Wiring Considerations 19
8.0 WIRING CONSIDERATIONS
Refer to AppendixA - Site PlanningData and i nstallation drawings (Figure 8 through
Figure 58). Determine AC currents for your system (kVA, voltage, and options). Also refer to
equipment nameplate for the model number,r ating,and voltage. Refer to Table 1 and Table 2
for wire termination data.
WARNING
ALL POWER CONNECTIONSMUST BE COMPLETED BY A
LICENSED ELECTRIC IAN THAT IS EXPERIENCED IN WIRING
THIS TYPE OF EQUIPMENT. WIRING MUST BE INSTALLED IN
ACCORDANCE WITH ALL APPLICA BLE NATIONAL AND LOCAL
ELECTRICALCODES. IMPROPER WIRING MAY CAUSE
DAMAGE TO THE EQUIPM ENT OR INJURY TO PERSONNEL.
VERIFY THAT ALL INCOMING HIGH AND LOW VOLTAGE
POWER CIRCUITS ARE DE-ENERGIZEDAND LOCKED OUT
BEFORE INSTALLING CABLE S OR MAKING ANY ELECTRICAL
CONNECTIONS.
NOTE
Use 75°C copper wire. Select wires izebased on the ampacities in Table 3
of this manual, a reprint of Table 310-16 and associated notes of the
National Electr ical Code (NFPA 70).
CAUTION
The weight of power cables must be adequately supported to
avoid stress on bus bars and lugs.In addition to weight support,
the followingrestraining method is recommendedto control cable
movementduring external fault conditions:Wrap line cables
together at 6 inches and 12 inches fr om the terminals with 5
wraps of 3/8inch nylon rope or equivalent(tensile strength of
2000 pounds). Support remainderof cable with 5 wraps every 6
inches or 1 wrapevery 1 inch.
