Installing grounding wire

X

Grounding must be done by a qualiﬁed installer for your safety.

X

Use the grounding wire by referring to the speciﬁcation of the electric cable of the outdoor unit.

Grounding the power cable

X

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

X

Ground the power cable according to the following.

Installation place

Power condition

High humidity

Average humidity

Low humidity

Voltage of lower than 150V

Perform the grounding work

3.

Note 1)

Perform the grounding work 3 if

possible for your safety.

Note 2)

Voltage of higher than 150V

Must perform the grounding work 3.

Note 1)

(In case of installing circuit breaker as well)

1)

Grounding work 3

• Grounding must be done by your installation specialist.

• Check if the grounding resistance is lower than 100Ω. When installing a circuit breaker that can cut the electric

circuit within 0.5 second in case of a short circuit, the allowable grounding resistance should be 30~500Ω.

2)

Grounding at dry place

• The grounding resistance is should be lower than 100Ω. (It should not be higher than 250Ω)

- Use the rated grounding wire by referring to the speciﬁcation of the electric cable of the outdoor unit.

NOTE

Performing the grounding work

X

Use the grounding wire by referring to the speciﬁcation of the electric cable for the outdoor unit.

When using the terminal for grounding only

When using grounding of the switch board
