1) Remove the upper screws.
2) Remove the lower screws.
3) Pull the jumper toward you to
remove.
4) Connect the separate power supply
cable for the control circuit to the
upper terminals (R1/L11, S1/L21).
CAUTION
· When using separate power supply, always remove the jumper across terminals R/L1 and R1/L11 and across S/L2 and S1/L21.
The inverter may be damaged if you do not remove the jumper.
· The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than the
primary 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.
200V class
400V class
· If the main circuit power is switched OFF (for 0.1s or more) then ON again, the inverter resets and a fault output will not be held.
