Electrical connection

5.4 Connection of the drive motor

Designation on the name plate

Y/YY

Compressors marked in this way are suitable for direct or part winding start. The motor winding is

divided into two parts: part winding 1 = 50 % and part winding 2 = 50 %. This winding division
reduces the start-up current during a part winding start to approx. 50 % of the value for a direct start.

Mechanical start unloader with bypass solenoid is not required

.

In the factory, the motor is connected for direct starting (YY). For part winding start (Y/YY) remove the
bridges and connect the motor feed cable according to the circuit diagram.

INFO

The compressor is equipped with a motor in Part-Winding design.

ATTENTION Failure to comply results in reversed fields of rotation and can cause

motor damage. After the motor has started up with part winding 1,
part winding 2 must be switched on after max. 1 second delay.
Failure to comply can be detrimental to the service life of the motor.

ATTENTION Terminal boxes and cable screw connections must be properly

closed, in order to achieve the protective class IP 66.

Use Ex cable

screw fittings (pay attention to correct assignment of the cable and
fitting diameter).
Icing/condensate formation in the terminal box of the compressor
must be avoided due to the danger of short circuits (e.g. through
appropriate suction gas overheating). Carefully set suction gas
overheating temperature! Check regularly for icing!
