Electrical

DANGER: RISK OF ELECTROCUTION
▪ Turn OFF all power supply before removing the
switch box cover, connecting electrical wiring or
touching electrical parts.
▪ Disconnect the power supply for more than 1 minute,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing.
The voltage MUST be less than 50 V DC before you
can touch electrical components. For the location of the
terminals, see the wiring diagram.
▪ Do NOT touch electrical components with wet hands.
▪ Do NOT leave the unit unattended when the service
cover is removed.
WARNING
If NOT factory installed, a main switch or other means for
disconnection, having a contact separation in all poles
providing full disconnection under overvoltage category III
condition, shall be installed in the fixed wiring.
WARNING
▪ ONLY use copper wires.
▪ Make sure the field wiring complies with the applicable
legislation.
▪ All field wiring must be performed in accordance with
the wiring diagram supplied with the product.
▪ NEVER squeeze bundled cables and make sure they
do not come in contact with the piping and sharp
edges. Make sure no external pressure is applied to the
terminal connections.
▪ Make sure to install earth wiring. Do NOT earth the unit
to a utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.
▪ Make sure to use a dedicated power circuit. NEVER
use a power supply shared by another appliance.
▪ Make sure to install the required fuses or circuit
breakers.
▪ Make sure to install an earth leakage protector. Failure
to do so may cause electric shock or fire.
▪ When installing the earth leakage protector, make sure
it is compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.
Install power cables at least 1 metre away from televisions or radios
to prevent interference. Depending on the radio waves, a distance of
1 metre may not be sufficient.
WARNING
▪ After finishing the electrical work, confirm that each
electrical component and terminal inside the electrical
components box is connected securely.
▪ Make sure all covers are closed before starting up the
unit.
NOTICE
Only applicable if the power supply is three‑phase, and the
compressor has an ON/OFF starting method.
If there exists the possibility of reversed phase after a
momentary black out and the power goes on and off while
the product is operating, attach a reversed phase
protection circuit locally. Running the product in reversed
phase can break the compressor and other parts.
