PHASE CONTROL RELAY
Read all the instructions carefully
ThephasesequencerelayPSR is an electronic command device in a standardised
2-module DINcontainer,tocontrolvoltage-asymmetryandphase-sequenceinthree-
phasesystems.
During the installation and operation of the instrument, proceed in accordance with the
instructions below:
1) The instrument should be installed by a competent operator following the
installation diagrams carefully
2) The instrument should be installed in a panel from which no access can be gained to
the terminals after installation
3) Do not power or connect the instrument if any part of it is damaged
4) The electrical system of the building in which the instrument is to be installed
should have a switch and a protective device against over-currents
5) The instrument is designed for installations with over-voltage category III and
pollution level 2, in accordance with the EN 61010-1 standard
