3.4 Connection to the compressed airline
Provide the throughput capacity of the compressed-air line in accordance with the perfor- mance of
the compressor. In order to avoid damage associated with seal failure of the compressed-air line, the
compressor should be connected via a flexible hose. All components of the compressed-air line must
have a working pressure no less than the compressor's nominal pressure. Use a pressure vessel with a
capacity corresponding to the compressor's performance and the compressed air consumer.
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
The power cable has to be fed into the compressor.
Fig. 3.5.1 Power cable connection
Remove the left side panel, pass the cable under the compressor into the orifice (1) and
ble gland (2). Connect the power supply cables to the terminal 4. The earth wire of the power
cable must be connected to the corresponding earthing bolt 3.

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