R1/L11,
S1/L21
Power supply for the control
circuit
Connected to the terminals P/+ and N/-. To retain the fault display and fault
output, or to use the converter unit (FR-CC2), remove the jumpers installed in
terminals R1/L11 and S1/L21, and apply external power supply to these
terminals.
The power capacity necessary when separate power is supplied from R1/L11
and S1/L21 is 80 VA.
