must be carried out exclusively by authorised service centres or other qualified centres. The earth
wire of the power supply cable of the compressor must be connected only and exclusively to the
PE pin of the terminal board of the actual compressor. Before replacing the plug of the power
supply cable ensure that the earth wire is connected.
EXTENSION CABLE
Use only extension cables with plug and earth connection. Never use damaged or squashed
extension cables. Ensure that the extension cable is in a good state of wear. When using an
extension cable, ensure that the cross section of the cable is sufficient to convey the current
absorbed by the product to be connected.
If the extension cable is too thin there could be drops in voltage and therefore loss in power and
overheating of the equipment.
The extension cable of the three-phase compressors must have a cross section in proportion with
its length: see table below:

Avoid all risks of electrical shocks. Never use the compressor with damaged
electrical cables or extension cables. Regularly check the electrical cables.
Never use the compressor in or near water or near a hazardous area where
electrical shocks may be encountered
ELECTRICAL CONNECTION
The three-phase compressors must be installed by a qualified engineer. The three-phase
compressors are supplied with cable (1) but without plug.
It is advisable to install the connector, magneto thermal switch and fuses near the
compressor (3 m away at the most). The magneto thermal switch and the fuses must have
the characteristics indicated in the table below:
