Maximum Control Wire Recommendation
Do not exceed control wiring length of 30 m (100 ft). Control signal cable length is highly dependent on electrical
environment and installation practices. To improve noise immunity, the I/O terminal block Common may be connected to
ground terminal/protective earth. If using the RS485 (DSI) port, I/O Terminal C1 should also be connected to ground
terminal/protective earth. Additionally, communication noise immunity can also be improved by connecting I/O Terminal
C2 to ground terminal/protective earth.
