INFO! 

Mechanical start unloader with bypass solenoid is not required.

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

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 = 70% and part winding 2 = 30%. This winding devision redu

-

ces the start-up current during a part winding start to approx. 65% of the value for a direct start.

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

cause motor damage. After the motor has started up with part win-

ding 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!   Ensure  that  power  is  supplied  via  K1  to  winding  1  (70%)  (1U1  /  

1V1 / 1W1) and via K2 to winding 2 (30%) (2U1 / 2V1 / 2W1). The 
motor contactors (K1/K2) are each to be rated for approx. 70% of 
the max. operating current.
