Battery Compartment Precautions
Batteries are factory installed in the DC UPS module. Final battery connections will be made by
Emerson after the DC UPS module is installed. DO NOT MAKE BATTERY CONNECTIONS. The
following precautions apply to the battery compartment that is part of the DC UPS module.
WARNING
Special safety precautions are required for procedures involving handling, installing, and
servicing batteries. Observe all battery safety precautions presented here and in the battery
instruction manual. These precautions should be followed implicitly at all times.
WARNING
A battery can present a risk of electrical shock and high short circuit current. Servicing of
batteries should be performed or supervised only by properly trained and qualified personnel
knowledgeable about batteries and the required precautions.
The following precautions should be observed when working on batteries:
• Remove watches, rings and other metal objects.
• Eye protection should be worn to prevent injury from accidental electrical arcs.
• Use certified and well maintained insulated tools.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if battery is inadvertently grounded. If the battery is inadvertently grounded,
remove source from ground. Contact with any parts 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 (applicable to equipment and remote battery supplies
not having a grounded supply circuit).
• Risk of explosion if battery is replaced with an incorrect type or if polarity is reversed.
When replacing batteries, replace with the same manufacturer and type, or equivalent. See
your local Emerson representative for a list of approved batteries.
• Dispose of used batteries according to the instructions provided with the batteries. Do not
dispose of batteries in a fire. They may explode.
In addition to the hazard of electric shock, gas produced by batteries can be explosive and
sulfuric acid can cause severe burns. Do not open or mutilate batteries. Released electrolyte is
harmful to the skin and eyes, and is toxic. If electrolyte comes into contact with skin, the
affected area should be washed immediately with large amounts of water.

2.2 Row-Based Installation Example
The NetSure ITM DC UPS system provides the flexibility to meet the needs of any data center.
The NetSure ITM DC UPS system is delivered fully configured for quick and easy field installation.
Multiple DC UPS modules can easily be connected on site in order to increase capacity. Each module
takes only 24" (w) x 41" (d) of floor space, including batteries and primary distribution. The NetSure
ITM DC UPS system is typically installed in the middle or at the end of a row of server racks. This
makes the system uniquely flexible and scalable. Deploy only the capacity that is initially needed;
modules can be added at any time to existing units on the data center floor.
Figure 4 depicts a top distribution feed installation powering IT racks. Depending on your site and
budget requirements, the NetSure ITM DC UPS solution can either be installed as a single
deployment, or incrementally by row. In either scenario, DC distribution cabling to each rack is
reduced by placing the NetSure ITM DC UPS in-the-row.
Whatever the physical layout of your data center, the NetSure ITM DC UPS allows for maximum
space for IT equipment. With DC UPS building block modules, you can mix and match configurations
and standard layouts to fit your available space.

