SPECIAL WARNINGS FOR 12-24Vcc 100-240Vca REFRIGERATORS
ELECTRICAL CONNECTION
We recommend connecting 12 or 24 V DC power lines directly to the battery,
following the corresponding instructions for the Danfoss compressor supplied (see
p. 32 and p.33)
.
Prepare the V AC power supply line using a three-pole cable with a minimum section
per conductor of 1 sq mm, suitable insulation for the intended use and environment and
compliant with the standards in force.
Connect the V AC power line using a plug/socket connection with suitable capacity
compliant with the standards in force. Alternatively, it is possible to fit an omnipolar
differential thermomagnetic circuit breaker with a capacity of 6 amperes and contact
opening of at least 3 mm or in any case, compliant with the standards in force.
When installation is complete, check the continuity of the earth circuit and perform all
of the electrical safety tests foreseen by the standards in force.
Protect the cables and lock them into place sufficiently to prevent them from
disconnecting if accidentally pulled or from coming into contact with hot parts at
temperatures above 50°C or with sharp parts.
Power line installation should be performed by qualified technical personnel who
can check the compliance of the system with standards in force and issue the
relevant conformity certification.
Connecting power to the internal light on 12/24V DC refrigerators with remote
motor:
Connect the optional cable (Code R10777 ) for inside light connection from the
terminal board on the back of the refrigerator and to the control unit of the
compressor, following the diagram on figure 15. (The terminal board is not
polarised and therefore, the connection can be made without distinction.)
