Siemens SENTRON 3WL10 - Final Tests

5.5.3 Final tests
After completion of the general and accessory tests, perform the activities in the 󹪝nal checklist
table.
No. Activity Description
1 Circuit breaker open Put the circuit breaker into the OPEN position.
2 Circuit breaker connected On the withdrawable breaker, move the circuit breaker into the CONNECT posi‐
tion. Stow the racking handle in the recess provided for it.
3 Parameterization Parameterize ETUs of the 3-series directly with the rotary coding switch and ETUs
of the 6-series with the TD310 test device through the power supply.
If parameterization is not performed, the default values of the parameters are so
high that the highest safety is ensured (minimally sensitive protection setting).
Only the overload release (LT) on an ETU of the 6-series has a medium operating
value that prevents direct tripping when a circuit breaker is closed, if it has not
been modi󹪝ed by the user.
4 Removing the TD310 test device Remove the TD310 test device, if connected.
5 Connecting the voltage Connect the auxiliary voltage.
6 Closing the switchboard Close the control panel door.
7 Charging the springs Charge the springs with the manual lever.
8 Undervoltage release Make sure that voltage is applied to the undervoltage release.
9 Open and close the closing coil and
shunt release
Make sure no voltage is applied to the closing coil and shunt release.
10 Mutual mechanical interlocking of
the circuit breaker
Make sure that the mutual mechanical interlocking of the circuit breaker is not
active, if installed.
11 Interlocks and locking devices Make sure that the interlocking devices of the circuit breaker, if installed, are not
operated or enabled.
12 Status signals Check whether the display on the front of the circuit breaker functions: Circuit
breaker OPEN: The springs are charged and the status indicator shows "CHARGED".
Note
To perform the insulation test on the switchboard, the voltage circuit of the metering function
must be interrupted. This is done by pulling out the metering module MF Basic / Advanced to its
dedicated disconnect position, which is located next to the ETU.
The general rules for the insulation test procedure for switchboards acc. to IEC 60364-6 must be
followed.
