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, MUST 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
electrical 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: connect the earth cable first, before making
the current-carrying connections.
▪
When disconnecting the power supply: disconnect the current-carrying cables
first, before separating the earth connection.
▪
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.
