“NORMAL” position.
NOTE THAT S6 SHOULD ALWAYS BE IN “NORMAL” POSITION FOR ONLINE OPERATION
2) Turn S2 switch (static bypass) into “1” (ON) position.
3) Turn on S4 (output switch), now the load is connected to bypass supply.
4) Turn on the S1 switch (rectifier input), into ”1” position. By turning on S1, all lights on the front panel will
