert APM off its shipping pallet.

WARNING

Risk of heavy unit tipping over while being moved. Can cause property damage, injury and
death.

The casters are strong enough for movement across even surfaces only. Casters may fail if
they are subjected to shock loading, such as being dropped or rolled over holes in the floor or
obstructions. Such failure may cause the unit to tip over, injuring personnel and damaging
the equipment.

Care must be taken when maneuvering units fitted with batteries. Keep such moves to a
minimum. For further information, see Battery Cabinet Precautions on page 3.

Final Positioning

When the equipment has been finally positioned, ensure that the adjustable stops are set so that the
UPS will remain stationary and stable (see 7.0 - Installation Drawings).

The Liebert APM and its auxiliary cabinets must be installed on a concrete or equivalent, non­resilient floor.

Liebert® APM

™

2.5 Mechanical Considerations

!

The Liebert APM is constructed with a steel frame and removable panels. Top and side panels are
secured to the chassis by screws. The doors may be opened for access to power connections bars,
auxiliary terminals blocks and power switches.

The UPS comes with an Operator Control Panel that provides basic operational status and alarm
information. The cabinet houses both the power components and the internal batteries. Cooling is
provided by internal fans. The unit sits on four casters. Adjustable stops are provided to prevent the
UPS from moving once it has been moved to its final position.

WARNING

Risk of heavy units tipping over while being moved. Can cause property damage, injury and
death.

The Liebert BDC
Improper lifting may cause the cabinets to fall, causing personal injury or death and
equipment damage.

Emerson recommends lifting the units with one of the following methods:

• Installing four eyebolts in the factory-fabricated holes, one at each corner of the unit,
attaching cables or similar strapping to the eyebolts and lifting with a suitable mechanism.

• Placing suitable straps on the Liebert BDC
the unit to be lifted.

™

and battery cabinets must be properly prepared and secured for lifting.

Installation

™

or battery cabinet. The straps must go under

2.5.1 Clearances

There are no ventilation grilles on the sides of the UPS. The sides must be accessible during
installation. After installation, the unit must have a clearance of 12 in. (305mm) in the rear to permit
adequate circulation of air exhausted from the UPS. The Top Fan option eliminates the 12" (305mm)
rear clearance requirement, but it increases the Liebert APM’s height by 7.63" (194mm).

To enable routine tightening of power terminations within the UPS, make sure there is sufficient
clearance in front of the Liebert APM to permit free passage of personnel with the door fully opened.

Leave a minimum of 24 in. (610mm) between the top of the UPS frame and the ceiling to permit
adequate air circulation above the unit. Emerson recommends against using air conditioning or other
systems that blow air onto the top of the unit.

2.5.2 Floor Installation

If the Liebert APM, Liebert BDC or battery cabinet is to be placed on a raised floor, the UPS should be
mounted on a pedestal that will support the equipment point loading. Refer to the bottom view in
Figures 49, 55 or 58 to design this pedestal.

2.5.3 Cable Entry

Cables can enter the Liebert APM, Liebert BDC and battery cabinets from the top or bottom through
removable metal plates.

Some plates have factory-punched holes and others are designed to allow the personnel to punch
holes for fitting and securing the conduit. Once the conduit holes are punched, these plates should be
reattached to the UPS. The conduit size and wiring method must be in accordance with all local,
regional and national codes and regulations, including NEC ANSI/NFPA 70.

The UPS must be accessible from the right side to allow personnel to complete the cable connections
and make necessary adjustments. After installation is complete, the Liebert APM may be serviced
from the front.

NOTE

When installing the UPS, the customer must provide a disconnect with overcurrent protection
at the output of the UPS.

11 Liebert® APM

™

2.5.4 Special Considerations for Parallel Systems

1. Consider the grounding configuration of the UPS system before finalizing module placement. For
optimal ground performance, the Liebert APM modules should be close together. See 3.2.6 -
Cabling Guidelines.

