5.2 Installation – electrical
It is the responsibility of the operator/ owner to ensure that the compressor is wired professionally. Any
electrical work should be carried out by a competent electrician and installed to meet all applicable local
and national codes and regulations.
Therefore please read the following regulations carefully:
Current, voltage and polarity of the power system must match the information on the appliance rating
plate of the motor.
The fuse regarding to the control lead should have (61) 2A.

The cross-sectional area of the lead-in must be chosen in such a way that, when the compressor is
operating, the voltage on the terminal board or power relay does not fall below the necessary
operating voltage. (12, 24, 48 or 80 V)

The control 61 and KK can have at maximum a 0,75mm² Cu wire.
The oil level on the compressor block must be checked. The oil level must be within/ at the red circle
of the oil level eye.
Regulation:
The compressor is regulated automatically by means of a pressure switch depending on the compressed
air requirements. After the system has been switched on for the first time, the pressure switch controls the
compressor’s operating corresponding to the set pressure.
