5.2 Standard motor, design for direct or partial winding start

INFO

A mechanical unloaded start with bypass solenoid valve is

not required.

Electrical connection

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.