2. For optimal load-sharing performance, the UPS bypass input cables and output cables should be
approximately the same length, ±10 percent.

3. Position modules in such a way as to minimize the length of power cables and control wiring
between UPS modules and the paralleling cabinet.

Refer to 4.0 - Parallel System and LBS System Installation for further information on
installing a parallel system.

2.5.5 Special Considerations for 1+N Parallel Systems

Consider the grounding configuration of the UPS system before finalizing module placement. See

3.2.6 - Cabling Guidelines.

Emerson recommends matching the impedance in the bypass path of paralleled systems as closely as
possible.

The impedance mismatch can be minimized by controlling the wiring length of each unit. The design
and the layout of the UPS system and associated panels and cabling should be examined closely to
ensure that cable lengths and impedances are closely matched. The Liebert 1+N UPS module is
supplied with a sharing reactor to minimize the impact of cable impedance mismatch. The cabling
impedance must be carefully controlled to ensure good bypass current sharing.

Installation

For Liebert APM systems, the cabling impedances must be within 10% from maximum to minimum.
If the cabling impedances must be greater than 10%, contact your Emerson representative to
calculate whether the system will result in an overload condition when operating on bypass.

When bringing the 1+N system online for the first time or after removing one unit, Emerson
recommends checking the bypass current mismatch. To check the bypass current mismatch:

1. Place a load on the bypass of each UPS module.

2. View the output current of each unit.

The accuracy of the currents displayed on the UPS module is sufficient for this check. If the mismatch
is greater than 10%, the bypass impedances must be balanced or the load must be limited to less than
the maximum rating.

2.6 45kVA and 90kVA UPS Frames—Auxiliary Cabinets

The 45kVA frame consists of a single cabinet housing the UPS components and the internal battery
string. The 90kVA frame, also a single cabinet, does not accommodate internal batteries, but does
provide for an internal four-breaker bypass or an internal transformer. The internal transformers are
available with 480V:208V; 600V:208V; or 208V:208V isolation input primaries.

Optional battery cabinets are available for each Liebert APM model to provide extended run time.
Each battery cabinet houses a single string of batteries per cabinet that operate in parallel with the
Liebert APM’s internal batteries (45kVA frame only). The battery cabinets are designed to be bolted
to the left side of the UPS (see Figure 1). Refer to 5.4 - External Battery Cabinet Installation for
details.

Optional Liebert BDC
provide an external wraparound maintenance bypass switch for servicing the UPS.

Liebert BDCs are designed to be bolted to the right side of the UPS (see Figure 1). Refer to 6.4 -
Locating the Cabinet for further details.

™

units are available. These cabinets house the components necessary to

System Composition

A UPS system can comprise a number of equipment cabinets, depending on the system design
requirements—e.g., UPS cabinet, External Battery Cabinet and External Bypass Cabinet. All
cabinets used will be the same height and will be designed to be positioned side-by-side to form an
aesthetically appealing equipment suite.

3.0 ELECTRICAL CONNECTIONS—UPS

!

The UPS requires both power and control cabling once it has been mechanically installed. All control
cables must run separate from power cables in metal conduits or metal ducts that are electrically
bonded to the metalwork of the cabinets to which they are connected.

WARNING

Risk of electric shock. Can cause property damage, injury and death.

Before connecting input power to the Liebert APM, ensure that you are aware of the location
and operation of the overcurrent protection devices that connect the UPS input/bypass supply
to the power distribution panel.

De-energize and lockout or tagout all incoming high- and low-voltage power circuits before
installing cables or making any electrical connections.

3.1 Power Cabling

3.1.1 Cable Rating

The main factors affecting the choice and size of cable are voltage, current (also taking into account
overcurrent), room temperature and conditions of installation of the cable. Refer to ANSI/NFPA 70.

The power cables of the system must be sized with respect to the following description:

Electrical Connections—UPS

• UPS input cables - The UPS input cables must be sized for the maximum input current,
including the maximum battery recharge current, given in Table 41, with respect to the unit
rating and the input AC voltage.

