Thisprocedurevariesdependingontheinvertertype(singleorthreephase).Makesureyou
followtheprocedureapplicabletoyourequipment.
IftheSafetySwitchhasapre-assembledRGM(seeFigure21),fliptheRGMplate

To connect the AC grid to the Safety Switch – single phase
3-7.6kW inverters:
1. Removethespring-clampterminalinstructionsfrominsidetheswitch.
2. Strip05⁄16''(8mm)oftheACwireinsulation.
3. InserttheACconduitintotheAC-sideknockoutthatwasopened.
NOTE
Connect the equipment grounding before connecting the AC wires to the AC terminal
block.

4. Connectthewirestotheappropriateterminalblocksaccordingtothelabelsonthe
terminalblocks(N,Gnd,L1andL2).
5. Useastandardflat-bladescrewdrivertoconnectthewirestothespring-clampterminals:
