Points to be che-
Checks
cked

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 page20
1. Power connections tightened to the terminals of the circuit-breaker
2. Cables and busbars with adequate cross-section
Connections
3. Correct ground connections
4. Maximum distances of separators respected

Dip that there are no alarms (see table on page38)
State of the circuit-
With Ekip Touch, the circuit-breaker state must be read correctly (see table
breaker with Ekip
on page38). Perform a circuit-breaker closing/opening operation and make

currents), carry out a Trip test, and verify the opening of the circuit-breaker
Ekip Dip
Check and modify the protection dip switches, presence of external neutral
parameters
and 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, PIN, date