• UPS bypass and output cables - The bypass and output cables must be sized for the nominal
output current, given in Table 41, with respect to the unit rating and the output AC voltage.

• Battery cables - Each UPS unit has its own internal batteries factory-wired. If connecting an
external battery cabinet, the battery cables must be sized for the battery discharge current at the
end-of-discharge voltage, as given in Table 41, with respect to the unit rating.

NOTE
Table 41 gives nominal currents for determining the size of UPS power cables. Other

important factors to consider include cable route length and coordination with protective
devices.

The power cables can be sized to suit the UPS unit rating according to Table 41.

Lug Size and Torque Requirements

Refer to Table 41 for lug size and torque requirements and to Table 18 and Figure 60.

3.2 External Protective Devices

For safety concerns, it is necessary to install external circuit breakers or other protective devices for
the input AC supply of the UPS system. This section provides generic practical information for
qualified installation engineers. The installation engineers should be knowledgeable about regulatory
wiring standards and the equipment to be installed.

To reduce the risk of fire, connect only to a circuit provided with branch circuit overcurrent protection
in accordance with NEC ANSI/NFPA 70.

15 Liebert® APM

™

3.2.1 Rectifier and Bypass Input Supply of the UPS

Overcurrents

Install suitable protective devices in the distribution unit of the incoming mains supply, considering
the power cable current-carrying capacity and overload capacity of the system. Generally, the
magnetic circuit breaker with IEC60947-2 tripping curve C (normal) at the 125% of the nominal
current listed in Table 41 is recommended.

Split bypass: In case a split bypass is used, separate protective devices should be installed for the
rectifier input and bypass input in the incoming mains distribution panel.

NOTE

The rectifier input and bypass input must use the same neutral line.

For an IT power network system, a 4-pole protective device must be installed on the external
input distribution and external output distribution of the UPS.

Earth Leakage, RCD Devices

Any residual current detector (RCD) installed upstream of the UPS input supply:

• Must be sensitive to DC unidirectional pulses (Class A)

• Must be insensitive to transient current pulses, and

• Must have an average sensitivity, adjustable between 0.3 and 1A.

To avoid false alarms, earth leakage monitoring devices when used in systems with split bypass input
or when used in paralleled UPS configurations, must be located upstream of the common neutral
sinking point. Alternatively, the device must monitor the combined four-wire rectifier and split
bypass input currents.

Electrical Connections—UPS

The residual earth current introduced by the RFI suppression filter inside the UPS is greater than

3.5mA and less than 300mA. Liebert recommends verifying the selectivity with all other differential
devices both upstream of the input distribution board and downstream (toward the load).

3.2.2 External Battery

The DC-compatible circuit breaker provides overcurrent protection for UPS system and battery,
which is provided by the external battery cabinet.

3.2.3 UPS Output

If an external distribution panel is used for load distribution, the selection of protective devices must
provide discrimination with those that are used at the input to the UPS (see Table 47).

Liebert® APM

™

16

3.2.4 UPS Input Configuration

By default, the Liebert APM ships with internal links installed between the bypass input and main
(rectifier) input (single input configuration see Figure 84).

Figure 4 shows the Liebert APM in a split bypass (single source dual-input) configuration. In this
configuration, the static bypass and the maintenance bypass lines are supplied by the same source
using separate feeds. Both feeds must be protected externally with properly sized protective devices.

To wire the Liebert APM as a single source dual-input UPS, remove the links and wire the bypass
feed to the bypass busbars, then wire the main feed to the main busbars (see Figure 8).

3.2.6 Cabling Guidelines

The following are guidelines only and are superseded by local regulations and codes of practice where
applicable. Use wiring rated at 75°C or greater.

1. Take special care when determining the size of the neutral cable, as current circulating on the
neutral cable may be greater than nominal current in the case of non-linear loads. Refer to the
values in 11.4 - UPS Electrical Characteristics.

