5.9.2 In-line Installation, Externally Bypassed
Models MCD6-0590C~MCD6-1134C have dedicated bypass terminals, which allow the protection and monitoring functions of the
soft starter to work even when the soft starter is externally bypassed.
The bypass busbars are at the top of the unit and are labeled T1B, T2B, T3B.
The bypass contactor must be connected to the bypass terminals and controlled by the soft starter's bypass contactor output (ter-
minals 03, 04).
