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.
