POWER CIRCUITS
Inside delta installation, externally bypassed
Non-bypassed models have dedicated bypass terminals, which allow the EMX3 to continue providing protection and monitoring
functions even when bypassed via an external bypass contactor. The bypass contactor must be connected to the bypass terminals
and controlled by the soft starter's run output (terminals 23, 24).