2. The ground conductor should be sized according to such factors as the fault rating, cable lengths
and type of protection. The ground cable connecting the UPS to the main ground system must
follow the most direct route possible. Control wiring and power wiring must be run in separate
conduit. Output and input cables must be run in separate conduit.

3. Consider using paralleled smaller cables for heavy currents—this can ease installation.

4. When sizing battery cables, a maximum voltage drop of 4VDC is permissible at the current
ratings in Table 43. For terminal connection sizing, see Tables 41 through 43.

5. In most installations, the load equipment is connected to a distribution network of individually
protected busbars fed by the UPS output, rather than connected directly to the UPS itself. When
this is the case, the UPS output cables can be rated to suit the individual distribution network
demands rather than being fully load-rated.

NOTE

If more load is added to the distribution panel, the unit’s cabling must be resized.

6. When laying power cables, do not form coils; this will help avoid increasing formation of
electromagnetic interference.

3.2.10 Protective Devices

!

For safety, it is necessary to install circuit breakers in the input AC supply external to the UPS
system. Given that every installation has its own characteristics, this section provides guidelines for
qualified installation engineers with knowledge of operating practices, regulatory standards and the
equipment to be installed.

UPS Rectifier and Bypass Input Supply

Protection from excessive overcurrents and short circuits in power supply input

External overcurrent protection for the AC output circuit is to be provided. See 11.4 - UPS Elec­trical Characteristics and Table 47 for overload capacity.

A breaker is used for internal battery circuit overcurrent protection. When an external battery
supply is used, overcurrent protection for the battery circuit is to be provided by the customer.

• Dual Input Single Source

When wiring the UPS with dual inputs but with a single input source, the Rectifier input and the
Bypass input must be protected separately. Size the breakers according to the input currents
shown in Table 41.

NOTE

For single or dual input, a 120V shunt trip coil(s) is required when a breaker is supplied by the
customer. See Figures 4 and 5 for details.

Fuses

Electrical Connections—UPS

The Liebert APM’s main input and bypass input busbars are equipped with fuses (six locations; see
Figure 51). The type is Bussman 170M4465, rated at 550A and 700V.

System Output

When using an external distribution panel for load distribution, the output neutral and input neutral
must be separated at the input to the UPS.

3.2.11 Cabling Procedure

CAUTION

The operations described in this section must be performed by authorized electricians or
qualified technical personnel. If you have any difficulties, contact your local Emerson
representative or Liebert Services.

NOTE

Hydraulic pressure pliers, combinative tools and piston ring pliers should be used to connect
AC wiring.

Once the equipment has been positioned and secured for operation, and the battery and ground lugs
have been connected (see 3.2.7 - Cable Connections), connect the power cables as described below.
(Study the reference drawing in 7.0 - Installation Drawings.)

1. Verify that all incoming high and low voltage power circuits are de-energized and locked out or
tagged out before installing cables or making any electrical connections.

2. Remove the right side panel to gain easier access to the connections busbars.

3. Connect the safety ground and any easier bonding ground bus cables to the copper ground busbar
located in the middle of the Liebert APM below the Input and Bypass connections. All cabinets in
the UPS system must be connected to the user’s ground connection.

NOTE

The grounding and neutral bonding arrangement must comply with the National Electrical
Code and all applicable local codes.

8. Refit all protective covers removed for cable installation.

3.3 Control Cables Details

3.3.1 Static Bypass Assembly Features

Based on your site’s specific needs, the UPS may require auxiliary connections to manage the battery
system (external battery circuit breaker, battery temperature sensor), communicate with a personal
computer or provide alarm signaling to external devices or for Remote Emergency Power Off (REPO).
Terminations for these functions are located at the front of the static bypass module. The main
features are:

• Input and output dry contacts signal (one pair of contacts of relay)

• Emergency Power Off control (EPO)

• Environmental parameter input interface

• User communication (for data setting and user background monitor)

• Liebert IntelliSlot

• Temperature detect interface

The UPS provides input dry contacts and output dry contacts on the Auxiliary Terminal Block (ATB).