3.0 P
OSITIONING THE
This section describes the environmental and mechanical considerations that must be taken into
account when planning the positioning and cabling of the DC UPS system. This section also provides
procedures for physical installation of the DC UPS cabinet.
Because every site is unique, some subsections present a guide to general procedures and practices
that should be observed by the installing engineer, rather than step-by-step installation instructions.
DC UPS S
YSTEM
3.1 General Requirements
• The installer should be familiar with the installation requirements and techniques to be used in
securing the DC UPS module (cabinet) to the floor. It is up to the customer to determine the
requirements for anchoring the cabinet to the specific type of floor at the site, select proper
anchors, and to investigate the proper use of the anchor.
• This product is intended only for installation in a Restricted Access Location on or above a noncombustible surface.
• Front and rear access is required for installation and operation (see Clearances in this section).
3.2 General Guidelines for Positioning the DC UPS Modules
Choose a location for the DC UPS system that offers:
• Easy connection to inputs, outputs, and alarms.
• Air circulation sufficient to expel heat produced by the DC UPS system.
• Protection against moisture and excessive humidity.
• Protection against dust and other particulate matter.
• Enough space to service the DC UPS system (see Clearances in this section).
• Compliance with fire prevention regulations and practices.
3.2.1 Cable Entry
DC distribution and alarm cables enter the DC UPS module from the top or bottom, depending on
module configuration (top distribution feed or bottom distribution feed).
AC input cables can enter either at the top or bottom. Conduit openings are provided in both
locations.
3.2.2 Environmental Considerations
Before installing the DC UPS system, verify that the room satisfies the environmental conditions
stipulated in 7.2 - Environmental, paying particular attention to the ambient temperature and air
exchange system. Also refer to 7.2 - Environmental for details on heat dissipation.
The DC UPS system should be installed in a cool, dry, clean-air environment with adequate
ventilation to keep the ambient temperature within the specified operating range +23°F to +95°F
(-5°C to +35°C).
• Batteries are installed in the DC UPS module’s battery compartment. Temperature is a major
factor in determining battery life and capacity. Battery manufacturers recommend an operating
temperature of 77°F (25°C). Ambient temperatures higher than this reduce battery life;
temperatures lower than this reduce battery capacity. For optimal battery performance and
service life, inlet air temperature to the battery compartment (from the front of the system)
should be maintained between +68°F to +77°F (+20°C to +25°C).
The DC UPS module is cooled by internal fans. Cooling air enters the system through the front of the
unit and is exhausted out the top. To permit proper air flow and prevent overheating, do NOT block or
cover the ventilation openings or blow air down onto the unit. Ventilation clearance above the unit
must be a minimum of 8 in. (203mm).

Installation Manual, Section 6040 (Issue AB, April 8, 2013)
3.2.3 Mechanical Considerations
The DC UPS system can be comprised of up to four (4) modules (cabinets), depending upon your
power requirements. All modules used are the same size and are designed to be positioned side-byside to form an aesthetically appealing equipment suite. The system always contains one (1) Primary
Module. For increased power demands, up to three (3) Expansion Modules may be added. Locate the
Primary Module at the far left or far right of the row. Remove the side panel from the Primary Module
from the side that will face adjacent Expansion Modules. Place the first Expansion Module next to the
Primary Module. Place additional Expansion Modules (if required) next to each other. Install the side
panel removed from the Primary Module to the open side of the last Expansion Module in the row.
NOTE
When the DC UPS system consists of multiple modules, the switches inside the modules are
pre-set at the factory to identify the module as the Primary Module, 1st Expansion Module, 2nd
Expansion Module, or 3rd Expansion Module. When placing modules, refer to the nameplate
identification number (see Table 1) to ensure the Primary Module is placed on the end, and
Expansion Modules are place in sequential order.
Clearances
There are no ventilation grilles on the sides of the DC UPS module. The DC UPS modules may be
placed with the sides touching or against a wall.
To enable routine tightening of power terminations within the DC UPS module, make sure there is
sufficient clearance in front and rear of the DC UPS module to permit free passage of personnel and
that the front door can be fully opened.
Leave a minimum of 8 in. (203mm) between the top of the DC UPS module 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.
Leave a minimum of 36 in. (914 mm) between the back of the DC UPS module and a wall to permit
adequate air circulation for the battery compartment fans and facilitate maintenance access.
3.3 Floor Installation
Refer also to 3.1 - General Requirements.
The diagrams in 2.0 - Installation Drawings and Recommended Tools and Test Equipment
show the location of holes in the base plate for bolting the DC UPS module to the floor.
If the module is to be placed on a raised floor, it should be mounted on a floor stand that will support
the equipment point loading. Refer to the cabinet-bottom views in 2.0 - Installation Drawings and
Recommended Tools and Test Equipment to design this pedestal. Contact your Emerson Sales
Representative for a floor stand designed for this system (see Figure 5).

