It is recommended that GenII POLY CHIP RS485 Protection Plugs be fitted where multiple Genesis II Digital Controllers exist on a network that runs for some distance.
The GenII POLY CHIP RS485 Protection Plugs are also recommended for Genesis II Digital Controllers that have networks that run near devices that are known to introduce transients to the surrounding environment.

Application Notes
The GenII POLY CHIP RS485 protection plug is designed for additional protection on Genesis II Digital Controllers that are located in electrically hostile environments, where the inherent protection of the RS485 drivers are insufficient.

Whilst a GenII POLY CHIP is tripped, the COMMS will not operate until the source of the fault has been removed.

The GenII POLY CHIP RS485 protection plug is not designed for application where a constant earth potential difference exists between Genesis II Digital Controllers.

The GenII POLY CHIP RS485 protection plug does not replace the existing option of GenII RS485I Isolated Comms Cards or the GenII RPTR Isolated Repeater.

The GenII POLY CHIP RS485 protection plugs cannot protect against a permanent potential difference on the COMMS network.
