Compressors with this marking are suitable for direct or partial winding start. The motor winding is
subdivided into two parts:
Part winding 1 = 50 % and part winding 2 = 50 %.
This winding division reduces the start-up current needed for a part winding start to approx. 50 % of
that for a direct start.
The motor is wired for direct start (YY) at the factory. For part winding start Y/YY the bridges must
be removed and the motor feed line connected according to the circuit diagram:
