Precautions on electrical wiring work

Before obtaining access to terminal devices, all supply circuits
must be interrupted.

Use only copper wires.

The wiring between the indoor unit and outdoor unit must be for
220~240 V.

A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in the fixed
wiring in accordance with relevant local and national legislation.
Do not turn on the main switch until all the wiring is completed. 

Never squeeze bundled cables into a unit.

Fix cables so that cables do not make contact with the pipes
(especially on high pressure side).

Secure the electrical wiring with clamping material as shown in
the figure below so that it does not come in contact with the
piping, particularly on the high-pressure side.
Make sure no external pressure is applied to the terminal
connectors.

When installing the earth leakage breaker make sure that it is
compatible with the inverter (resistant to high frequency
electrical noise) to avoid unnecessary opening of the earth
leakage breaker.

As this unit is equipped with an inverter, installing a phase
advancing capacitor not only will deteriorate power factor
improvement effect, but also may cause capacitor abnormal
heating accident due to high-frequency waves. Therefore, never
install a phase advancing capacitor.

Secure the wiring in the order shown below.

1

Secure the ground wire to the stop valve attachment plate so
that it does not slide.

2

Secure the ground wire to the stop valve attachment plate one
more time along with the electric wiring and the inter-unit wiring.

Lay the electrical wiring so that the front cover does not rise up
when doing wiring work and attach the front cover securely.

When cables are routed from the unit, a protection sleeve for the
conduits (PG-insertions) can be inserted at the knock-out hole.

(See figure 7)

When you do not use a wire conduit, be sure to protect the wires
with vinyl tubes to prevent the edge of the knock-out hole from
cutting the wires.

Follow the electric wiring diagram for electrical wiring works.

Form the wires and fix the cover firmly so that the cover may be
fit in properly.

All field wiring and components must be installed by a
licensed electrician and must comply with relevant
European and national regulations.

All components procured on the site and all electric
construction should comply with the applicable local
and national codes.

High voltage
To avoid electrical shock, make sure to disconnect the
power supply 1 minute or more before servicing the
electrical parts. Even after 1 minute, always measure
the voltage at the terminals of main circuit capacitors
or electrical parts and, before touching, make sure
that those voltages are 50 V DC or less.

To persons in charge of electrical wiring work:

Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
