The unit is completely pre-wired at the
factory. The electrical power require-
ments are specified on a data plate.
The power line should be fitted with
appropriate protective devices.
Cable sections and dimensions of the
line switch are indicative only.
The installation technician is respon-
sible for dimensioning the power line
as appropriate, in relation to its length,
the cable type, unit absorption and
position.
All electrical connections should com-
ply with standing regulations at the
time of the installation of the unit.
N.B
:
Check that all power conductor
terminals are tightened at the first star-
ting and after 30 days from start-up.
Afterwards, check the tightening of all
power conductor terminals every six
months. Loosen terminals may determi-
ne an overheating of cables and com-
ponents.
