2.2.6 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, 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.
