CAUTION
<To electrician>
• Do not operate the air conditioner until the refrigerant piping work is
completed.
(Operating the air conditioner before the refrigerant piping work is
completed may damage the compressor.)
• Install a ground fault circuit interrupter.
(The inverter is provided in the air conditioner. In order to prevent
malfunction of the ground fault circuit interrupter itself, use a breaker
resistant to higher harmonics.)
• Electricians having sufficient knowledge should perform the electri-
cal wiring work.
All wiring must comply with local electrical codes and National Elec-
trical Code (NEC).
• Perform the electric wiring work in accordance with the “wiring dia-
gram label”.
Make sure to turn OFF the branch switch and overcurrent breaker
before starting the work.
• Perform grounding to the indoor unit and outdoor unit.
• Use only copper wires.
• Make sure to turn the power off before starting the electric wiring
work.
Do not turn ON any switch until the work is completed.
• The outdoor unit has an inverter which generates noise and charges
the outer casing with the leakage current. The outdoor unit should be
grounded so that the effect of the generated noise on other equip-
ment can be reduced, and that the outer casing can be discharged.
• As this unit is equipped with an inverter, installing a phase advancing
capacitor will not only reduce the power factor improvement factor,
but may also cause the capacitor to overheat due to high-frequency
waves. Therefore, never install a phase advancing capacitor.
• Never push excessive electric wires into the units.
• Protect electric wires with conduit tubes or vinyl tubes so that they
will not be damaged by edges of knockout holes.
• Fix electric wires with clamps as accessories so that they will not
come to contact with pipes and stop valves.
(Refer to
“7-3 Power supply wiring connection procedure”
.)
7-1 Connection example of whole system wiring
7-2 Routing power supply wiring and transmission
wiring
Let the power supply wiring and transmission wiring with a conduit pass
through one of the knockout holes on the front or side piping 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 knockout holes
• Open the knockout holes with a hammer or the like.
• After knocking out the holes, we recommend you remove burrs in the
knockout holes and paint the edges and areas around the edges
using the repair paint to prevent rusting.
• When passing wiring through knockout holes, make sure there are
no burrs, and protect the wiring with protective tape.
CAUTION
• Use conduit for both the power supply wiring and transmission wiring.
• Outside the unit, make sure to keep the wirings 5 inch away.
Otherwise, the outdoor unit may be affected by electrical noise
(external noise), and malfunction or fail.
• Be sure to connect the power supply wiring to the terminal block and
secure it as described in “7-3 Power supply wiring connection procedure”.
• Fix the wiring between the units in accordance with “7-4 Transmis-
sion wiring connection procedure”.
• Secure the wirings with the clamps (accessory) so that do not touch
the piping.
• Make sure the wirings will not be pinched by the front panel, and
close the panel firmly.
• Route the conduit along the unit by using a elbow socket and so on
to prevent it from being stepped on.
