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) 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. 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.
7.1 Voltage Reconnection
The following instructions explain the reconnection of 12-lead generator sets to a different voltage configuration.
Only trained and qualified personnel should perform the reconnection procedure. 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. 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 from an authorized dealer and affix decal to generator set after reconnecting to a
voltage different than the nameplate.
