Connecting the unit

ATTENTION
Before connecting the unit make sure that mains voltage and frequency correspond to
the values shown in the data plate. Voltage tolerance: +/- 10% compared to nominal
value.

7.1 Electric connection

Connect the unit after checking the panel components.
ATTENTION
Connection to the electric line shall be effected applying a suitable safety device (a circuit
breaker or a ground fault interrupter) selected by the installer on the basis of the line
involved and of the absorption indicated on the unit plate.
If a cold room includes more units, each unit shall be provided with its own safety device.
We advise to install a microswitch (not supplied) on the cold room door which will
- switch on the light in the cold room, stop the unit and
- override the temperature alarm (for about one hour after door closing)
every time the door is opened.
The necessary cable is available with the unit. Connect it keeping in mind the following:
microswitch closed = door closed.
ATTENTION
Above microswitch is not supplied with the unit. If the microdoor cable is disconnected
or damaged, the same conditions will occur as in case of open door and connected
microdoor.
Connect the unit paying attention to the colours of the supply cable wires:
a) 230V/1/50-60Hz
b) 230V/3/50-60Hz
c) 400/3/50 Hz
