After the confirmation of the above conditions, prepare the wiring as follows:
1) As for the method of wiring, follow the circuit diagram posted on the inside of
control cover.
2) The screw which fasten the wiring in the casing of electrical fittings are liable to
come loose from vibrations to which the unit is subjected during the course of
transportation. Check them and make sure that they are all tightly fastened. (If
they are loose, it could cause burn-out of the wires.)
3) Confirm the specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the
rated voltage marked on the name plate.
6) Confirm that the cable thickness is as specified in the power source specifica-
tion.
(Particularly note the relation between the cable length and thickness.)
7) In a wet or moist area, always install an earth leakage circuit breaker.
8) The following would be caused by voltage drop.
• Vibration of a magnetic switch, which will damage the contact point, fuse breaking,
disturbance of the normal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the
fixed wiring and have an air gap contact separation of at least 3mm in each
active(phase) conductor.
