What is the fuse size needed to protect CL1-CL2 on the ATS22 soft starts?
ATS22, Altistart 22
All models (S6 and S6U)
The drawings and installation show fuse/overcurrent protection on CL1, but no notes on what size or type of protection to use.
According to our L3 team, The CL1 - CL2 control voltage input should have a 1A fact acting fuse, or 1A circuit breaker for each ATS22 unit. This applies to the 120 V and 230 V control supplies (Q, S6 and S6U)
