ELECTRICAL POWER CONNECTIONS
For the functional connection of the unit, bring the power
supply cable to the electrical panel inside the unit and con-
nect it to the terminals, respecting the U-V-W as phases, N
as neutral and PE as earth.
AUXILIARY CONNECTIONS
All the terminals referred to in the following explanations
are to be found on the terminal board located inside the
electrical panel and called "installer terminals".
REMOTE START UP AND SHUT DOWN
To use a remote on/off device, the jumper must be
replaced with a switch connected to terminals 6 and 7 on
the installer terminal board. For timed operation, connect
a daily or weekly timer between terminals 6 and 7.
REMOTE DEFROSTING ALARM
For the remote display of defrosting function of the unit, an
audible or visual alarm warning device can be connected
between terminals 12 e 13. Connect the phase to the ter-
minal 13 and the alarm signalling device between terminal
12 and neutral (max load 1A with 230V).
COMPRESSOR ON INDICATOR
For remote display of compressor operation, an audible or
visual alarm warning device can be connected between ter-
minals 21 and 22. Connect the phase to terminal 22 and
the alarm display device between terminals 21 and the
neutral.

REMOTE ALARM
For the remote display of unit lockout due to malfunctions,
an audible or visual alarm warning device can be connected
between terminals 10 and 11. Connect the phase to the
terminal 11 and the alarm signalling device between termi-
nal 10 and neutral (max load 1A with 230V).
REMOTE KEYBOARD KIT
The remote keyboard kit can be used to verify all unit
functions and access electronic board parameters from a
point located at some distance from the unit itself. It con-
sists of a remote control module and a transformer.
To install the kit, proceed as follows:
- disconnect the power supply by means of the QS1 door
lock disconnecting switch then access the inside of the
electrical panel.
- connect the remote control module with 3 wires to ter-
minals 18, 19 and 20 of the installer terminal board;
terminal 18 should be connected to terminal 26 of the module;
terminal 19 should be connected to terminal 24 of the module;
terminal 20 should be connected to terminal 25 of the module;
To avoid disturbance caused by magnetic
fields, use of screened cable is recommended. The
cable should not exceed a maximum length of 100 m.
