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.