3.4 Considerations in Moving the DC UPS Module
3.4.1 Transporting
Ensure that the DC UPS module weight is within the designated surface weight loading (lb./ft2 or kg/
cm2) of any handling equipment. The DC UPS module weighs 3240 lb. (1470 kg), fully loaded.
WARNING
Ensure that any equipment that will be used to move the DC UPS module has sufficient
lifting capacity. Ensure adequate personnel and lifting equipment are available when taking
the module off its shipping pallet. The module presents a tipping hazard. Do not tilt the
module further than 10 degrees from vertical.
The DC UPS module is fitted with casters. Take care to prevent movement when unbolting
the module from its shipping pallet. 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.
WARNING
Batteries are factory installed in the DC UPS module’s battery compartment. Care must be
taken when maneuvering modules with batteries. Keep such moves to a minimum. See
Battery Compartment Precautions on page 2.
3.4.2 Moving a DC UPS Module
Cabinet Preparation
1. Inspect the cabinet as described in 1.1 - External Inspections and 1.2 - Internal Inspections.
2. Remove the front and rear bottom panels to gain access to the bolts securing the cabinet to the
pallet.
Moving DC UPS Module from Shipping Pallet
Use lifting equipment, such as a forklift or similar equipment, appropriately rated for the weight of
the load to move the DC UPS cabinet from its shipping pallet.
When moving a DC UPS cabinet with a forklift or similar equipment, make sure that the fork is of
sufficient length for the pallet size and capable of lifting the cabinet. Also use a forklift with
adjustable forks or a narrow type.
1. Close the front door.
2. Slide the forklift into place.
3. Unbolt the cabinet from the pallet.
4. Lift the cabinet. The pallet should drop off from its own weight.
5. Carefully move the DC UPS module to its installation location or set the DC UPS module down on
its casters if it is to be rolled into position.
Moving DC UPS Module to Installation Location
The DC UPS module may be rolled on its casters when moving the unit a short distance. For longer
distances, move the DC UPS module with a forklift or similar equipment to ease the relocation and to
reduce vibration.
3.4.3 Final Positioning
Note that the DC UPS modules sit on four casters. When the DC UPS module has been finally
positioned, ensure that the adjustable stops are set so that the DC UPS module will remain
stationary and stable.

LECTRICAL CONNECTIONS
The DC UPS system requires grounding, DC output distribution, AC input power, alarm/control, and
battery wiring once it has been mechanically installed.
If the system consists of multiple DC UPS modules, battery and ground/return busbars must be
interconnected and alarm/control interconnect wiring between modules must be made.
4.1 Wiring Information and Guidelines
4.1.1 Cable Lengths (Floor or Cabinet Top to Connection Point Inside DC UPS Module)
To help calculate the total cable length required, refer to Table 2 for the distance from the floor or
cabinet top to selected connection points inside the DC UPS module. Determine the cable length
required to reach the DC UPS module, then add the appropriate length from the table and adequate
slack for repair and maintenance.

4.1.2 Recommended Wire Sizes, Recommended Lugs, and Torque Requirements
The main factors affecting the choice and size of wires are voltage, current (also taking into account
overcurrent), room temperature, and installation conditions.
The power cables of the system must be sized with respect to the following:
• AC Input Cables - The AC input cables must be sized for the module’s maximum input current.
• DC Output Distribution Cables - The DC output distribution cables must be sized for the
module’s output breakers or fuses.
• Battery Cables - The DC UPS module contains a battery compartment. Battery cables are
factory supplied and sized accordingly.
Refer to Termination Type, Recommended Wire Size, Recommended Lugs on page 59 for
recommended wire sizes and recommended lugs. Refer to the illustrations in this section for torque
requirements.
NOTE
The above referenced section gives nominal currents for determining the size of DC UPS
module power cables. Other important factors to consider include cable route length and
coordination with protective devices.
4.1.3 Wiring Guidelines
The following are guidelines only and are superseded by the NEC and applicable local codes where
applicable.
• The grounding cable connecting the DC UPS module to the main ground system must follow the
most direct route possible.
• Consider using paralleled smaller cables for heavy currents—this can ease installation.