3.4.1 Input Dry Contacts

External input dry contacts are connected via the ATB. Dry contacts are available for environment
detection, battery ground fault detection, etc.

The UPS accepts external signal from zero-voltage (dry) contacts connected through external dry
contact terminals produced, and these terminals are on the static bypass assembly. Through software
programming, these signals become active when these contacts connect to +12V to ground (in the
most left side). The cables connected to the monitor board must be separated from power cables.
Moreover, these cables should be double-insulated with a typical cross-section of 0.5 to 1mm
maximum connection length between 82 and 165ft. (25-50m). The ATB has several input dry contacts.

3.4.5 EPO Input—Optional

NOTICE

Risk of exceeding internal voltage limits. Can cause equipment damage.
Do not apply more than 12V to the Emergency Power Off (EPO) input. Exceeding 12V on this

input can damage the Liebert APM’s internal circuitry and control boards. Exceeding 12V will
also put the Liebert APM in an EPO state, and the unit will not reset, making it non­functional.

The UPS has an Emergency Power Off (EPO) function operated by a button on the control panel or by
a remote contact provided by the user. The EPO button is under a hinged, clear plastic shield.

The J6 connector, shown in Figure 21, is the remote EPO input interface. The EPO has NO/NC
contacts that become active when shorting terminals J6: 3 and 4 or open terminal connection J6: 2
and 1.

If an external Emergency Stop capability is required, it is connected at terminals J6: 1 and 2 and at
J6: 3 and 4 on the monitor board. It also is connected to the Normally Open or Normally Closed
remote stop switch between these two terminals using shielded cable (see Figure 21 and Table 8). If
this function is not used, terminals J6:3 and 4 must be opened and J6:1 and 2 must be closed.

the UPS, open the upstream feeder breaker(s) when the remote EPO is activated.

NOTE

Normally Closed EPO – J6: 1, 2, these terminals are supplied factory-linked on the Bypass
Module on the UPS and must remain installed if using NO contacts.

NOTE

All auxiliary cables of terminal must be double-insulated. Wire should be 20-16AWG stranded
for maximum runs between 80 and 200 feet (25-60m), respectively.

4.0 PARALLEL SYSTEM AND LBS SYSTEM INSTALLATION

This chapter gives details on the installation of a parallel system and an LBS system.

4.1 General

A parallel Liebert APM system can consist of two Liebert APM cabinets connected in parallel without
a main system static bypass. Instead, the bypass static switches of each UPS share the load when the
system transfers to the utility bypass supply. A third-party APM paralleling switchboard may be used
to provide external maintenance capability. See Figure 23 for details.

From a power viewpoint, each module is internally identical to the single-module configuration. A
parallel system requires intermodule control signals to manage the load sharing, synchronizing and
bypass switching. The control signals are connected through parallel communication cables, which
provide bi-directional communication between the two Liebert APM units of the system. A second
parallel cable is provided to establish redundancy.

When Liebert APM units are to be connected in parallel, a sharing inductor assembly is required and
must be installed inside the Liebert APM cabinet. The inductor may be installed at the factory or
field-installed.

4.2 System Installation Procedures

The installation of a parallel UPS should follow the procedures for a single UPS module with the
additional requirements detailed in this section.

4.2.1 Preliminary Checks

Be sure that the options of the parallel cables are correct and that the modules are of the same rating,
model and with the same software and hardware release.

WARNING

To achieve coordinated operation of the modules in the parallel system, it is required to
configure each module separately using Emerson configuration software. This must be done
by Emerson service personnel.

4.2.2 Cabinet Installation

Position the UPS modules and make connections as shown in Figure 23. The output distribution
consisting of external UPS output switches and maintenance bypass must be installed, as shown in
Figure 23, to facilitate maintenance and system testing.

