Note

When closing the unit the electrical component box cover, make sure 
that the sealing material on the lower back side of the cover is not 
caught and bend towards the inside.

8-3 Procedure for Incoming Wiring

• Route high-voltage wiring (power supply wiring, earth wires, and 

warning/alarm/operation wiring) through wiring openings located 
on the side or front of the unit (knock holes) or on the bottom frame 
(knock holes).

• Route low-voltage wiring (for remote operating switches) through 

wiring openings (knock holes) located on the front of the unit or 
through wiring intakes.

Note

• Open the knock holes with a hammer or the like.
• After knocking out the holes, we recommend you remove any burrs 

and paint them using the repair paint to prevent rusting.

• When passing electrical wiring through the knock holes, protect the 

wiring with a conduit or bushings, making sure not to damage the 
wiring.

• If small animals might enter the unit, block off any gaps (hatching 

parts) with material (field supply).

8-4 Procedure for Power Supply Wiring



Procedure for Power Supply Wiring



1 Power supply (3 phase 380~415)
2 Overcurrent circuit breaker (earth leakage circuit breaker), all pole 

disconnection switch

3 Earth wire
4 Power supply terminal block
5 Mount insulation sleeves
6 Fix the power supply wiring for phases L1, L2, L3, and N, respec-

tively, to the resin clamp.

7 Earth wire

Perform wiring so that the earth wire will not come in contact with 
lead wires of the compressor. Otherwise, noise generated may 
have a bad influence on other equipment.

8 Ground terminal
9

• When two wires are connected to a single terminal, connect 

them so that the rear sides of the crimp contacts face each 
other.

• Also, make sure the thinner wire is on top, securing the two 

wires simultaneously to the resin hook using a clamp.

Power circuit, safety device, and cable requirements (X1M~X4M 
terminal block)

• A power circuit (see the following table) must be provided for con-

nection of the unit. This circuit must be protected with the required 
safety devices, i.e. a main switch, a slow blow fuse on each phase 
and an earth leakage circuit breaker.

• When using residual current operated circuit breakers, be sure to 

use a high-speed type (1 second or less) 200 mA rated residual 
operating current.

• Use copper conductors only.
• Use insulated wire for the power cord.
• Select the power supply cable type and size in accordance with rel-

evant local and national regulations.

• Specifications for local wiring are in compliance with IEC60245.
• Use wire type H05VV when protected pipes are used.
• Use wire type H07RN-F when protected pipes are not used.
