Wiring work
f
Wiring work should be performed in accordance with related laws such as ‘Technical specification on electric installation’,
‘Wiring regulations’ or ‘Installation manual’.
f
Copper cable should be used for wiring work and all the wires or parts should be rated products.
f
Wiring work should be performed by a company certified by an electric power company.
f
Refer to the circuit diagram attached to the outdoor unit for detailed wiring work.
f
Wiring work should be performed after disconnecting main circuit breaker and Y-joint switch.
f
You must perform grounding work .
(Grounding resistance value should be less than 100Ω.)
When ELCB is installed, protective grounding resistance value can be applied.
(When the ELCB is 100mA, 0.1sec, protective grounding resistance value should be less than 250Ω at a place where
electric danger is high and should be less than 500Ω at other places. )
f

f
Do not connect a heater to an outdoor unit and do not install a duct which you arbitrarily remodeled.
- Failure to do so may result in reduced capacity of an air conditioner, electric shock, and fire.
f
Do not connect the grounding wire to that of gas pipe, water pipe, lightning rod, or telephone.
- Gas pipe: If the gas leaks, explosion or ignition may occur.
- Water pipe: If rigid vinyl pipe is used, grounding effect will not work.
- Grounding wire and lightning rod of telephone: The electric potential of grounding wire may rise abnormally in the
falling of a thunderbolt.
f
The ELB for ground-fault protection only should be combined with MCCB or fuse equipped load breaker switch. In this
case, you should use the one that has at least the same or more capcity as fuse capacity or the rated current of MCCB.
f
Use the wires that comply with regulated specification and firmly connect to the terminal board. Then tighten it with the
screws provided so that the terminal board cannot be moved by external force. (The connecting cable and the grounding
terminal should be locally procured). When wiring, the connection cable shouldn’t be too tight.
f
Apply silicon at the end of CD pipe so that rainwater does not enter.
