Connecting Cables

General consideration
Followings should be considered before beginning unit wiring.
• Field-supplied electrical components such as power switches, circuit breakers, wires, terminal
boxes, etc should be properly chosen with compliance with national electrical legislation or
regulation.
• Make it sure that supplied electricity is enough to operate the unit, water tank heater, etc. The
capacity of fuse also selected according to the power consumption.
• The main electricity supply should be dedicated line. Sharing main electricity supply with other
devices such as washing machine or vacuum cleaner is not permitted.
CAUTION
• Before starting wiring job, the main electricity supply should be turned off until wiring is completed.
• When adjusting or changing wiring, the main electricity supply should be turned off and ground wire
should be connected securely.
• Installation place should be free from the attack of wild animal. For example, mice's wire attacking or
frog's entering into the unit may cause critical electrical accident.
• All power connections should be protected from dew condensation by thermal insulation.
• All electrical wiring should comply with national or local electrical legislation or regulation.
• The ground should be connected exactly. Do not earth the unit to the copper pipe, steel fence at the
veranda, city water outlet pipe, or any other conductivity materials.
• Fix all cable using cord clamp tightly. (When cable is not fixed with cord clamp, use additionally
supplied cable ties.)
