3.2.5Electrical wiring

zDo not modify the electrical wiring. Incorrect wiring can cause an electrical shock and fire. Failure to do so will void any warranty.

zThe set value of the safety device must not be changed. Changing the set value can cause unit failure and fire.

zOnly qualified personnel are allowed to install wiring.

zBe sure to disconnect the power for safety. Wiring installation with the unit energized is strictly prohibitted.

zUse the specified cables. Properly apply strain relief to prevent an external force from being exerted on the terminals. Poor or loose connection can cause electrical shock, heat spots, or fire.

zSupply the power to the unit from a reliable power source (without surge or sag voltage).

zBe sure to use a GFCI breaker to prevent an electrical shock and burnt compressor motor. The breaker with adequate capacity of current leakage and load should be selected in accordance with “7.1 Standard Specifications”.

zEnsure that the power supply meets the specification of the unit.

zAlways establish a ground for safety.

zDo not connect the ground to a water line, gas pipe or lighting conductor.

zDo not branch off the wiring to make multiple circuits. Potential hot spots or fire may occur if disregarded.
