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 10-1 for
location).

10.13Twelve-Lead Reconnection
The reconnection procedure that follows details voltage
reconnections only. If the generator set requires
frequency changes, adjust the governor and voltage
regulator. See the generator set service manual for
information regarding frequency adjustment.
In all cases, follow 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 start/stop switch to the STOP
position.
2. Disconnect engine starting battery, negative (--)
lead first. Disconnect power to battery charger, if
equipped.
3. Use Figure 10-5 to determine generator set
voltage configuration. Note original voltage and
reconnect as needed.
