ELECTRICAL CONNECTIONS
The ANL units are fully factory wired and only require
of an isolator, in accordance with the applicable wiring
It is recommended to check the following items:
1.
The electrical network is capable of meeting the
electrical input data shown in the table below.
2.
The unit is only powered up on completion of
any hydraulic and electrical works.
3.
Comply with the indicated phasing and earth
requirements.
4.
The power supply cable must have the appropri-
ate protection against short circuits, residual
current and earth leakage with suitable isolation
from other devices.
5.
The tolerance on the power supply voltage is
±10% of the nominal voltage rating of the unit
(for three phase units a maximum imbalance of
3% between phases is permitted). If these values
are not met please contact the power supply
company.
6.
For the electrical connections use double insu-
lated cables in accordance with applicable wiring
standards.
1.
A magneto-thermal circuit breaker conforming
to IEC-EN standards (contact aperture minimum
3 mm) is required, with adequate protection in
accordance with the data provided in the follow-
ing table, to be installed as close as possible to
the unit.
2.
An effective earth connection is required. The
manufacturer cannot be held responsible for
any damages caused by lack of, or inadequate,
earthing of the unit.
3.
For three phase units check the correct cable
phasing.
The cable cross sections shown in the following cable
are the recommended values based on a maximum 50
m cable length.

WARNING
Verify that all terminals are tight
on power carrying conductors be-
fore first start-up and 30 days after
putting into service. Afterwards
check twice yearly.
Loose terminals can result in
overheating of cables and com-
