General

The electrical installation must correspond to the local codes. The mains supply and earthing lines must be of suitable size. See section 7.1.

The installation must be earthed and protected by fuses in each phase. An isolating switch must be installed near the compressor. Make sure that this switch is open to isolate the compressor from the mains before carrying out any connection.
