Comprag AV5510 [16/96] Connection to the compressed airline

Version 1.4

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 exible 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 re retardant compound. An isolating switch must be tted within

reach of the compressor to facilitate connection

and maintenance.

The compressor must be earthed and protected against short

cir- cuits in each phase, impermissible voltage uctuation and

phase failure.

The power cable has to be fed into the compressor.

Remove the left side panel, pass the cable under the compressor into the orice (1) and ca-

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.