4.4.7 Optional Emergency Power Off (EPO) Connection (to Primary Module only)
The DC UPS module has an Emergency Power Off (EPO) function operated by a remote contact
provided by the User.
WARNING
The EPO circuit operates with -48Vdc. There is -48Vdc present on the terminals the EPO
jumper connects to. There is -48Vdc present on these same terminals that an external EPO
switch will be connected to.
NOTE
The external EPO switch wiring must be double-insulated. The wire must be 600V, 18-16 AWG
stranded for maximum runs between 82 and 197 feet (25-60m), respectively.
If the EPO function is desired, locate the EPO jumper in the Primary Module (see Figure 19).
Remove the EPO jumper (the jumper connects from the bottom terminal of the EPO terminal block
and the bottom of EPO Fuse F11). Connect a customer provided external normally closed switch
between the bottom terminal of the EPO terminal block and the bottom of the EPO Fuse.
The following occurs when the EPO switch is opened.
• The battery LVD contactor in each DC UPS module opens, disconnecting the battery from each
module.
• If the ACU+ "EPO Enabled" option is set to YES, the PCUs in each DC UPS module shut down
after 5 seconds. If the ACU+ "EPO Enabled" option is set to NO, PCUs remain running.
NOTE
The Emergency Stop action within the DC UPS module opens the battery LVD contactor and
(if programmed in the ACU+) shuts down the PCUs.
It does not internally disconnect the input power supply. To disconnect ALL power to the DC
UPS module, open the upstream feeder breaker(s) when the remote EPO is activated.
It does not disconnect the SM-BRC. The SM-BRC will still be powered by the batteries.

1. Make similar connections between each adjacent Expansion Module.
SM-BRC RS-485 Termination Resistor Setting in Last DC UPS Module
1. A jumper on the SM-BRC circuit board is used for selecting a termination resistor for the RS-485
connection. RS-485 termination is disabled when the jumper is across pins 1 and 2 (default). It is
enabled when the jumper is across pins 2 and 3. See Figure 22 for the location of the jumper.
In most cases, RS-485 termination is not necessary because maximum baud rate is 19200 bps
(default is 9600). RS-485 termination is recommended when intermittent communications occur.
If there are intermittent communications errors, it is recommended to set the termination resistor
on the SM-BRC in the last module to the enabled position (jumper between pins 2 and 3) instead
of the factory disabled position (jumper between pins 1 and 2).

Installation Manual, Section 6040 (Issue AB, April 8, 2013)
6.3.1 Initially Starting the DC UPS System and Verifying System Operation
The NetSure ITM DC UPS must be fully installed and commissioned before startup.
Procedure
1. Open the front door on each DC UPS module.
2. Apply AC input power to each DC UPS module by closing the external AC disconnect(s) or
protective device(s) that supplies power to each DC UPS module. If the dual AC input feed option
is furnished, there will be two (2) devices per DC UPS module.
3. On each DC UPS module, close the main AC input circuit breaker. If the dual AC input feed
option is furnished, a safety latch is provided on the circuit breakers to prevent both circuit
breakers from being placed in the ON position. Slide the latch over to allow the desired circuit
breaker to be turned ON.
4. On each DC UPS module, close all PCU AC input circuit breakers. Note that each circuit breaker
feeds two (2) PCUs.
5. In the Primary DC UPS module, once the ACU+ Controller is powered on, a starting... screen
appears followed by a language screen.
Press “” or “” to select the desired language. Press ENT to confirm the selection. If no key is
pressed within 30 seconds, the ACU+ Controller automatically selects the displayed language.
Refer to the NetSure ITM Operation Manual (Section 6047) for ACU+ Controller local menu
operating instructions.
Once initialized, the ACU+ Main Screen displays.
6. With an external meter, measure battery voltage.
7. Adjust the system’s float voltage to within approximately 0.5V of battery voltage.
8. In each DC UPS module, install the three battery disconnect fuses.
9. Adjust the system’s float voltage to 54.5Vdc.
10. In each DC UPS module, place each distribution circuit breaker to the ON position or install all
distribution fuses.
11. In the Primary DC UPS module, verify that there are no alarms present on the ACU+ local
display.
6.3.2 Setting Common Controller Parameters
Navigate through the controller menus and submenus to set common controller parameters (time,
date, IP address, etc.). Refer to Section 3.5 of the NetSure ITM Operation Manual (Section 6047) for
common tasks performed locally.

