Power supply for the control
circuit
Connected to the AC power supply terminals R/L1 and S/L2. To retain
the fault display and fault output, remove the jumpers across terminals
R/L1 and R1/L11 and across S/L2 and S1/L21, and apply external
power to these terminals.
When using a separate power supply connected to terminals R1/L11
and S1/L21, the required power capacity is 80 VA.
P/+, N/-
Inverter connection
Connect them to the inverter terminals P/+ and N/-.
