Attach the PDU to the Power Module and Battery
Module.
Align and connect the PDU's power module input terminals with the terminals
on the back of the Power Module. Secure the PDU to the Power Module with
four screws A. Before proceeding further, ensure that the Bypass Switch is set
to NORMAL. Remove the utility input terminal block cover B.
Hardwire the PDU to a Utility Power Source.
Pass a user-supplied cable through the knockout on the left side of the PDU
C and connect it to the PDU's input terminals D. Replace the terminal block
cover. Connect the other end of the cable to a utility power source.
Connect the battery module to the power module.
Consult the owner’s manual that came with your battery module. Fully insert
the connector on the end of the battery module’s cable Einto the connector
on the rear panel of the power module F. Small sparks may occur; this is
normal. NOTE: the power module does not contain internal batteries and will
not start until a battery module is connected. The battery modules are fully
charged prior to shipping. However, before expecting full backup capability
(particularly if the battery module has been stored for an extended period) after
the UPS system is connected to a utility power source, allow the battery module
to recharge for 12 hours. Once the UPS system is in use, it will charge the bat-
teries and maintain the charge level automatically. If needed, connect addi-
tional battery modules in a daisy-chain with each module’s cable inserted into
the previous module’s connector G.

Connection
• Wiring must be done by a qualified electrician.
• When making wiring connections, observe the cable connection regulations appropriate to your area [e.g. National Electrical Code
(NEC) in the U.S.] at all times. Be sure to install an easily accessible disconnect switch in your installation wiring so you may cut off
the UPS’s AC input during fires and other emergencies. Ensure that cables are fitted with cable sleeves and are secured by connector
clamps. Tighten connections with a torque of not less than 24-28
inch-pounds (2.7-3.2 NM).
• Make sure that your equipment is properly grounded.
• Using cables of improper size may damage your equipment and
cause fire hazards. Choose appropriate cabling and protection
circuits to make wiring connections. Ground conductors must be
the same size and type as the power conductors used.
• Refer to National Electrical Code (NEC) guidelines for proper
wire gauge and output protection circuit requirements.

Contacts on Power/Battery Module
WARNING! High Voltage!
Risk of electrical shock!
Due to the presence of high voltage internal
batteries, even without AC present, these
contacts are live!
Do not let these contacts touch any surface!

Power ON
Turn UPS inverter ON: Press the UPS's “ON” Button I until you hear a
beep to begin inverter operation. Your UPS will perform a brief self-test and
show the results on the LCD Display H. See “Startup Self-Test” in the
“Operation” section for the display sequence.
