Connection To The Compressed Airline; Connection To Power Supply - Comprag DV Serie Bedienungsanleitung

3.5 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 com-
pressed-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.
3.6 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.
