Introduction
The general check is necessary:
• 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).
General checks
Before putting it into service for the first time or after a prolonged period of inactivity, some checks must be
carried out on the circuit-beaker and the environment in which it is installed:
Points to be
checked
Checks
Switchgear
1. Sufficient change of air to avoid overtemperatures
2. Clean location, free of all installation refuse (e.g.: cables, tools, metal splinters)
3. Circuit-breaker mounted correctly (tightening torques, clearances respected)
4. The installation environmental conditions must be consistent with the
“Environmental conditions” specifications on page 21
Connections
1. Power connections tightened to the terminals of the circuit-breaker
2. Cables and busbars with adequate cross-section
3. Correct ground connections
4. Maximum distances of separators respected
Operations
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
WARNING! in the presence of an undervoltage coil the circuit-breaker
can be closed only after the trip unit is energized
Trip unit alarm
Connect the protection device Ekip TT to the trip unit and verify that there are no
alarms present
State of the
circuit-breaker with
Ekip Dip trip unit
With trip unit Ekip Dip, the circuit-breaker state must not be in error (see table on
page 47). Perform a circuit-breaker closing/opening operation and make sure that
there are no alarms (see table on page 47)
State of the
circuit-breaker with
Ekip Touch trip unit
With trip unit Ekip Touch, the circuit-breaker state must be read correctly (see
table on page 47). Perform a circuit-breaker closing/opening operation and make
sure that change of state is read correctly
Trip Test
With circuit-breaker closed and in conditions of rest (without circulating currents),
carry out a Trip test, and verify the opening of the circuit-breaker
Ekip Dip parameters
Check and modify the protection dip switches, presence of external neutral and
frequency to suit your installation requirements
Ekip Touch
parameters
Connect the Ekip TT device. Check and make the necessary changes to:
protection parameters, circuit-breaker configuration, frequency, password, date
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.
