1.
Make sure that no units are powered before starting the installation procedure.
2.
Connect the inputs and outputs using the extractable terminal boards provided and fasten with the
screws.
Important note:
Respect the polarity for RS-485 connections.
3.
Check that the device is connected to network with central positive power before powering it.
4.
The "DATA" LED (2) will light up steady to indicate that the device is powered.
5.
The "DATA" LED (2) will blink steady to indicate that the device is receiving input data.
6.
Make sure that appropriate terminal resistors (120) are inserted at the RS-485 line ends, where
needed.
