Wiring work

Electrical work

ffWiring work should be performed in accordance with related laws such as technical specification on electric installation or installation guide.

ffCopper cable should be used for wiring work and all the wirings or parts should be rated products. ffWiring work should be performed by a company certified by an electric power company. ffRefer to the circuit diagram attached to the outdoor unit for detailed wiring work.

ffWiring work should be performed after disconnecting main circuit breaker and Y-joint switch.

ffYou must perform ground working 3. (Grounding resistance value should be less than 100Ω.) When ELB is installed, protective grounding resistance value can be applied. (When the ELB 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. )

ffDo not connect the ground wire to the 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, there will be no grounding effect.

-- Ground wire of telephone and lightning rod: The electric potential of ground wire may rise abnormally when lightening strikes.

ffThe ELB for ground-fault protection should be combined with MCCB or fuse equipped load switch. In this case, you should use the one that has at least the same or larger fuse capacity or the rated current of MCCB.

ffUse the wires that comply with regulated specification and firmly connect to the terminal board. Then tighten it with the provided screws so that the terminal board (connecting cable locally procured, grounding terminal) cannot be moved by external force.

ffWhen connecting outdoor unit main power, be aware of the connection order for 3 phase (R, S, T, N). fIfyou install the heat pump system with a heater, install separate watt-hour meter.

-- If the common watt-hour meter is used with other products, you cannot measure the accurate electricity usage by the heater. Contact service center for further technical information on installing watt-hour meter.

ffStandard power cable length should be below 50m.

-- If the length has to be over 50m, contact service center.

ffFix a cable tube using a CD connector (wire conduit) and bushing at the knock-out hole of the outdoor unit.
