• when the circuit-breaker is 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 Skilled Persons in the electrical field (IEV 195-04-01: person with relevant education
and experience to enable him or her to perceive risks and to avoid hazards which
electricity can create).
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, clearances respected)
4. The installation environmental conditions must be consistent with the
"Environmental conditions" specifications on page 23
1. Power connections tightened to the terminals of the circuit-breaker
2. Busbars with adequate cross-section
Connections
3. Correct ground 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 16). The spring
loading lever must move with regularly
Operations
Connect the protection device Ekip TT to the trip unit and verify that there are no

alarms present
State of the circuit- With Ekip Dip, the circuit-breaker state must not be in error (see table on page 45).

no alarms (see table on page 45)
State of the circuit- With Ekip Touch, the circuit-breaker state must be read correctly (see table on
breaker with Ekip page 45). Perform a circuit-breaker closing/opening operation and make sure that
Touch change of state is read correctly
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
Check and modify the protection dip switches, presence of external neutral and
Ekip Dip parameters
frequency to suit your installation requirements
Connect the Ekip TT device. Check and make the necessary changes to:
Ekip Touch
protection parameters, circuit-breaker configuration, frequency, password, date
parameters
and language
NOTE: for safety reasons, ABB strongly advises you to change the password right from the
first access and to keep it with care.
WARNING! in the presence of an undervoltage coil the circuit-breaker
can be closed only after the trip unit is energized
