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.
CAUTION
When connecting the power supply, the earth connection
must be made before the current-carrying connections are
established. When disconnecting the power supply, the
current-carrying connections must be separated before the
earth connection is. The length of the conductors between
the power supply stress relief and the terminal block itself
must be as such that the current-carrying wires are
tautened before the earth wire is in case the power supply
is pulled loose from the stress relief.
NOTICE
Precautions when laying power wiring:
▪ Do NOT connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
cause abnormal heat).
▪ When connecting wiring which is the same thickness,
do as shown in the figure above.
▪ For wiring, use the designated power wire and connect
firmly, then secure to prevent outside pressure being
exerted on the terminal board.
▪ Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
damage the head and make proper tightening
impossible.
▪ Over-tightening the terminal screws may break them.
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.
