    89 • Starting Procedure STARTING PROCEDURE Note: It is necessary to connect a motor to load terminals; otherwise S.SCR or WRONG CONNECTION faults are activated. Other loads such as incandescent light bulbs, resistors, etc. may also cause a WRONG CONNECTION fault. When mains voltage is connected to the RVS-DN, even if control voltage is disconnected, full voltage may appear on the RVS-DN load terminals.
