Electrical Installation

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