Connecting the unit

ATTEN TI ON
Before connecting the unit make sure that m ains voltage and frequency correspond to
the values show n in the data plate. Voltage tolerance: +/ - 10% compared to nominal
value.

7.1 Electric connection

Connect the unit after checking the panel components.
ATTEN TI ON
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.
When choosing the protective device take the following into consideration: should the
current
at installation point be higher than 10 KA, install a limiting device which reduces its peak value to 17 KA.
Prospective short-circuit current (Ik)
provided that no protective device against overcurrent has been installed on the circuit.
Peak value:
max value of prospective short-circuit current.
Connect the unit paying attention to the colours of the supply cable wires:
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.
