Introduction
Read this document carefully and completely.
The PR212/D-M communication units, connected to the PR212/P protection unit, make it
possible to connect Isomax circuit-breakers to a centralised control system to allow readout and/
or modification of the protection parameters (a more sophisticated adjustment compared with
manual configuration carried out using dip switches on the PR212/P), readout of circulating
currents, state of the circuit-breaker, transmission of opening and/or closing commands and
others, too.
The PR212/T actuation unit, connected to the PR212/D-M communication units, means that
the opening and closing commands coming from the remote supervision system can be actuated
(see par. 3).
In order to open or close the circuit-breaker from the remote supervision system, it is necessary
to have the following:
·
PR212/D-M communication unit,
·
PR212/T actuation unit
·
motor operator
For correct use and management of the PR212/P protection units, which can be interfaced
with the communication units with Modbus

protocol [PR212/D-M], and with the
PR212/T actuation units, what is indicated in the following documents must be taken into
