power supply
*2.To supply power to the control circuit
separately, remove the jumper
across R1/L11 and S1/L21.
Control input signals (No voltage input allowed)
Terminal functions

used as PTC input
terminal.
Terminal 4 input selection

*4.Terminal input specifications
can be changed by analog
input specifications switchover
(Pr. 73, Pr. 267) (initial settings
in frame). Set the voltage/cur-
rent input switch in the OFF
position to select voltage input
(0 to 5V/0 to 10V) and ON to
select current input (0 to
20mA). Terminal 2 and 10 can
be used as PTC input terminal.
(Pr. 561).
*5.It is recommended to use 2W,
Ω
1k when the frequency set-
ting signal is changed fre-
quently.
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.
Set the voltage/current input switch in the correct position. An incorrect setting may cause a fault, failure or malfunction.

Remove the jumper across P1
and P/+ for the 01160 or less if a
DC reactor is connected. Be sure
to connect the DC reactor sup-
plied with the 01800 or more.
