ESIE13-02A
1.5.6 Electrical
Install power cables at least 1 meter away from televisions or radios to prevent interference.
Depending on the radio waves, a distance of 1 meter may not be sufficient.
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 cate-
gory III condition, shall be installed in the fixed wiring.
WARNING
ONLY use copper wires.
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.
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.
