3.2 Terminal connection diagram (FR-A760)
Sink logic
*1. DC reactor
Be sure to connect the DC reactor
Main circuit terminal
supplied with the FR-A760-01040 or more.
When using the FR-A760-00840 with LD
Control circuit terminal
or SLD set, always use a DC reactor
(option).
When a DC reactor is connected to the
FR-A760-00840 or less, remove the
jumper across P1-P/+.

*2. To supply power to the
control circuit separately,
remove the jumper across
R1/L11 and S1/L21.

when the frequency setting signal
is changed frequently.
CAUTION
· To prevent a malfunction due to noise, keep the signal cables more than 10cm (3.94inches) away from the power cables. Also separate the main
circuit wire of the input side and the output side.
· After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.
When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.
· Set the voltage/current input switch correctly. Different setting may cause a fault, failure or malfunction.
