4.3.3 Inside Delta Installation, Externally Bypassed
Non-bypassed models have dedicated bypass terminals, which allow the MCD 500 to continue providing protection and monitoring functions even when
bypassed via an external bypass contactor. The bypass relay must be connected to the bypass terminals and controlled by a programmable output
configured to Run (see par. 4-1 - 4-9).
