Page 9: Electric Wiring
Electric Wiring Conduct electric wiring according to the local wiring standard. 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.
Page 10 Mounting a circuit breaker The Oil Cooling Unit is not equipped with a circuit breaker. Be sure to mount a 3-pole circuit breaker exclusively for the Oil 12·13 Cooling Unit to the main machine. For the breaker capacity, refer to the specifications of each model (see page To ensure safety, it is recommended to use an earth leakage breaker.
