Foreword
Carefully read the whole of this document before installation and start-up of the PR021/K unit.
The PR021/K unit, connected to the Isomax, Emax and Tmax series protection units, allows signalling of various events
which may occur during normal operation of the connected protection unit.
In these events, the PR021/K unit operates the internal relays fitted with power contacts (par. 2.5).
The PR021/K unit also features (only in combination with the protection relays fitted to the Emax series) the ‘Load control’
function. For further information on the ‘Load control’ function, as well as the settings necessary to use this protection,
consult the user manual for the protection relays PR112, PR113, PR122 and PR123.
