  • 1 If the starter coil in the magnetic contactor (MC) of the monitored motor exceeds the Shock Relay output contact’s capacity, an auxiliary relay must be installed to prevent damage to the Shock Relay. The instruction manual included with each Shock Relay details how to add this auxiliary relay if required.
