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).
Never connect the power cable to
the terminals in the lower stand.
Doing so will damage the inverter.
CAUTION
· Do not turn off the control power (terminals R1/L11 and S1/L21) with the main circuit power (R/L1, S/L2, T/L3) on. Doing so may
damage the inverter.
· Be sure to use the inverter with the jumpers across terminals R/L1-R1/L11 and S/L2-S1/L21 removed when supplying power from
other sources. 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.
· When the power supply used with the control circuit is different from the one used with the main circuit, make up a circuit which will
switch off the main circuit power supply terminals R/L1, S/L2, T/L3 when the control circuit power supply terminals R1/L11, S1/L21
are switched off.
· If the main circuit power is switched off (for 0.1s or more) then on again, the inverter resets and an alarm output will not be held.