6.3.3 Changing the Numbering Scheme of the PCUs
Follow these procedures to change how the ACU+ identifies (numbers) the PCUs installed in the
system. These procedures are performed from the ACU+ Controller’s local display and keypad.
Initial Installation (numbering the PCUs per their Physical Location in the System)
1. Go to Main Menu / Settings / PCU.
2. Press Enter.
3. Navigate down to PCU 1 (001).
4. Press Enter.
5. Look for the PCU installed in the system with a flashing LED.
6. Press Enter.
7. Press the Up or Down Arrow until the number displayed is the same as the physical position of
the PCU with the flashing LED.
8. Press Enter.
9. Press ESC.
10. Navigate down to the next PCU and repeat steps 4 thru 10.
11. After all PCUs are renumbered, go to Main Menu / Control / PCU / All PCU Ctrl.
12. Press Enter.
13. Navigate down to Confirm Posi/PH.
14. Select Yes, then press Enter.
15. Verify that the ACU+ now numbers the PCUs via their physical position in the system by going to
Main Menu / Status / PCU and scrolling down to each PCU listed in the display. Compare the
PCU number highlighted in the display with the physical position of the PCU with the flashing
LED.
Swapping PCUs Physical Positions without Adding or Removing the Number of PCUs
1. If you swap PCUs, the ACU+ numbering stays with the PCUs. For example, if PCU in physical
position 1 is swapped with PCU in physical position 2, the ACU+ numbers the PCU now installed
in physical position 1 as 2 and the PCU now installed in physical position 2 as 1. To correct this,
repeat the steps shown in the "Initial Installation" procedure for ONLY the two PCUs that were
swapped.
Removing a PCU without Replacing It
1. Remove the PCU.
2. Go to Main Menu / Control / PCU / All PCU Ctrl.
3. Press Enter.
4. Navigate down to Confirm Posi/PH.
5. Select Yes, then press Enter.
6. Now, when you view the voltage and current for the removed PCU, the fields will be highlighted
in BLACK to indicate this PCU is not present. Also, the WEB interface shows that PCU
information GREYED out.
7. If you now re-install that same PCU in it's previous physical position, it will retain its previous
slot number.
Replacing a Previously Installed PCU with a New PCU
1. Remove a previously installed PCU.
2. Clear the PCU Lost Alarm.
3. Install the new PCU.
4. The new PCU is automatically assigned the same numbering as the original PCU it replaced.

