Electric Wiring
Conduct electric wiring according to the local wiring standard.
For the power supply, be sure to use the commercial power source. If you use the inverter power source or other power source,
the product may cause burnout.
The Oil Cooling Unit (except for the “–B” model) is not equipped with a circuit breaker. A circuit breaker exclusively for the unit
should be mounted to the main machine.
For electric wiring, refer to the electric wiring diagram on the nameplate attached to the rear of the electrical equipment box cover.
Do not change the wiring in the Oil Cooling Unit. Do not touch the protection devices.
To turn ON the power supply for the Oil Cooling Unit, the following three methods are available:
When the circuit breaker for the main machine is turned ON, the Oil Cooling Unit starts operation. To stop the unit, turn
OFF the circuit breaker for the main machine.
