Signal input terminal circuit
For switch input and output signal transmission, generally use shielded cable and wiring short
distance as much as possible, good grounding and shielding layer on the inverter side, try not to use
over 20m transmission distance. Drive in active way, elected to the power of crosstalk necessary
filtering measures are taken, generally recommend that choose dry contact control mode.
Wiring control cable should be kept from the main circuit and high voltage lines (such as the
power cord, motor connecting line, relay or contactor) more than 20cm distance, and to avoid high
voltage lines parallel to and can't be avoided and the high voltage lines cross, the proposal USES
vertical wiring way, in order to prevent the misoperation caused by disturbance frequency converter.

Note: using an external power supply, PLC and 24V jumper cap must be removed, otherwise it
will damage the product.

When the input signal from the NPN transistor, according to the use of power supply, please set
the + 24 V and PLC jumper cap according to the figure.
