8.12.3 200--240-Volt Configurations
The 200--240-volt configuration does not use a jumper
lead. If the unit was originally wired for straight 100--120
volt, 3-wire, remove the jumper lead (see Figure 8-18 for
location). See Figure 8-21.

8.13 Twelve-Lead Reconnection
The reconnection procedure following details voltage
reconnections only. If the generator set requires
frequency changes, adjust the governor.
The following information illustrates 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 to
change output phase or voltage. Refer to the following
procedure and connection schematics. Follow all safety
precautions at the front of this manual and in the text
during reconnection procedure.
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.
Twelve-Lead Reconnection Procedure
1. Move generator set master switch to OFF position.
2. Disconnect engine starting battery, negative (--)
lead first. Disconnect power to battery charger, if
equipped.
3. Use Figure 8-22 to determine generator set
voltage configuration. Note the original voltage
and reconnect the generator set as needed.
