1.4Operating Modes
The Liebert APS UPS is a true online double-conversion system, having the following operating
modes:
•Normal Mode
• Backup Mode
•Auto Restart Mode
• Bypass Mode
Normal Mode
The power module rectifiers derive power from a utility AC source and supply regulated DC power to
the inverter. The module’s inverter regenerates precise AC power to supply the connected equipment.
The battery charger is in the power module and maintains a float-charge on the batteries of the UPS;
additionally, the optional charger module can also charge the batteries to maintain a quicker
recharge time for long backup time applications.
Backup Mode
When AC utility fails, the connected equipment is supplied power by the inverter, which obtains
energy from the battery modules. The output power will not be interrupted during the failure or
restoration of the AC utility/mains source.
Auto Restart Mode
Product Introduction
After a power outage and complete battery discharge, and once AC utility is restored, the UPS will
automatically restart and resume supplying power to connected equipment. This feature is enabled at
the factory, but can be disabled by the user. The user can also program two auto restart delay settings
from the LCD:
• Battery capacity level (%)
• Countdown timer
Bypass Mode
The bypass provides an alternate path for power to the connected equipment and operates in the
following manner:
• Automatic: In the event of an internal fault or should the inverter overload capacity be exceeded,
the UPS performs an automatic transfer of the connected equipment from the inverter to the
bypass source.
• Manual: Should the UPS need to be taken out of service for limited maintenance or repair,
manual activation of the bypass will cause an immediate transfer of the equipment from the
inverter to the bypass source.

2.5.2Transformer-Based UPS Cable Connection
NOTE
After the output transformer is installed, if the startup is on bypass, the UPS has a six-cycle
inrush current that is up to 20 times the rated output current. This must be taken into account
when selecting the input overload protection device at the AC input supply distribution point.
To avoid random tripping on startup, Emerson
protected with a circuit breaker capable of withstanding this initial inrush (the MCB is
derated according to the D curve or TYPE 4).
This UPS is fitted with EMI filters. Earth leakage current is less than 40mA. Transient and
steady state earth leakage currents may occur when starting the UPS. This should be taken
into account when selecting transient RCCB or RCCD (leakage current devices of the UPS and
load).
The MCB of the AC power supply connected to the UPS input must bear this warning:
Disconnect the connection with UPS before maintaining this circuit
The warning is required because the UPS has no autofeeding protection device.
The UPS grounding should be in accordance with local regulations.
A junction box is factory-installed on all models of the Liebert APS to ease cable connection.
Select the appropriate input cables according to Table 5 and Table 6 based upon the UPS rating and
mains frequency. Emerson recommends sizing the frame’s overcurrent protection and wiring to
permit easier UPS system upgrades.

Risk of electrical shock. Can cause property damage, injury and death.
Operating the REPO circuit will NOT trip the manual bypass breaker. If the REPO must shut
off UPS output under all circumstances, the user must tie the REPO into the breaker feeding
the UPS source. Otherwise, voltage may be present on the output connections if the unit is in
manual bypass.
NOTICE
Risk of improper installation. Can cause unintended UPS shutdown and loss of power to the
load.
Run signal cables separately from power cables. Running cables in the same conduit can
cause signal noise, possibly causing the system to shut down.
NOTE
A jumper is factory-installed between Pins 9 and 10 to disable the Main Control Switch. This
will prevent the UPS from being started accidentally during shipment and installation. This
jumper must be removed before the unit can be started.
If the installation does not require connection to a REPO system, the factory-installed jumper

