Connection
For the Modbus Module to accept serial commands, a link must be fitted across terminals A1-N2 on
MCD 200 Series starters.
In order for the MCD 500 to accept commands from the serial network, the soft starter must be in
Auto On mode and links must be fitted to terminals 17 and 25 to 18.
In Hand On mode, the starter will not accept commands from the serial network but the starter's
status can still be monitored.
