3.5.2.2 Wiring specifications of encoder
There are 2 kinds of encoder input signals for door inverter——encoder of Push/pull
or OCT type. Please choose the encoder below 1024 pulse and using 24V power
supply.

On the wiring of push/pull or OCT output encoder, the power of encoder should be
jointed at +24V terminal, the encoder ground at +24V GND terminal, PA and PB of
encoder at PA and PB of inverter, and the close terminal of shielded wire at GND
terminal of inverter.
