• when put into service for the first time
• after prolonged inactivity of the circuit-breaker
HAZARD! RISK OF ELECTRIC SHOCK! Test the circuit-breaker with all
switchgear apparatus de-energized.
IMPORTANT: The checks involve carrying out procedures that can be performed
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).
checks must be carried out on the circuit-beaker and the environment in which it is installed:
Points to be
Checks
checked
1. Sufficient change of air to avoid overtemperatures
2. Clean location, free of all installation refuse (e.g.: cables, tools,
metal splinters)
Switchgear
3. Circuit-breaker mounted correctly (tightening torques, air distances
respected)
4. The installation environmental conditions must be consistent with
the "Environmental conditions" specifications on page 22
1. Power connections tightened to the terminals of the circuit-breaker
2. Cables with adequate cross-section
Connections
3. Correct earth connections
4. Maximum distances of separators respected
Perform some opening and closing operations (See chapter
"Description of the product - circuit-breaker opening/closing
operations on page 15). The spring loading lever must move with
regularly
Operations
WARNING! in the presence of an under-voltage coil the
circuit-breaker can be closed only after the release is
energized
Connect the protection device Ekip TT to the release and verify that
Alarms release
there are no alarms present
State of the With the Ekip Dip release, the status of the circuit-breaker must not
circuit-breaker be in error (see the table on page 50). Perform a closing operation/
with Ekip DIP opening on the circuit-breaker and verify the absence of alarms (see
release the table on page 50).
State of the With the Ekip Touch release, the state circuit-breaker must be read
circuit-breaker correctly (see the table on page 50). Perform a closing operation/
with Ekip Touch opening on the circuit-breaker and verify correct reading of the
release change of state.
With circuit-breaker closed and in conditions of rest (without
Trip Test circulating currents), carry out a Trip test, and verify the opening of
the circuit-breaker
