5.2.1 Procedure for Power Supply Wiring
¢ Procedure for Power Supply Wiring ²
1 Power supply (3
φ
380~415)
2 Branch switch or overcurrent circuit breaker
(earth leakage circuit breaker)
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, respectively, with the provided clamp (1) to
the resin clamp.
7 Fix the earth wire to the power supply wire (phase
N) with the provided clamp (1).
8 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.
9 Ground terminal
10 • 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 the accessory clamp (1).
Power circuit, safety device, and cable requirements
„
A power circuit (see the following table) must be provided for connection 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) 200mA 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 relevant 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.
