This terminal can be used with standard inverters equipped with an RS485 communications card (option).
Route the wiring of the control terminals as far from the wiring of the main circuit as
-
possible. Otherwise electric noise may cause malfunctions.
Fix the control circuit wires inside the inverter to keep them away from the live parts of
-
the main circuit (such as the terminal block of the main circuit).
2.3.8 Switching of SINK/SOURCE (Jumper Switch)
Before changing the jumper switch, wait for at least five minutes after the power has been
turned off, then check that the DC link circuit voltage between main circuit terminals P (+) and
N (-) does not exceed the safety voltage (+25 VDC) using a multimeter. An electric shock may
result if this warning is not heeded as there may be some residual electric charge in the DC
bus capacitor even after the power has been turned off.

(1) Outputs a contact signal (SPDT) when a protective function has been
activated to stop the motor.
Contact rating: 250 VAC 0.3A cos ∞ = 0.3
+48 VDC, 0.5A
(2) A command similar to terminal [Y1] can be selected for the transistor
output signal and use it for signal output.
(3) Switching of the normal/negative logic output is applicable to the fol-
lowing two contact outputs: "Terminals [30A] and [30C] are short-
circuited for ON signal output" or "the terminals [30B] and [30C] are
short-circuited (non-excite) for ON signal output."
(1) Used to connect the inverter with PC or PLC using RS485 port.
(2) Used to connect the inverter with the remote keypad. The inverter
supplies the power to the remote keypad through the extension cable
for remote keypad.

Functions
To switch the sink/source of the digital
input signal, change the position of the
jumper switch using a pair of long-
nose pliers, as shown in Figure 2.17.
At the factory setting, the jumper
switch is positioned at SOURCE for
the EU version except three-phase
200 V model and at SINK for the Asian
and Japanese versions.
