Connected to the AC power supply terminals R/L1 and S/L2. To
retain the fault display and fault output or when using the high power
factor converter (FR-HC, MT-HC) or power regeneration common
converter (FR-CV), remove the jumpers from terminals R/L1 and R1/
L11, and S/L2 and S1/L21 and apply external power to these
terminals.
The power capacity necessary when separate power is supplied from
R1/L11 and S1/L21 differs according to the inverter capacity.
