Страница: 16 / 45

General
•
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.
•
Please refer to the "Information" section for the detailed
characteristics of the apparatus (dimensioning,
performance, etc) .
•
Operate in compliance with safety regulations in force .
•
Use single protection devices : gloves, glasses ecc….
•
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.
•
The electrical data indicated in the technical bulletin and in
the manual refer to the standard unit, accessories
excluded.
The serial number label reports the unit specific electrical
data, included any electrical accessories.
Refer therefore to the electrical data indicated on the
serial number label.
Connections
•
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.
•
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 .
•
Shelter the cables using adequate measure fairleads.
•
Before starting work, verify that the sectioning device at
the start of the unit power line is open, blocked and
equipped with sign warning.
•
First create the earthing connection.
•
Prior to powering the unit ensure that all the protections
that were removed during the electrical connection work
have been restored.
Signal lines/data-lay
•
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 for the entire
extension of the cable.
•
Respect impendency, capacity and attenuation indications.

6.1 PRELIMINARY INFORMATION
6.2 POWER SUPPLY INPUT
Fix the cables: if vacated may be subject to tearing.
The cable don't have to touch the compressor and the
refrigerant piping ( they reach high temparatures ).
