Electrical Installation
WARNING
Always apply control voltage before (or with) mains voltage.
CAUTION
Always follow the specified tightening torque for all power and ground terminal connections.
All Digistart D2 starters include an internal bypass relay that bypasses the soft starter SCRs during run.
This allows the Digistart D2 to be installed in a non-ventilated enclosure without an external bypass
contactor.
