FA241285
22 July 2022
Issue:
Looking for the fuse size needed for CL1-CL2 on ATS22 soft starts
Product line:
ATS22, Altistart 22
Environment:
All models (S6 and S6U)
Cause:
The drawings and installation show fuse/overcurrent protection on CL1, but no notes on what size or type of protection to use.
Resolution:
The CL1 - CL2 control voltage input should have a 1A fast acting fuse, or 1A circuit breaker for each ATS22 unit. This applies to the 120V and 230V control supplies (Q, S6 and S6U).
