Cord Retention Bracket (for models with IEC receptacles)

UPS models that utilize IEC inlets and receptacles have an included accessory that may be installed to 
help secure the input and output cords in place. 

To install the cord retention bracket:

1.   Remove the four screws from the right side of the rear of the UPS

2.   From the top, open cord retainer.

3.   Reinstall screws in the rear of the UPS.

4.   Secure each IEC cord using supplied tie wraps. Thread one end of tie wrap through the hole in the 

cord retainer and around IEC cord. Secure to other end of the tie wrap.

Electrical 
preparations

WARNING: 

 Before connecting any input wiring to the UPS, take precautions to insure that all circuits 

being used are the proper voltage and current required for the UPS. If this UPS is not used with the 
supplied power cord, care must be taken to use properly rated cords (see  “Appendix A: Features and 
Specifications” on page 23) which comply with all regional and local codes.

WARNING: 

UPS output receptacles are energized when the front panel power switch is in the “ON” 

position (green LED is illuminated).

WARNING: 

Electrical shock hazard: Even when the UPS is disconnected from the mains, hazardous 

voltages may still exist at the output receptacles of the UPS. The UPS receives power from more than one 
source – AC input and DC input from batteries. All input sources (AC and DC) must, therefore, be 
disconnected before carrying out maintenance work inside the UPS.

Connections

Battery Connections

WARNING: 

Before connecting a battery pack to the UPS, the circuit breaker of the battery pack must be 

switched to “OFF.” After electrical connection with the UPS is established, the breaker must be switched 
to “ON.”

NOTE: 

Each Battery Pack contains two battery connectors. The first battery pack is connected to the UPS 

using the cable supplied with the pack. Each additional extension battery pack is connected by attaching 
its cable to the previous pack

If additional battery cabinets are to be used, they should be connected prior to connecting the UPS to the 
input power. To connect external battery cabinets, follow the steps below.

1.   Set the circuit breaker on each battery cabinet to the “OFF” position.

2.   Connect battery plug at the end of the cable attached to the battery cabinet closest to UPS to the 

battery receptacle on the rear of the UPS.

3.   Connect the battery plug at end of the cable from the next battery cabinet to the battery receptacle on 

the battery cabinet plugged into UPS.

4.   Continue “daisy-chaining” the batteries until all are connected.
