11.1. Precautions on electrical wiring work

■

A main switch or other means for disconnection, having a
contact separation in all poles, must be incorporated in
the fixed wiring in accordance with the applicable
legislation.

■

Use only copper wires.

■

All field wiring must be carried out in accordance with the
wiring diagram supplied with the unit and the instructions
given below.

■

Never squeeze bundled cables and be sure that it does
not come in contact with the non-insulated piping and
sharp edges. Be sure no external pressure is applied to
the terminal connections.

■

Power supply wires must be attached securely.

■

If the power supply has a missing or wrong N-phase,
equipment will break down.

■

Be sure to establish an earth. Do not earth the unit to a
utility pipe, surge absorber, or telephone earth.
Incomplete earth may cause electrical shock.

■

Be sure to install an earth leakage protector in
accordance with the applicable legislation. Failure to do
so may cause electric shock or fire.

■

Be sure to use a dedicated power circuit, never use a
power supply shared by another appliance.

■

When installing the earth leakage protector be sure that
it is compatible with the inverter (resistant to high
frequency electric noise) to avoid unnecessary opening
of the earth leakage protector.

■

Be sure to install the required fuses or circuit breakers.

WARNING: Electrical installation

All field wiring and components must be installed by an
installer and must comply with the applicable legislation

DANGER: ELECTRICAL SHOCK

See 

"2. General safety precautions" on page 2

.

WARNING

CAUTION: Radio frequency interference

The equipment described in this manual may cause
electronic noise generated from radio-frequency energy.
The equipment complies to specifications that are
designed to provide reasonable protection against such
interference. However, there is no guarantee that
interference will not occur in a particular installation.

It is therefore recommended to install the equipment and
electric wires keeping proper distances away from stereo
equipment, personal computers, etc....

In extreme circumstances you shall keep distances of 3 m
or more and use conduit tubes for power and transmission
lines.
