24v DC – 485:  Using 4 – Conductor Wire #

  • If the pre-wire does not have a third insulated data conductor for the 485 ground, terminate the wire as shown below.

  • Use the same termination on both ends.

WIRING – 24v DC – RTS #

  • For guaranteed motor performance the supplied voltage for 24v motors must be 24v DC.

  • See the table below for maximum wire lengths.

  • If the motors are powered using a Power Distribution Enclosure connect the motors to the “+24v DC” and “-24v DC” ports on the terminal blocks.

  • The RS485 ports are unused.
