ELECTRICAL CONNECTIONS

DANGER!
Always install a general automatic switch in a
protected area near the appliance with a
characteristic delayed curve, sufficient capacity and
breaking power. There should be a minimum
distance of 3 mm between the contacts.
Earth connection is compulsory by law and
safeguards the user while the machine is in use.
DANGER!
Electrical connection of the unit must be carried out
by personnel skilled in the matter and in
compliance with the regulations in effect in the
country where the unit is installed. Non-conforming
electrical connection relieves
responsibility for damage to persons and property.
In making the electrical connections to the board,
cables must be routed so that they do not touch the
hot parts of the machine (compressor, flow pipe
and liquid line). Protect the wires from any foam.
IMPORTANT!
For electrical connections to the unit and the
accessories, follow the wiring diagrams which are
supplied with them.
The safety door interlock automatically prevents electric power being
fed to the unit if the cover panel over the electrical panel is opened.
After opening the front panel of the unit, feed the supply cables through
the appropriate cable clamps in the external panelling and then through
the cable clamps at the base of the electrical board.
The electrical power supplied by the single-phase or three-phase line,
must be taken to the main isolator switch.
The supply cable must be of the flexible type, with polychloroprene
sheathing of no lighter than H05RN-F: for the section, refer to the table
below or the wiring diagram.
117 mm
124 mm
130 mm
The earth conductor must be longer than the other conductors in order
to ensure that in the event of the cable clamping device becoming
slack, it will be the last to come under strain.
II.6.1.1 Remote management using connections set
up by the installer
The connections between board and switch or remote light must be
made with screened cable consisting of 2 twisted 0.5 mm² wires and the
screening. The screening must be connected to the earth screw on the
panel (on one side only). The maximum permitted distance is 30 m.

II.6.1.2 Remote management using accessories
supplied separately
It is possible to remote control the entire machine by linking a second
keyboard to the one built into the machine (KTR accessory).
In this case, unplug the unit control panel telephone lead from the unit
electronic board housing and plug in the remote control lead in its place.
To select the remote control system, consult paragraph II.2. The use
and installation of the remote control systems are described in the
Instruction Sheets provided with the same.