A dual bus system consists of two independent UPS systems, each containing one or more parallel
UPS modules, as shown in Figure 30. The dual bus system has high reliability and is suitable for
loads with multiple input terminals. For a single-input load, an optional static transfer switch can be
fitted to achieve the transfer between the two outputs of the dual bus system.

Figure 30 Typical dual bus system (with STS and LBS)

Parallel System and LBS System Installation

The dual bus system uses the LBS to keep the output of the two independent UPS systems (or parallel
systems) in synchronization. One system is designated as the master, the other is designated as the
slave. The operation modes of the parallel system comprise master and/or slave operation in normal
or bypass mode.

Place the UPS modules side by side and interconnect the UPS modules according to the following
instructions.

4.3.2 External Protective Device

Refer to 3.2 - External Protective Devices.

4.3.3 Power Cable

The power cable wiring is similar to that of the UPS module. Refer to 3.1 - Power Cabling.

5.0 BATTERY INSTALLATION

!

!

5.1 Introduction

Emerson recommends that the batteries in external cabinets be the same type and made by the same
manufacturer as the internal batteries in the Liebert APM.

If multiple sets of batteries connected in parallel are used to provide the required battery backup run
times, fit each set with an isolating device to permit working on one of the battery sets while leaving
the others in service and providing backup protection.

5.2 Safety

Special care should be taken when working with the batteries associated with the Liebert APM
system equipment.

WARNING

Risk of electrical shock and arc flash. Can cause property damage, injury and death.

The Liebert APM’s internal batteries are connected and energized even if the UPS is turned
Off. To minimize the risk of injury, a properly trained and qualified service person should
disconnect internal batteries before any maintenance is performed on the unit.

When all batteries are connected together, the battery terminal voltage may exceed 324V and
is potentially lethal.

The center of the battery is connected to the neutral of the UPS and is grounded.
A battery can present a risk of electrical shock and high short circuit current. The following

precautions should be observed when working on batteries:

• Remove watches, rings and other metal objects.

• Use tools with insulated handles.

• Wear rubber gloves and boots.

• Do not lay tools or metal parts on top of batteries.

• Disconnect charging source prior to connecting or disconnecting battery terminals.

• Determine whether the battery is grounded. If the battery is grounded, remove source of

the ground. Contact with any part of a grounded battery can result in electrical shock. The
likelihood of such shock can be reduced if such grounds are removed during installation and
maintenance.

Battery Installation

When replacing batteries, replace with batteries of the same type and manufacturer, or equivalent.
Refer to 11.2 - UPS Environmental for a list of approved batteries or contact your Emerson
representative.

Liebert® APM

CAUTION

Batteries used in the Liebert APM and its auxiliary cabinets must be of an approved type.
Replacing batteries with an incorrect type can cause an explosion and fire. Refer to Tables 38
and 40 for acceptable batteries.

Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate
batteries. Released electrolyte is harmful to the skin and eyes. It is toxic.

™

5.3 UPS Batteries—Liebert APM 45kVA Frame Only

See Figure 35

The Liebert APM’s internal batteries are fully charged before the unit is shipped. During storage and
transportation, some charge is lost. All batteries should be recharged before use. The battery charger
works only when the Liebert APM is connected to input power and turned On.

NOTE

Full safety instructions concerning the use and maintenance of UPS batteries are provided in
the appropriate battery manufacturer's manuals, available on the manufacturer’s Web site.

The battery safety information contained in this section relates to key considerations that must
be taken into account during the installation design process and might affect the design
outcome, depending on your installation.

5.3.1 Internal Battery Breaker Component Locations and Control Wiring

The Liebert APM 45kVA frame contains internal batteries. The batteries are protected by an internal
battery breaker. Figure 34 shows the component location; Figure 35 shows the control wiring.

