Check accessories The inspections to perform on the external and internal accessories, if present, before putting into service
are indicated below:
Accessories Checks
1. If Ekip Cartridge is present: check the connections of all modules to Ekip Supply
and the connection between Ekip Cartridge and the lateral terminal box of the CB
For Ekip Signalling 10K and Ekip Multimeter, in the absence of Ekip Cartridge:
check the connection of the bus of the module (W3-W4) to the lateral terminal box
of the CB
External 2. Power up Ekip Touch (and the external modules if there is a separate supply)
modules and make sure they are on
3. Check that the Local bus is enabled (Settings-Modules-Local Bus)
4. Check that the Power Led of each module is on like the Power Led of Ekip Touch
(steady or synchronous flash)
5. Check in the About-Modules menu to make sure that all installed modules are
present and that there are no alarms
1. make sure that module is connected to the internal terminal box
2. Make sure that the auxiliary supply is connected to the internal terminal box
Internal
modules 3. Power up the Trip unit and make sure it is on
4. Check in the About-Modules menu to make sure that all installed modules are
present and that there are no alarms
1. Check that the sensor is connected to the lateral terminal box of the CB in the
proper way and that the terminals are in the right direction (1)
External 2. Power up the Trip unit and make sure it is on
neutral 3. Check in the Settings-Circuit-breaker menu that Configuration= 3P + N;
otherwise change the parameter
4. Make sure there are no alarms
1. Check selectivity connections (between Ekip Touch and the other units) as
shown in circuit diagrams 1SDM000002A1001
2. Provide Ekip Touch with auxiliary power and make sure that CB status is: Open
3. Check that the protection of the selectivity concerned has been enabled
(example: S protection)
4. Select the Zone Selectivity menu and the submenu of the protection concerned;
follow the instructions in points 5, 6, 7 and 8 for each protection activated
NOTE: for selectivity D, consider submenu S for the Forward connections and
G for the Backward connections
Zone selectivity Check Output:
5. Select the Force Output command and check, on the Trip unit connected to the
Ekip Touch output, that the status of its Input = ON
6. Select the Release Output command and check, on the Trip unit connected to
the Ekip Touch output, that the status of its Input = OFF
Check Input:
7. Select the Force Output command on the Trip unit connected to the Ekip Touch
input and check on Ekip Touch that the status of its Input = ON
8. Select the Release Output command on the Trip unit connected to the Ekip
Touch input and check on Ekip Touch that the status of its Input = OFF
1. Make sure that the MOE-E stored energy operating mechanism is correctly
cabled as shown in circuit diagrams 1SDM000002A1001
2. Set the circuit-breaker to the closed position
MOE-E 3. Provide Ekip Touch with auxiliary power and supply the MOE-E device with rated
stored energy voltage
operating
mechanism 4. Perform an opening test from the Test-Test CB menu with the Open CB)
command and check that the CB has opened
5. Repeat the test from the Test-Test CB menu with the Close CB) command and
check that the CB has closed
AUP circuit 1. Check that Trip unit reads status of withdrawable circuit breaker properly by
breaker status means of About-Circuit breaker-CB Status
inputs, if CB is
withdrawable 2. Switch status of AUP device and make sure that Trip unit reads the status
version change properly by means of About-Circuit breaker-CB status menu
