Kohler 13EFOZ/15.5EOZ, 8.5EFOZ manual Twelve-Lead Reconnection, 3 200--240-Volt Configurations

8.1.3200--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 8-1 for location).

8.2 Twelve-Lead Reconnection

The reconnection procedure 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.

The following information illustrates the reconnection of twelve-lead generator sets. In all cases, conform to the National Electrical Code (NEC).

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 the 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.Place the generator start/stop switch in the STOP position.

2.Disconnect generator set engine starting battery, negative (--) lead first.

3.Disconnect power to battery charger, if equipped.

4.Use Figure 8-5 to determine the generator set voltage configuration. Note the original voltage and reconnect the generator set as needed. Route leads through current transformers (CTs) and connect the leads according to the diagram for the desired phase and voltage.

EM-250000-E

Note: Current Transformers (CTs) are not used on all sets. CT dot or “HI” toward generator.
