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 che-
cked
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#s#7
Connections
1. Power connections tightened to the terminals of the circuit-breaker
2. Cables and busbars with adequate cross-section
2. 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#s#151
#s#159). 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
With Ekip Dip, the circuit-breaker state must not be in error (see table on
page#s#32). Perform a circuit-breaker closing/opening operation and make
sure that there are no alarms (see table on page#s#32)
State of the circuit-
breaker with Ekip
Touch
With Ekip Touch, the circuit-breaker state must be read correctly (see table
on page#s#286). 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, PIN, date
and language
NOTE:
for security reasons, ABB strongly advises you to change the PIN right from the first
access and to keep it with care.
