2.5 Electric diagram
• The electrical installation must correspond to the applicable codes.
•
The mains supply and earthing lines must be of suitable size. See section Electric
cable size and fuses.
• 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.
The complete electrical diagram is available in the electric cubicle of the compressor. For
connection of the supply wires, please see section Electrical connections.

Temperature protection
The compressor is equipped with an ambient temperature sensor. The sensor creates a warning
message on the controller if the ambient temperature rises above 40 °C (104 °F). If the ambient
temperature reaches 45 °C (113 °F), the compressor is stopped.
