8.4. Serial communication connection
The device can be equipped with optional communication
module. The physical location of the module is the lower option
card slot at the back of the relay. The modules can be installed
in the field (when power is first turned off).
There are three “logical communication ports” available in the
relay: REMOTE, LOCAL and EXTENSION. Depending on the
module type one or more of these ports are physically available
at the external connectors.
