• N° 1 use and maintenance manual.
• N° 1 electrical drawing.
• N° 1 drilling layout.
• N° 2 probes NTC 10K 1%
MECHANICAL ASSEMBLY
 Each panel is conceived to be wall-mounted; please choose depending on the
weight a correct fixing method.
 Install the device in places where the protection rating is observed.
 To effect correct electrical connection and maintain the protection rating, use
appropriate cable glands and plugs to ensure a good seal
 Install the device at height allowing the installer an easier use and maintenance.
The installer must not be in danger when it’s working on the panel. Height must
be between 0,6 and 1,7 mt from the ground.

ELECTRICAL WIRINGS
 For the electrical wirings please refer to the wiring diagram and technical
characteristics of the panel model to be installed.
 Panel power supply must be on a dedicated line, and must be placed a
device suitable for protection against indirect contacts upstream the line
(differential interruptor).
 Do not fit power supply wiring and signal wiring (probes/sensors and
digital inputs) in the same raceways or ducts.
 Do not use multi-polar cables in which there are wires connected to
inductive/power loads or signalling wires (e.g. probes/sensors and digital
inputs).
 Minimise the length of connector wires so that wiring does not twist into a
spiral shape as this could have negative effects on the electronics.
 When it is necessary to make a probe/sensor extension, the wires must
have a cross-section of at least 1 mm
2
.
 All wiring must be of a cross-section suitable for relevant power levels.
Insulation degree must be compatible with the applied voltages.
Preferably use cables with insulator not propagating the flame and a low
toxic smoke emission if interested by fire.
 It is obligatory to connect clamp marked with PE abbreviation to the
ground of the supply system. If necessary, please verify ground system
efficiency.
 Do not connect to the PE clamp conductors different from the external
protection one.

FRONT PANEL CONNECTION
Hook front panel and reconnect the electronic card connector as indicated below.
Fig.12: Hook the frontal panel back up to the
lower part of the box by inserting the
two hinges in their seats.
Fig.13: Bend the hinges and rotate the front
panel downwards 180° to gain access
inside the panel and then reconnect
the electronic card connector.
.
Fig.13: In case panel is connected with
TeleNET or Alarm/Aux relay is used
wirings must be done directly on the
electronic card clamps.
It’s suggested to put that wirings
beside the connection cables from
electronic card and bottom of the box.

VERIFICATIONS BEFORE USE
 After doing the wirings, please verify using the wiring diagram on the
correct execution of the connections.
 Please check the correct screw clamping.
 Check, when possible, the correct functioning of the outside protection
devices.
 Please correctly calibrate the motor circuit breaker (if present) dedicated
to the compressor as indicated in the next chapter.
 After powering the electrical panel please check the correct current
absorption on the loads, and after few hours of functioning check the
good tightening of screws on terminal blocks (included power supply line
connection). Warning: before doing that it’s necessary to cut off power
sectioning power supply upstream the line and block it with a padlock for
max. safety. Before any operation verify with a tester the absence of
voltage.

COMPRESSOR MOTOR CIRCUIT BREAKER CALIBRATION
Below we show step by step how to correctly calibrate motor circuit breaker dedicated to the
compressor.
Fig.12: When the system is started for first
time it’s suggested to calibrate the
motor circuit breaker on the
compressor power circuits. Using an
ammeter verify the effective
absorption.
.
Fig.13: Make the motor circuit breaker
calibration basing on the measured
absorption. Any way the set up value
must not be higher than the one
expected by the compressor
manufacturer. Warning: a wrong
calibration may cause compressor
breakdown or bad intervention of the
motor circuit breaker.
Fig.14: To make the calibration use the
regulation screw on the front side of
motor circuit breaker.