5.4.1 Matching Battery Cabinets

A matching battery cabinet is available. Refer to Figure 37. The same model battery cabinet may be
installed in parallel in multiple cabinet strings for additional capacity. Battery run time depends on
the cabinet model, the number of cabinets and the load on the UPS.

Handling—The battery cabinet has casters to facilitate movement over short distances. The bottoms
of the battery cabinets are reinforced to permit movement by forklift over longer distances.

Inspection—Remove all panels and visually inspect the batteries, bus connections, and cabinet for
any damage. Exercise caution; voltage is present within the battery cabinet even before installation.
If there are signs of damage, do not proceed. Call Liebert Services at 1-800-542-2378.

Storage—The batteries can be stored for up to six months without appreciable deterioration. If
planning to store a battery cabinet for longer than six months or at temperatures higher than 77°F
(25°C), contact Liebert Services for recommended precautions.

The following notes, in conjunction with the diagrams (Figure 37), illustrate the broad principles to
be followed when fitting and connecting the majority of battery cabinet installations.

CAUTION

Any battery system should be installed by properly trained and qualified personnel.

When installing an external battery cabinet that is NOT a Liebert APM battery cabinet, the customer
must provide overcurrent protection. See Table 43 for sizing of protection devices.

Battery Installation

NOTE

When using an external battery supply that is not provided with the UPS, please make
reference to the battery manufacturer’s installation manual for battery installation and
maintenance instructions, available on the manufacturer’s Web site. When replacing batteries,
Emerson recommends that the batteries in external cabinets be the same type used internally in
the Liebert APM. See Tables 38 and 40 for batteries that are approved for use with the Liebert
APM.

5.4.3 Installation Considerations

Position—Liebert battery cabinets come in versions specific to the left side of the UPS. If the system
includes a matching Liebert BDC, the cabinet should be mounted to the right of the UPS (nearest the
busbars) and the battery cabinet(s) should be installed to the left of the UPS.

The battery cabinet(s) are designed to be located conveniently next to each UPS module on the left
side only and are also available in stand-alone configurations with painted side panels. The front
access design eliminates side and rear service clearance requirements. Refer to Table 36 for battery
cabinet dimensions and weights.

Bolt-On Cabinets—Matching battery cabinets are designed to bolt only onto the left side of the UPS
module cabinet. Use bolts that ship with each unit to connect cabinet frames at posts, two places in
the front and two places in the rear.

Service Clearance—Allow front access to the battery cabinet at all times for maintenance and
servicing. Electrical codes require that the battery cabinet be installed with no less than 3 feet (1m) of
clearance at the front of the cabinet when operating. Side and rear panels do not require service
clearance.

Cables—Cables may be run between the cabinets through cutouts in the top of the cabinet,
eliminating the need for external conduit runs. Route cables before moving cabinets into final position
for bolting together. No top or bottom entry cables are required, except for remotely located cabinets
which require conduits.

Software—To allow the UPS to accurately display the battery run time, the number of battery
cabinets must be noted when performing initial startup and setup using the configuration software.
This is to be performed by the Liebert Services engineer when commissioning the unit.

Casters and Adjustable Stops—The adjustable stops are not designed to bear the full weight of the
cabinet. Lower the stops until they are finger-tight in contact with the floor. Then tighten a small
amount with a wrench (less than two turns) to give a good friction fit. When mounting the battery
cabinet on seismic stands, ensure that the casters are bearing the weight of the cabinet.

Battery Installation

5.4.4 Connecting the Battery Cabinet to the UPS

After the battery cabinet equipment has been positioned and secured for operation and the batteries
have been connected, connect the power cables as described below (see Figure 40).

Notes

1. Install in accordance with national and local electrical codes.

2. Input and bypass must share the same single source.

3. UPS system input and output cables must be run in separate conduits.

4. Control wiring must be run in separate conduits.

5. Optional 54-pole, 225A for 45kVA frame only or optional 54-pole, 400A
for 90kVA frame only.

6. Transformer available: 480V or 600V input.

6.1 Normal (UPS) Mode

While the Liebert BDC is in Normal mode (MBB open; BIB/MIB closed), the UPS is supplying the
connected load with continuous, high-quality AC power. In this mode of operation, the load is
protected by the UPS.

