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
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.
∗ The distance between the contacts of the circuit breaker must be more than 3 mm.
To use an earth leakage breaker, select an inverter-compatible type.
If the earth leakage breaker is not inverter-compatible, it may malfunction due to high-frequency noise of the
inverter. (Recommended product: 15 mA or 20 mA)

When using the different-voltage model (-047, -048),
insert the power cable into the transformer box.
∗ Use conduits with IP54 or higher for wiring intake to allow the electric
component box to have a protective structure equivalent to IP54.
If the electric component box is affected by electrical noise, use
conduits or shielded cables. Allow a proper distance from the
potential noise source.
Use green/yellow ground cable.
Connect the power cable to the breaker if OILCON is supplied
with breaker.
When you remove the power cables, follow the instructions above in reverse.
(Default setting is breaker OFF.)
The cable size should conform to those listed below, or a larger size.
Cable type
AKZ149/329/439 series
JIS Heat-resistant vinyl, 2.0 mm
UL cable
UL1015 AWG#14 (equivalent to 2.0 mm
2.5 mm
For each wiring, use M4 (M5 for the terminal with a breaker) coated
round crimp-style terminal. (For the crimp tool, use the specified tool.
Carry out the processing of the crimp-style terminal to prevent short-
circuits between phases.)
The tightening torque of the screw to the terminal block should be
0.98 to 1.47N·m.
Carry out the processing of the wiring carefully not to damage the
electric wire coating.
Fix the electric wire and the signal wire to the anchor mount with tie

wrap. (See page )
