7.5 Power Wiring Connection Procedure
Be sure to connect the power supply wiring to the power supply terminal block and hold it in place using the included
clamp as shown in the next figure.
1. Power supply (3N~50Hz 380-415V)
2. Earth leakage circuit breaker
3. Branch switch, Overcurrent breaker
4. Ground wire
5. Attach insulation sleeves
6. Power supply terminal block
7. Ground terminal
8. Clamp (1) (accessory)
The L1, L2, L3 and N phases of the power wiring should be secured separately to the hook using the included
clamp (1).
The ground wiring should be bound to the power wiring using the included clamp (1) to prevent outside force from
being applied to the terminal area.
Wire so that the ground wiring does not come into contact with the compressor lead wiring. If they touch, this may
have an adverse effect on other devices.
Caution
Be sure to use crimp-style terminal with insulating sleeves for connections. (See the figure below.)
For wiring, use the designated power wire and connect firmly, then secure to prevent outside pressure being
exerted on the terminal board.
Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small head will strip the
head and make proper tightening impossible.
Over-tightening the terminal screws may break them.
See the following table for the tightening torque of the terminal screws.
When pulling the ground wire out, wire it so that it comes through the cut out section of the cup washer. (See the
figure below.) An improper ground connection may prevent a good ground from being achieved.
