Tab. 2: Legend for OS.95 schematic wiring diagram with CM-SW-01
and star-delta start
The schematic wiring diagram shows a star-delta mo-
tor. OS.95 compressors can also be operated with
other motors. In this case, the time relay control suit-
able for the motor type must be set using the BEST
SOFTWARE, see chapter Selecting the motor start
function, page 16.
