The reconnection procedure explains voltage
reconnections only. Adjust the governor and voltage
regulator at the time of frequency adjustment.
The following information illustrates the reconnection of
4-lead generator sets. In all cases, follow the National
Electrical Code (NEC) requirements.
Refer to the following procedure and the connection
schematics.
Follow all the safety precautions and
instructions at the beginning of this manual and in the
text
below while performing the reconnection
procedure.

affix the decal to the generator set after
reconnecting to a voltage different from the
nameplate.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working
on the generator set.

breakers of all power sources before servicing the equipment.
Configure the installation to electrically ground the generator
set, transfer switch, and related equipment and electrical
circuits to comply with applicable codes and standards. Never
contact electrical leads or appliances when standing in water
or on wet ground because these conditions increase the risk of
electrocution.

severe injury or death. Short circuits can cause bodily injury
and/or equipment damage . Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
