Recommended power cable cross sectional area and fuse sizes
-
The power cable cross sectional area should be matched to the current drawn by the
compressor.
-
The compressors can only be operated onthree-phase earthed system (TN).
-
The compressor must be supplied from the distribution board equipped with a slow blow
fuse and circuit-breaker that enables the compressor power supply to be completely
disconnected.
-
Electrical connection of the compressor should be performed in accordance with the
attached electrical diagram.
-
Only authorised personnel or qualified electrician is allowed to perform electrical
connections.
-
Use the required safety measures in accordance with the suitable regulations.
-
Calculate the power cable cross sectional area and fuse sizes according to the local
regulations and operating conditions.
-
Below there are presented the recommended power cable cross sectional areas and fuse
sizes for standard compressors.
-
A user takes a full responsibility for selection of an electrical system and power supply
connection for the compressor.
4.3. Compressed air connection
It is recommended to use galvanized steel or plastic tubes for the compressed air system.
When the compressed air treatment equipment (filters, dryer) is installed, the existing
compressed air piping should be replaced with a new one, unless air supplied previously
was treated by similar equipment.
Each BERG compressor should be connected to the compressed air network by using a
flexible conduit or flexible connector (axial expansion joint) and shut-off valve.
