Some electronic contactor coils are not suitable for direct switching with PCB mount relays. Consult the contactor manufacturer/
supplier to confirm suitability.

5.5.4 Bypass Contactor Output

The bypass contactor output (03, 04) closes when the soft start is complete (when the starting current drops below 120% of the
programmed motor full load current) and remains closed until the beginning of a stop (either soft stop or coast to stop).
This output is only available on models MCD6-0590C~MCD6-1134C.
If a non-bypassed soft starter is installed with an external bypass contactor, the soft starter current rating changes. Enable param-
eter 20-7 External Bypass to increase the maximum current rating and adjust the soft starter thermal model.
