recommendations.
Maximum Control Wire Recommendations
Do not exceed control wiring length of 30 meters (100 feet). Control
signal cable length is highly dependent on electrical environment and
installation practices. To improve noise immunity, the I/O terminal block
Common must be connected to ground terminal/protective earth. If using
the RS485 (DSI) port, I/O Terminal 16 should also be connected to
ground terminal/protective earth.
