3.5 Connecting to power supply
The compressor is not supplied with a power cable.
The cable size must be chosen to ensure that the maximum voltage drop not exceed 5 % of
the nominal voltage value. Cable length must not exceed 25 m. Ambient temperature in the
facility must not exceed 40°C.
The cable must be sheathed with a fire retardant compound.
An isolating switch must be fitted within reach of the compressor to facilitate connection
and maintenance.
The power cable has to be fed into the compressor.

The compressor must be earthed and protected against short
cir- cuits in each phase, impermissible voltage fluctuation and
phase failure.
