6. FIELD WIRING
CAUTION
To the electrician
• Do not operate until refrigerant piping work is completed.
(If operated before complete the piping work, the compressor may
be broken down.)
• Be sure to install a ground fault circuit interrupter.
(This unit uses an inverter, so install the ground fault circuit inter-
rupter that be capable of handling high harmonics in order to pre-
vent malfunctioning of the ground fault circuit interrupter itself.)
6-1 Wiring connection example for whole system
• Electrical wiring work should be done by a certified professional.
• Follow the “Electrical wiring diagram face plate” when carrying out
any electrical wiring.
Only proceed with wiring work after blocking off all power.
• Make sure the ground resistance is no greater than 4Ω .
• Attach a ground fault circuit interrupter.
• Ground the indoor and outdoor units.
• Do not connect the ground wire to gas pipes, sewage pipes, lightning
rods, or telephone ground wires.
• Gas pipes: can explode or catch fire if there is a gas leak.
• Sewage pipes: no grounding effect is possible if hard plastic pip-
ing is used.
• Telephone ground wires and lightning rods: dangerous when
struck by lightning due to abnormal rise in electrical potential in the
grounding.
• Use copper wire.
• When doing the electrical wiring, always shut off the power source
before working, and do not turn on the switch until all work is com-
plete.
• This unit has an inverter, so it must be grounded in order to reduce
noise and prevent it affecting other appliances, and also to release
any electrical build-up in the unit case due to leaked current.
• Do not install a power-factor improving phase-advancing capacitor
under any circumstances.
(Not only will this not improve the power factor, but it might cause a
fire.)
• Connect the wire securely using designated wire and fix it with
attached clamp without applying external pressure on the terminal
parts (terminal for power wiring, terminal for transmission wiring and
earth terminal). See “6-3 How to connect the power supply wir-
ing”.
• Left-over wiring should not be wrapped and stuffed into the unit.
• To prevent the power wiring from being damaged by the knock hole
edges, put it in a wiring pipe or plastic tube to protect it.
• Secure the wiring with the included clamp so that it does not come in
contact with the piping or shutoff valve.
(See “6-3 How to connect the power supply wiring”.)
CAUTION
• Use a power wire pipe for the power supply wiring.
• Outside the unit, make sure the weak electric wiring (i.e. for the
remote controller cord, between units, etc.) and the strong electric
wiring do not pass near each other, keeping them at least 2in.
apart.
Proximity may cause electrical interference, malfunctions, and
breakage.
• Be sure to connect the power wiring to the power wiring terminal
block and secure it as described in “6-3 How to connect the
power supply wiring”.
• Transmission wiring should be secured as described in “6-4 Trans-
mission wiring connection procedure”.
• Secure wiring with clamp (accessory) to avoid contact with piping.
• Make sure the wiring and the front panel do not stick up above the
structure, and close the cover firmly.

6-2 How to lay the power supply wiring and trans-
mission wiring
Let the power supply wiring and transmission wiring with a conduit pass
through one of the knockout holes on the front or side cover, and let the
transmission wiring with a conduit pass through another knockout hole.
• For protection from uninsulated live parts, thread the power supply
wiring and the transmission wiring through the included insulation
tube and secure it with the included clamp.
Precautions knock out holes
• Open the knock holes with a hammer or the like.
• After knocking out the holes, we recommend you remove burrs in the
knock holes and paint the edges and areas around the edges using
the repair paint to prevent rusting.
• When passing wiring through knock holes, make sure there are no
burrs, and protect the wiring with protective tape.
