4.3.2.3 Externally Bypassed

Non-bypassed models have dedicated bypass terminals,
which allow the soft starter to continue providing
protection and monitoring functions even when bypassed
via an external contactor. Connect the bypass contactor to
the bypass terminals and control it by a programmable
output configured to Run (see parameters 4-1 to 4-9).