7.5.11 Standard Features
Type of Power Conversion Circuit: High frequency.
Float Charging Output Mode: In this mode of operation, system output voltage is constant and
output current does not exceed the current limit setting. During normal operation, the battery is not
required to furnish load current and remains in a fully charged condition.
Float voltage is set via the Controller, default @ 54.5V for furnished batteries.
NOTE
If the current demanded by the load exceeds the current limit setting of the system, the battery is
required to furnish the difference in load current and begins discharging.
Input Protection:
a. Input Over/Under Voltage Protection: The PCU shuts down and its protection indicator
(yellow) illuminates when the input voltage is lower than 260VAC or higher than 530VAC.
This condition is reported to the power system Controller and the power system Controller
processes the alarms accordingly.
b. Input Fusing: Input fuse is provided in each PCU. This fuse is not customer replaceable.
Output Protection:
a. Current Limiting: The maximum current delivered by the system is programmed via the
Controller. The Controller automatically adjusts the current limit circuit on each PCU so that
this value is not exceeded. If a PCU fails, the Controller automatically resets each remaining
PCU's current limit point to maintain this value. The Controller also insures that the current
limit circuit on any PCU is not set above 110% of its capacity. The default current limit
setting is the sum of each installed PCU's output rating. If an additional PCU is added to the
system, the system current limit is automatically increased by the rating of the new PCU and
the new current limit value is displayed.
The current limiting point is set via the Controller.
b. Output Fusing: Output fuse is provided in each PCU. If a fuse opens, local and remote PCU
Fail Alarms activate. This fuse is not customer replaceable.
c. High Voltage Shutdown:
1. Internal: If PCU output voltage exceeds an adjustable preset value, the PCU shuts down.
•After approximately 5 seconds, the PCU automatically restarts. If PCU output voltage
again exceeds the high voltage shutdown value within 5 minutes, the PCU shuts down
and locks out. Manual restart is then required. If the PCU does not experience a high
voltage condition within the 5 minute time period, the restart circuit is reset.
•Only the PCU causing the high voltage condition shuts down.
•The high voltage shutdown point is set via the Controller.
2. Backup: If PCU output voltage exceeds a second (non-adjustable) value, the PCU shuts
down and locks out regardless of load. Manual restart is then required. The fixed
hardware HVSD is 59.5V (within the range of 58.5 to 60V).
High Temperature Protection:
a. When the PFC board temperature is higher than 85°C, the PCU turns off. When the PFC
board temperature is lower than 75°C, the PCU resumes normal operation, and the hysteresis
is at least 10°C.
b. When the difference between “ambient temperature" and "PFC board temperature” is greater
than 5°C, the PCU turns off. When the difference between “ambient temperature" and "PFC
board temperature” is less than 2°C, the PCU resumes normal operation, and the hysteresis is
at least 3°C.
c. When the DC board temperature is higher than 105°C, the PCU turns off. When the DC board
temperature is lower than 95°C, the PCU resumes to normal operation, and the hysteresis is
at least 10°C.

Fan Fault Protection: An alarm will be generated upon a fan fault. In such cases, the fault
indicator (red) on the PCU front panel will flash and the PCU will also inhibit its output. Autorecovery is enabled upon the clearing of the corresponding fault.
PFC Over/Under Voltage: The PCU will shut down when its bus voltage is higher than the over
voltage set point or is lower than the under voltage set point. During such conditions, the PCU does
not output any power and its protection indicator (yellow) will light up.
Active Load Sharing (PCU): The PCU uses advanced digital active load sharing technology that
maintains balancing to within ±3A. The difference in the average current between PCUs is <±3A for
loads in the 10 to 100% range. The Controller also has a PCU Load Sharing function.
Startup Time: The PCU has two startup modes:
a. Normal Soft Start Time: The duration from the time when the PCU is powered on to the
time when the PCU provides output voltage is <8s.
b. Current Walk-In: The rise time of the PCU output voltage is >8s at 90% of the rated load,
and the maximum time is 90s at 100% of the rated load.
Hot Swappable: The PCU is designed to be plug-and-play. The PCU can be inserted or removed
from a live DC power system with no damage. When the PCU is plugged into the system, the system
output voltage will not be affected.
Cooling: Each PCU contains a fan for forced convection cooling.
Fan Control: When the PFC bus voltage is within a normal range, the built-in processor adjusts the
fan’s speed according to the PCU’s internal temperature and output current. For example, a higher
temperature or output current will increase the fan speed. Above 45°C at full load, the fan operates at
full speed. When the PFC bus voltage is abnormal, such as very low bus voltage, the fan turns off.
Communication Failure: The PCU’s protection indicator (yellow) will flash should it experience a
communication failure. The failure information will be reported to the Controller and the Controller
will process the failure accordingly. During a communication failure, in order to protect the battery,
the PCU output voltage will automatically adjust to 53.5 V (this is a default value which can be
modified using the Controller). The PCU will revert to normal operation once normal communication
is restored.
Unbalance of PCU Output Current: When the output current of the PCUs in a DC power system
is unbalanced, the PCU having the unbalanced output current will be identified automatically and its
protection indicator (yellow) will turn on.
The failure information will be reported to the Controller and the Controller will process the failure
accordingly.
Local Status and Alarm Indicators:
a. Power (Green)
b. Protection (Yellow)
c. Alarm (Red)
d. A 10-segment Green LED is located on the front panel to represent output current, each
segment represents 10A.
