Section 5. Voltage Reconnection
5.1 Introduction
Use the following voltage reconnection procedure to change the voltage of 10- and 12- lead generator sets. Frequency changes
require voltage regulator
and governor adjustments. Refer to the respective spec sheet to determine if frequency is fixed or field-
convertible. If frequency is adjustable, refer to the engine service manual and/or governor literature for conversion information.
Refer to the following 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.
Note :
Equipment damage. Verify that the voltage ratings of the transfer switch, line circuit breakers, and other accessories match the
selected line voltage.
WARNING
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.
Disabling the generator set. Accidental starting can cause severe injury or death. Before working on the generator set or
equipment connected to the set, disable the generator set as follows: (1) Press the generator set off/reset button to shut down
the generator set. (2) Disconnect the power to the battery charger, if equipped. (3) Remove the battery cables, negative (
–) lead
first. Reconnect the negative (
–) lead last when reconnecting the battery. Follow these precautions to prevent the starting of the
generator set by the remote start/stop switch.
DANGER
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when all guards and electrical enclosures are in place.
Grounding electrical equipment. Hazardous voltage will 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 will 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.
