Power Wiring
Requirements
Power wiring requirements are given in the tables below. Wire should
be copper with 75
°
C (167
°
F) minimum rating, per NFPA 79 unless
otherwise noted. Phasing of main input power is arbitrary and earth
ground connection is required for safe and proper operation.
1394 Power Wiring Requirements
1
The input power terminal designated PE is electrically common to the system module single point bond bar, so the
ground connection at PE is optional. However, the ground connection at the single point bond bar is mandatory.
2
105° C (221° F), 600V.
Note: Refer to the section Understanding External Shunt Connections
on page 3-34 for more information regarding the COL, INT, and
DC+ connections.
IMPORTANT
The National Electrical Code and local electrical
codes take precedence over the values and methods
provided.
