Grounding work

Installing grounding wire

•Grounding must be done by a qualified installer for you safety.

•Use the grouding wire by referring to the specification of the electric cable of the outdoor unit. 1 Grounding the power cable

––The standard of grounding may vary according to the rated voltage and installation place of the air conditioner.

––Ground the power cable according to the following.

Power condition	Voltage to ground is lower than	Voltage to ground is over
Installation place	150V	150V
High humidity	Must perform the grounding work 3. Note 1)
	(Including the case where earth leakage breaker is installed)
Average humidity	Perform grounding work 3. Note 1)	Must perform the grounding
		work 3. Note 1)
		(Including the case where
	Perform grounding work 3, if
Low humidity		earth leakage breaker is
	possible, for your safety. Note 2)
		installed)

Note 1) Grounding Work 3

––Grounding work must be done by an expert (with qualification).

––Check if the grounding resistance is lower than 100Ω. When installing a earth leakage breaker (that can cut the electric circuit within 0.5 second in case of a short circuit), allowable grounding resistance should be 30~500Ω.

Note 2) Perform ground work in a dry place

––The grounding resistance should be lower than 100Ω. Even in worst case, grounding resistance should be lower than 250Ω.
