Issue:
Can multiple motors be connected to 1 soft starter?

Product Line:
ATS48 ATS22

Environment:
All

Cause:
Application requirement

Resolution:
Yes.
Size the soft starter for the total full load amps of all motors to be connected.
Provide separate overload protection for each motor.

For ATS48: Make sure the CLP parameter in the drC menu is set to OFF.
For ATS22: Make sure SSC parameter in the Adj menu is set to OFF.

Motor connections to the soft starter output should not be made or broken while the soft starter is running.  The resulting sudden change in current will cause problems and possible damage to the soft starter or other equipment.
