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 specification.
(Particularly note the relation between cable length and thickness.
7
Do not install an earth leakage circuit breaker in a wet or moist area.
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 3 mm in each active(phase) conductors.
