NOTES When using separate power supplies, always remove the jumpers across terminals R/L1 and R1/L11
and across S/L2 and S1/L21. The inverter may be damaged if the jumpers are not removed.
The voltage should be the same as that of the main control circuit when the control circuit power
is supplied from other than the input side of the MC.
The power capacity necessary when separate power is supplied from R1/L11 and S1/L21 differs
according to the inverter capacity.

If the main circuit power is switched OFF (for 0.1 s or more) then ON again, the inverter is reset and
a fault output will not be held.
