• 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 appara
tus 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).
carried out on the circuit-beaker and the environment in which it is installed:
Points to be che-
Checks
cked
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 "Environ-
mental conditions" specifications on page 21
1. Power connections tightened to the terminals of the circuit-breaker
2. Cables and busbars with adequate cross-section
Connections
2. Busbars with adequate cross-section
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
Connect the protection device Ekip TT to the release and verify that there are no
Alarms release
alarms present
State of the circuit- With the Ekip Dip release, the status of the circuit-breaker must not be in error
breaker with Ekip (see the table on page 47). Perform a closing/opening operation on the circuit-
DIP release breaker and verify the absence of alarms (see the table on page 47).
State of the circuit- With the Ekip Touch release, the state circuit-breaker must be read correctly (see
breaker with Ekip the table on page 47). Perform a closing/opening operation on the circuit-breaker
Touch release and verify correct reading of the change of state.
With circuit-breaker closed and in conditions of rest (without circulating currents),
Trip Test
carry out a Trip test, and verify the opening of the circuit-breaker
WARNING! in the presence of an under-voltage coil the circuit-
breaker can be closed only after the release is energized
