Section 5. Wiring Diagrams

The reconnection procedure
reconnections only. Adjust the governor and voltage
regulator at time of frequency adjustment.
The following information illustrates the reconnection of
4-lead or 12-lead generator sets. In all cases, follow the
National Electrical Code (NEC) guidelines.
Reconnect the stator leads of the generator set to
change output phase (12-lead models only) or voltage.
Refer to the following procedure and the connection
schematics. Follow all safety precautions at the front of
this manual and in the text while performing this
procedure.
NOTE
Order voltage reconnection decal 246242 from an
authorized service distributor/dealer and affix decal to
generator set after reconnecting to a voltage different
than the nameplate.
WARNING
Accidental starting.
Can cause severe injury or death.
Disconnect battery cables before working on
generator set (disconnect negative lead first and
reconnect it last).
Disabling generator set. Accidental starting can
cause severe injury or death. Turn generator set
master switch to OFF position, disconnect power to
battery charger, and remove battery cables (remove
negative lead first and reconnect it last) to disable
generator set before working on the generator set or
connected equipment. The generator set can be started
by an automatic transfer switch or remote start/stop
switch unless these precautions are followed.

ground the generator set and electrical circuits when in
use. Never contact electrical leads or appliances when
standing in water or on wet ground, as the chance of
electrocution is increased under such conditions.
Short circuits. Hazardous voltage can cause severe
injury or death. Short circuits can cause bodily injury
and/or equipment damage. Do not contact electrical
connections with tools or jewelry while adjustments are
made. Remove wristwatch, rings, and jewelry before
servicing equipment.
