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)
CAUTION
Remove the top plate mounting screws, and
remove the top plate.
1. Insert the power cable into the power cable
insertion hole (
φ
28) in the side plate of the unit.
When using the different-voltage model (-047, -048),
insert the power cable into the transformer box.
2. Insert the remote control signal cable and
external output signal cable into the signal cable
insertion hole (
φ
22) in the side plate of the unit.
When using the different-voltage model (-047, -048),
insert the power cable into the transformer box.
1. Connect the ground cable to the (ground) terminal.
Use green/yellow ground cable.
2. Connect the power cable to the power supply terminal block.
Connect the power cable to the breaker if OILCON is supplied
with breaker.
„
Secure the top plate attachment screw with 1N·m to maintain the
protection structure of the electric component box.

„
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 )
„
For remote control input connecting procedure, refer to page .
„
For external output contact connecting procedure, refer to page .
∗
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.
Re-mount the top plate, and fasten it with the
screws.
∗
The distance between the contacts of the circuit breaker must be more than 3 mm.
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.
