The characteristics of the electrical lines must be
determined by specialized personnel able to design
electrical installations; moreover, the lines must be in
conformity with regulations in force.
The protection devices of the unit power line must be
able to stop the presumed short circuit current, whose
value must be determined in function of system
features.
The power cables and the protection cable section must
be defined in accordance with the characteristics of the
protections adopted.
All electrical operations should be performed by trained
personnel having the necessary requirements by the
regulations in force and being informed about the risks
relevant to these activities.
Operate in compliance with safety regulations in force .
ELECTRICAL DATA
The serial number label reports the unit specific
electrical data, included any electrical accessories .
The electrical data indicated in the technical bulletin and
in the manual refer to the standard unit, accessories
excluded.
Refer to the electrical data report on the serial number
label
Refer to the electrical data report on the serial number

CONNECTIONS
Refer to the unit electrical diagram (the number of the
diagram is shown on the serial number label).
Verify that the network has characteristics conforming to
the data shown on the serial number label.
Before starting work, verify that the sectioning device at
the start of the unit power line is open, blocked and
equipped with cartel warning.
Primarily you have to realize the earthing connection
Shelter the cables using adequate measure fairleads.
Before power the unit, make sure that all the protections
that were removed during the electrical connection work
have been restored.
SIGNAL S/DATA LINES
Do not overpass the maximum power allowed, which
varies, according to the type of signal.
Lay the cables far from power cables or cables having a
different tension and that are able to emit
electromagnetic disturbances.
Do not lay the cable near devices which can generate
electromagnetic interferences.
Do not lay the cables parallel to other cables; cable
crossings are possible, only if laid at 90°.
Connect the screen to the ground, only if there aren’t
disturbances
Guarantee the continuity of the screen during the entire
extension of the cable.
Respect impendency, capacity and attenuation
indications.
Power input
Fix the cables: if vacated may be subject to tearing.
The cable must not touch the compressor and the
refrigerant piping (they reach high temparatures).
Remote ON-OFF
Do not perform short On Off cycles
Do not use the remote On Off with thermoregulation
function.termoregolazione.
