Section 3 Generator Reconnection
3.1 Voltage Reconnection
The reconnection procedure explains voltage
reconnections only. Do not attempt to change the
frequency (e.g. from 60 Hz to 50 Hz) in the field.
The following instructions explain the reconnection of
12-lead generator sets. In all cases, follow the National
Electrical Code (NEC) guidelines.
Reconnect the stator leads of the generator set if a
different output phase or voltage is desired. 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 and
affix decal to generator set after reconnecting to a
voltage different than the nameplate.
NOTICE
This generator set has been
rewired fr om its nameplate voltage
to
246242
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery charger.
(3) Remove the battery cables, negative (--) lead first.
Reconnect the negative (--) lead last when reconnecting the
battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
areinplace.
Moving parts.
WARNING
Grounding electrical equipment. Hazardous voltage can
cause severe injury or death. Electrocution is possible
whenever electricity is present. Ensure you comply with all
applicable codes and standards. Electrically ground the
generator set, transfer switch, and related equipment and
electrical circuits. Turn off the main circuit breakers of all
power sources before servicing the equipment. Never contact
electrical leads or appliances when standing in water or on wet
ground because these conditions increase the risk of
electrocution.
Short circuits. Hazardous voltage/current 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 making adjustments or
repairs. Remove all jewelry before servicing the equipment.
