tion. Make all of the following connections:

1.

AC power cables from input power source circuit breaker (RIB) to UPS Module Input. Observe
phase rotation.

2.

AC power cables from bypass power source circuit breaker (BIB) to UPS system bypass input
at System Control Cabinet (SCC). Observe phase rotation.

3.

AC power cables from UPS Module Outputs to SCC or to switchgear for critical load bus.
Observe phase rotation.

4.

Each UPS Module Output Neutral to SCC or to switchgear for critical load bus. See Section 7.

DANGER
VERIFY THAT ALL INCOMING HIGH AND LOW VOLTAGE
POWER CIRCUITS ARE DE-ENERGIZED AND LOCKED OUT
BEFORE INSTALLING CABLES OR MAKING ELECTRICAL
CONNECTIONS.

ALL POWER CONNECTIONS MUST BE COMPLETED BY A
LICENSED ELECTRICIAN EXPERIENCED IN WIRING UPS
EQUIPMENT, AND IN ACCORDANCE WITH ALL APPLICABLE
NATIONAL AND LOCAL ELECTRICAL CODES.

IMPROPER WIRING MAY CAUSE DAMAGE TO THE UPS OR
INJURY TO PERSONNEL.

!

CAUTION
All shielded cables, non-shielded cables, non-shielded control
wires, non-shielded battery breaker control wires, and non-
shielded remote control wires must be housed in individual,
separate, steel conduits. Placing multiple cables in the same
conduit with other control or power wiring may cause system
failure.

!

CAUTION
See Section 7 of this Manual for an explanation of proper
grounding techniques.

NOTE
Make sure all required wiring between each UPS module and the optional
cabinet(s) is completed. Observe phase rotation.
