7) Confirm that the cable thickness is as specified in the power sources
specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point there of fuse breaking,
disturbance to the normal function of a overload protection device.
• Proper starting power is not given to the compressor.
