HARNESS AS-CONSOLE 3534449 - Caterpillar

Never disconnect current transformers from the Generator Set Load Sensor when the engine is running. The current transformers can develop very high voltages when open circuited with the unit loaded. This can result in serious injury or death to personnel.
Note: Terminals 4 through 9 of the generator set load sensor are the input terminals from the current transformers.
All current transformer lead ends must be connected to the Generator Set Load Sensor, or be taped as noted. If load is applied to the generator with leads not fastened together after they are disconnected from the Generator Load Sensor, extremely high voltages will be generated at lead ends. This can result in serious injury or death to personnel.
Note: The CT leads can be taped together as follows: CT4 to CT5, CT6 to CT7, CT8 to CT9.
Disconnect phase B CT input leads from T6 and T7. Tape these two lead ends together.
Disconnect phase C CT input leads from T8 and T9. Tape these two lead ends together.
Connect phase A CT input leads to T4 and T5.
Determine the phasing for phase A
