General Alerts
WARNING
Risk of serious personal injury or damage to equipment and
property. Always observe the following:
•Install and operate unit in a restricted access location. A
restricted access location is an area to which access can be
gained only by service personnel using a special tool, lock
and key, or other means of security and which is controlled
by the authority responsible for the location.
•Install the unit in locations where children are likely not to be
present.
•Install earth connection to the unit before connecting AC
input due to high leakage current.
•Installation, operation, and service must be done by
qualified technicians, with all wiring and connections done in
accordance with the local electrical codes.
•Input voltages can range up to 240 VAC. All upstream AC,
load and battery breakers must be shut OFF prior to
installation. The system must be completely de-powered.
•All AC connections must conform to local codes and
regulations.
•Use caution when handling unit under load as surface can
reach hot temperature.
•Do not work alone under hazardous conditions.
Always observe the following for applications requiring a
backup battery:
•Use only a battery with rating and capacity appropriate for
the model of power supply in use.
•Use an appropriate DC overcurrent protection device in-line
with the backup battery connection.
•Use wire and connectors rated for the maximum load
current.
•Ensure battery polarity is correct before connecting.
•Do not attempt to charge a frozen battery.
•Handle batteries with care, never short circuit battery
terminals.
•Always install batteries in well-ventilated areas.
•Always consult with battery manufacturer and observe all
battery manufacturer recommendations.

iv
CAUTION
Risk of personal injury or damage to equipment and
property. Always observe the following:
•Install in a protected environment, keep sources of moisture
away from unit.
•Ensure the total power consumption of the load does not
exceed the continuous rated capacity of the power supply
output.
•Install appropriately rated surge suppression systems.
•Provide adequate support for the rear of the unit without
obstructing the air inlet or outlet openings.
•Remove all metallic jewelry before working with the unit.
•Wear appropriate eye protection and always use
appropriate tools during installation.
NOTICE
•The unit must be properly handled, mounted, and installed.
•Do not block air inlet or outlet openings.
NOTE: Due to the detection circuitry internal to the unit, it may be possible
to measure a voltage on the terminal(s) even if that terminal’s
breaker is open (with no load connected). This is normal operation.
The detection circuitry is a high-impedance circuit, and while a
voltage may be present on the output terminal, it is purely a signal
voltage and does not support loading. Any load device connected
to the output will immediately pull this voltage to zero volts.
Product Alerts
WARNING
Risk of serious personal injury or damage to equipment and
property. Always observe the following:
•Operate the supply from a grounded 3 wire 120 VAC or
230/240 VAC source (50 or 60 Hz) with a branch circuit
breaker rated 30 amps or less.
•If a lithium-ion battery is used, it must have an integrated
battery management system (BMS) to protect the battery
cells from inappropriate voltage or current levels.

2.5 Rack Mounting
CAUTION
Provide adequate support for the rear of the unit without
obstructing the air vents.
Mount the unit in an enclosed standard 19-inch equipment rack or other
restricted access location, using rack mounting screws (not supplied).
Support the rear of the unit with rack shelf supports or back rail if required.
2.6 Ground Connection
Connect an 8 AWG ground bonding wire from the chassis ground stud to
the rack.

WARNING
Risk of serious personal injury or damage to equipment and
property. Always observe the following:
•When using a backup battery, ensure the nominal battery
voltage is correct for the model of power modules installed,
and the battery positive is connected to the positive (+)
terminal and the battery negative is connected to the (−)
terminal. Note that the BAT terminal on the BMM may be
internally tied to either the (+) or (−) shelf output through the
LVD contactor, depending on the polarity of the unit used.
•Use an appropriate DC overcurrent protection device such
as a fuse or circuit breaker in line with and near to the
battery connection.

WARNING
•Do not tie either of the unit’s main output to the BAT
terminal on the BMM, as this may short circuit the battery or
bypass the internal LVD circuitry in the BMM.
•Do not ground both the load and battery as this may bypass
the internal LVD circuitry or create a short circuit to the
system.
•AC input wiring to the Modular Power Series unit must be
protected using an outlet with a branch rated circuit breaker
of 30 amps or lower value.
•De-energize the system before making any change to the
wiring and connections.
2.7 Sensor and Alarm Connections
1. The ALARM connector allows the MPS to report faults to an external
monitoring device through a form-C contact. If needed, connect form-C
contact monitoring wiring to the ALARM connector as shown in Table 5.
On a dual-shelf system, the primary shelf contacts are flagged for all
system alarms while the secondary shelf contacts indicate secondary
power module faults only. Use 22–26 AWG wire. Refer to Tables 15–18
for which conditions will trigger a form-C alarm.

2. The AUX connector allows the MPS to monitor up to four external form-
C circuits and a battery temperature probe.
3. Connect the external Battery Temperature Sensor (ICT-TMP, included
with a BMM-equipped shelf, for use with lead-acid batteries only) to the
AUX connector as shown in Table 6. This will allow the MPS to
compensate for the output voltage according to the battery temperature.
Use 22–26 AWG wire.

Mount the sensor to the mid-level side of the middle battery in a battery
bank using the adhesive-backed clip, as shown below. The rate of
voltage compensation (with optional BMM installed) can be adjusted
through the ICM front display panel interface, or the GUI in the Battery
Backup Settings section. The default compensation is 0 mV/C per cell
(no compensation). Adjust this according to the battery manufacturer’s
recommendation to enable charge voltage temperature compensation.
Figure 3. Battery Temperature Sensor Installation
NOTE: Battery temperature is assumed to be 25 °C if no sensor is installed.
4. Install wiring to monitor up to four external voltage-free form-C alarm
contacts, typically for external sensors such as a door or window switch,
smoke detector output, or water detector, etc.
5. Enable the alarm inputs and set the contact logic (normally open or
normally closed) in the GUI, Alarms Settings & Control tab (see Section
4.6.2).
2.8 Load Connections
Make connections to the load using wire and connectors appropriately rated
for the maximum output current capability of the unit. The load may be
powered in three different ways.

not connect the loads to the DC Output bus bars until the software has been
configured (see Section 3.2.3 or Section 4.2.2).
Figure 4. The DC Output Bus Bars
If using the LDM outputs, an "Output" (labelled + or − depending on polarity)
and "Return" (labelled RTN) connection are provided for each channel (see
Figure 5 and Figure 6).
Figure 5. The LDM
Figure 6. The LDMP
The LDM provides four remotely controlled and monitored outputs, with front
panel overcurrent protection provided by hydraulic-magnetic circuit
breakers (see Section 2.11 for the installation instructions for the breakers).
The LDM maximum current rating is 80 amps. Each output can accept 30
amps maximum, 25 amps continuous.
