9.1 Voltage Reconnection
9.1.1 Introduction
Use the following voltage reconnection procedure to
change the voltage of 12-lead generator sets.
See
Generator Set Frequency Change and Adjustment later
in this section for frequency adjustment information.
Refer to 9.1.2, Voltage Reconnection Procedure and the
connection schematics. Follow the safety precautions
at the front of this manual and in the procedure text and
observe National Electrical Code (NEC) guidelines.
NOTICE
Voltage reconnection. Affix a notice to the generator set
after reconnecting the set to a voltage different from the
voltage on the nameplate. Order voltage reconnection
decal 246242 from an authorized service distributor/
dealer
.
NOTICE
This generator set has been
rewired from its nameplate voltage
to
246242
Note: Equipment damage. Verify that the voltage
ratings of the transfer switch, line circuit breakers,
and other accessories match the desired line
voltage.
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
are in place.
Moving rotor.
WARNING
Grounding electrical equipment. Hazardous voltage can
cause severe injury or death.
Electrocution is possible
whenever electricity is present. Open the main circuit
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.
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.

9.1.2 Voltage Reconnection Procedure
1. Place the generator set master switch in the
OFF/RESET position.
2. Disconnect the generator set engine starting
battery, negative (--) lead first. Disconnect power to
the battery charger (if equipped).
3. Use Figure 9-20 or Figure 9-21 to determine the
generator set voltage configuration. Note the
original voltage and reconnect as needed. Route
leads through current transformers (CTs) and
connect them according to the diagram for desired
phase and voltage.
