6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on
the name plate.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Do not install the leakage breaker in a place which is wet or moist.
Water or moist may cause short circuit.