Disabled/ Enabled. If ‘Enabled,’ the system operational parameters will
assume there is a redundant power module in the frame; if ‘Disabled’, the
system operational parameters will assume that all power modules in the
frame are not redundant.
Note: This item is closely related to the ‘Redundant alarm’ setting
Disabled/ Enabled. If ‘Enabled,’ this allows the UPS output power to be
shutdown through remote communication, including the dry contacts and
Liebert IntelliSlot communication cards.
Note: This item is closely related to ‘Remote shutdown delay’
Sets the range of inverter synchronization for bypass frequency operation
and availability
Sets the upper limit of bypass voltage operation and availability
Sets the lower limit of bypass voltage operation and availability
Disabled/ Enabled. If ‘Enabled,’ once a low battery alarm is generated
during a battery discharge, the UPS will continue battery mode operation
until it reaches the end of discharge (EOD) setpoint, then will shutdown
output power, whether the AC mains recovers or not.
Allows an alarm to be generated when the bypass is abnormal
Because the slot 2 and the serial port on the rear panel cannot work at the
same time, you must select one of them to work. If ‘INTERFACE2’ is
selected, the slot 2 can communicate; if ‘RS232’ is selected, the serial
port can communicate.
Sets the battery capacity limit of auto restart feature. When AC mains
power returns, the UPS will charge the battery to the specified battery
capacity before enabling output power.
Sets the delay time of auto restart feature. When AC mains power returns,
the UPS will start a countdown timer based upon the setting before
enabling output power.
Users can change the control password to prevent unauthorized user
from changing any user configurable settings. The default password is
1234567. Once the password is changed, the default password is no
longer operational and users are then required to enter the new password
to enter/change any ‘Settings’ or ‘Battery settings’. If the new password is
forgotten, contact your local customer service center for steps to reset the
password back to the factory default.
Sets a maximum load alarm. This item is closely related to ‘Max load
threshold.’
Sets the threshold of maximum load alarm. When the UPS loads exceed
the threshold, and the maximum load alarm is enabled, an alarm will be
generated.This item is closely related to ‘Max load alarm,’ for example, set
this item to 5.0kVA, when the UPS loads exceed 5.0kVA, an alarm will be
generated.

Follow the instructions below when replacing or adding a system control, system monitor, power,
battery, or charger module. Contact your local Liebert representative if you need to purchase
additional modules to expand your system or contact authorized Liebert service representative for
replacement modules.
5.3.1Removing Modules
1. Remove bezel cover to locate the faulty module. The yellow fault LED will be illuminated on the
faulty module.
NOTE
When removing bezels from a transformer-based UPS, note which have filters and replace
them accordingly. Bezels from the modules will have air filters. There will be no filters on the
bottom three transformer bezels. The transformer has a separate air filter.
For module removal, after unlocking the lever, wait a few seconds to remove the module.
If your system does not contain a redundant module, you may need to manually place the UPS
into manual bypass before removing modules to avoid accidental loss of output power for the
connected equipment.
2. The method for removing a module varies depending on the module type. The two methods are as
follows:
• When removing a power, battery or charger module, use a Phillips screwdriver to remove
the fastener (if installed). Then pull out the lock lever slightly and lift up to unlock the
module.
• When removing a system control or system monitor module, use a Phillips screwdriver
to remove the two screws from the securing holes on each end. Then pull out the lock lever
slightly and slide it to the left to unlock the module.
Troubleshooting
Figure 71 Lever and fastener
3. To pull out a power, charger or battery module:
a. When removing a power module, charger module or battery module: slide it 2/3 of the way out.
It will be stopped by the safety catch.
b. Lift the module up slightly while continuing to pull it out as shown in Figure 72.
c.Support the module and slide it completely out of the unit.
d. When removing a system control or a system monitor module, there is no safety catch because
the modules are lightweight.

Proper maintenance of the UPS is imperative to optimal performance and life of the unit. Emerson
recommends that a certified technician perform preventive and corrective maintenance. Emerson
Network Power Liebert Services is dedicated to ensuring the highest level of performance and
unmatched support for your UPS. Contact your local Liebert representative for service.
6.2Scheduled Maintenance
Emerson recommends performing the following maintenance at least monthly:
• Clean unit.
• Clean or replace filters.
• Verify proper airflow.
Emerson recommends performing the following maintenance annually:
• Verify that all power modules are operating properly.
• Verify that all battery modules are operating properly.
• Verify redundancy (if applicable).
6.3Cleaning Fan Filters
The intake fans contain filters that will need to be replaced or cleaned periodically, depending on the
surrounding environment. Check filters; replace if they are very dirty or damaged.
To clean filters, either use a vacuum to remove the dirt and dust or rinse out the filters under running
water (with the dirt side down) to remove dirt and dust. Blot the filters dry with a towel and allow
air-drying before reinstalling it.
