Separate power supply for the control circuit
In an alarm condition the frequency inverter’s integrated alarm relay only remains active as long
as there is a mains power supply on terminals R/L1, S/L2 and T/L3. If you want the alarm signal
to remain active after the frequency inverter has been switched off a separate power supply for
the control circuit is required, which should be connected as shown in the circuit diagram below.
Remove the shortening jumpers from the terminal block and connect the 380–480V AC, 50/
60Hz mains power supply to terminals R1/L11 and S1/L21. The control circuit power consump-
tion on L11/L21 is 60VA for 00380 or less and 80VA for 00470 to 12120.
