This section describes requirements for AC power connections to the local electric utility company and procedures
for connecting an auxiliary generator set.
The electrical connections to the field cabinet should be installed by qualified electricians and conform to the NEC
and all state and local codes.
Connections between the service entrance, AC power panel, and auxiliary generator inlet (if equipped) for each field
cabinet are shown on a decal placed inside the door. This decal provides a wiring diagram of the AC power group(s)
ordered.

ONNECTIONS
For service entrance applications, arrangements should be made with the local power company to furnish a suitable
power drop to the field cabinet site. Field cabinets equipped with the Valere power shelf can use 120 V AC or 120/
240 V AC single-phase service or 208Y/120 V AC service using the two 120 V AC lines. When configured for use
with 120 V AC service, only one pole of the main breaker is used. Use of 9.5 A rectifiers in the Valere power system
requires 208Y/120 V AC service using the two 120 V AC lines.
The maximum input current of the PG-FlexPlus field cabinet is listed in
