equipment box ” (page ).
For inside of the transformer
box, refer to the transformer
power supply terminal block in

Different-voltage model (–E)
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 (–E),
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.
Connect the power cable to the power supply
terminal block. Connect the ground cable to the
PE (ground) terminal.

∗
When inserting each cable from the left side of the unit (when viewed
from the front of the unit), place the cable along the guide rail in the
electrical equipment box. Then, fasten the cable to the cable anchor
at the bottom of the electrical equipment box by using a tie band etc.
Re-mount the top plate, and fasten it with the
screws.
∗
Mount a circuit breaker exclusively for the Oil Cooling Unit.
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.
