5. ELECTRICAL CONNECTIONS
The ANL units are fully factory wired and only require
connection to the power supply network, downstream
of an isolator, in accordance with the applicable wiring
standards of the country of installation.
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 re-
quirements.
4. The power supply cable must have the appropria-
te 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 insulated
cables in accordance with applicable wiring stan-
dards.
MANDATORY REQUIREMENTS
1. A magneto-thermal circuit breaker conforming to
IEC-EN standards (contact aperture minimum 3 mm)
is required, with adequate protection in accordan-
ce with the data provided in the following table, to
be installed as close as possible to the unit.
2. An effective earth connection is required. The ma-
nufacturer cannot be held responsible for any da-
mages caused by lack of, or inadequate, earthing
of the unit.
3. For three phase units check the correct cable pha-
sing.
The cable cross sections shown in the following cable
are the recommended values based on a maximum 50
m cable length.
For longer cable lengths or different types of cable insta-
All electrical works must be carried out by
PERSONNEL WITH THE APPROPRIATE
LEGAL QUALIFICATIONS, trained and
aware of the risks relating to such works.
The design of the cabling and related
components must be carried out by PER-
SONNEL WITH APPROPRIATE QUALIFI-
CATIONS TO DESIGN ELECTRICAL INS-
TALLATIONS, following international and
national standards of the location the unit
is installed, in accordance with current le-
gal requirements.
For installation details refer to the electrical
wiring schematics supplied with the unit.
The electrical wiring schematic together
with the manuals must be conserved with
care and MADE AVAILABLE FOR FUTURE
REFERENCE.
The weatherproof seals of the equipment
must be checked before making electrical
connections and the unit most only be
powered on completion of all electrical
and hydraulic works.
WARNING
Using the water piping to earth the unit is
not permitted.
WARNING
Verify that all terminals are tight on power
carrying conductors before fi rst start-up
and 30 days after putting into service.
Afterwards check twice yearly.
Loose terminals can result in overheating
of cables and components..
