Introduction
The protection release is able to identify some faults and to signal them through LEDs or the
display; you need to identify the cause and eliminate it before re-closing the circuit-breaker,
both locally and remotely.
WARNING! identification of the faults must be managed only by Expert Persons
in the electrical area (IEV 195-04-01: Person with sufficient training and
experience to allow him/her to perceive the risks and to avoid the hazards
potentially created by electricity). Indeed, it may be necessary to perform
insulation and dielectric tests on part or all of the installation.
Some failures involve partial operation of the circuit-breaker. Consult the paragraphs “Faults,
causes and remedies” on page 247 and “Faults signalled on the display” on page 250 where
the possible causes of the main faults are listed.
