*4. The input area can be set via
parameters. The setting
within the frame is pre-set at
the factory.
(Pr. 73, Pr. 267).
*5. It is recommended to use
2W1kΩ when the
frequency setting signal is
changed frequently.
CAUTION
To prevent a malfunction due to noise, keep the signal cables more than 10cm away from the power cables.
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 a control box etc., take care not to allow chips and other foreign matter to enter the inverter.

Remove the jumper for the
01160 or less if a DC reactor
is connected. The DC reactor
supplied with the 01800 or
more should be connected to
Earth
these terminals.
