Applies to: Cummins/Onan GGHE, Cummins/Onan GGHF, Cummins/Onan WSG-1068 engine
Before you start
- Reconfiguring to higher voltages can exceed winding voltage capability and damage generator
- Reconfiguring to lower voltages can increase line current beyond breaker rating
Procedure
- Check available generator output voltages and maximum current ratings on generator nameplate.
- Reconfigure generator output leads per Reconnection Diagram on control housing side access cover if required.
- Check stator lead terminal block connections and perform necessary reconnect to obtain required voltage.
- Route current transformers (CT1, CT2, CT3) per Reconnection Diagram, dot facing generator, current flowing into dot.