6.2 UPS Static Bypass Mode

When the Liebert APM is in Static Bypass mode, it provides an alternate path for power to the
connected equipment. Should the UPS need to be taken out of service for limited maintenance or
repair, manual activation of the Static Bypass will cause an immediate transfer of the equipment
from the UPS inverter to the bypass source. In this mode, power will still be supplied to the UPS;
however, the load is NOT protected by the UPS.

6.3 Maintenance Mode

!

When the Liebert BDC is in Maintenance mode (MBB closed; BIB/MIB open), it provides an alternate
path for power to the connected equipment should the UPS need to be taken out of service for limited
maintenance or repair. In this mode of operation, no power is supplied to the UPS and the load is
NOT protected by the UPS.

6.4 Locating the Cabinet

This Liebert BDC may be mounted to the left of the UPS or installed as a stand-alone unit. In either
case, ensure that the unit is in a well-ventilated area and that there is clearance for access to the
switches and cable connections as required by national and local codes.

6.5 Cable Installation

6.5.1 Wiring Preparation

Be sure that the unit is not connected to any AC utility power source or UPS before installing any
wiring to this unit. This Liebert BDC should be installed by a qualified / certified electrician.

Liebert IntelliSlot® Installation

8.0 LIEBERT INTELLISLOT® INSTALLATION

8.1 Liebert IntelliSlot Communication

The Liebert APM has three Liebert IntelliSlot ports to allow installation of optional communication
cards. Liebert IntelliSlot cards communicate via Liebert’s proprietary Velocity protocol to cards that
translate the information into such protocols as SNMP and Modbus. Other cards provide dry contact
signals for external signaling of operating status.

The Liebert IntelliSlot communication ports may be installed or removed while the Liebert APM is
operating.

8.2 Liebert IntelliSlot Web Card—SNMP/HTTP Network Interface Card

This network interface card provides all real-time data and status information as SNMPv1 traps for
connection to a 10/100-baseT Ethernet connection. The same card also will transmit the same status
information and all measured parameters for display via a Web browser. The Liebert IntelliSlot bays
are on the right side of the control module and labeled as IntelliSlot1, IntelliSlot2 and IntelliSlot3.

The Liebert IntelliSlot Relay Card has five jumpers, P3 through P7, as shown in Figure 64. Each
jumper connects two pins.

Figure 64 Jumper location and numbering

Liebert IntelliSlot® Installation

By default all five jumpers have shunts installed. The two pins are shunted together to provide the
functions shown in Table 21, allowing relay commons to be tied together.

The jumpers should be removed if there is any external voltage source that may intentionally or
inadvertently be connected to the relay.

Removing the shunt from any two pins breaks the connection between the relay commons so they are
not tied together.

8.6 Alber® BDSi™ Battery Monitoring System—Optional

The matching Liebert battery cabinets allow installing an optional Alber BDSi battery monitoring
system inside the cabinet. The Alber BDSi by Emerson continuously checks all critical battery
parameters, such as cell voltage, overall string voltage, current and temperature. Automatic periodic
tests of internal resistance of each battery will verify the battery's operating integrity. Additional
capabilities include automatic internal DC resistance tests and trend analysis providing the ability to
analyze performance and aid in troubleshooting.

The Alber BDSi system is installed inside the battery cabinet as shown in Figures 11 and 12. The
monitoring system power inlet is wired to the Alber BDSi Fuse Block on the UPS (see ,Figures 13
and 66). The Alber BDSI fuse block supplies 120VAC and has an 8A fuse.

If required, power can be supplied from the output terminals of the UPS, a distribution panel or
another UPS-protected source.

For details about operating the Alber system, refer to the Alber unit’s documentation, available at

http://www.alber.com/
