5.4 Commissioning procedure
1. Remove the covers and check that all connections are made according to the installation
drawing. Verify that all connections are properly tightened with sufficient torque.
2. Ensure that load and battery MCB breakers are set to OFF position - ensuring the load
and battery strings are connected.
3.
Ensure that all rectifier modules are removed. If not, remove each one in turn starting
from the rightmost position.
4.
If the rectifier subrack has dip switches for addressing, verify that the dip switches are
set correctly.
5. Check the battery polarity with the multimeter (3½ Digit, 0·1% dc). Place the positive
lead of the meter to the positive busbar and the negative lead to the battery breaker. The
meter must now show a positive voltage. If the voltage is negative, change over the
connection of the blue and black battery cables to the batteries.
6. Turn on the AC mains voltage.
7. Measure the AC voltage on the AC terminal block between phases and neutral. The
correct value is approximately 230V. If the value is different, check the AC connection.
8.
Plug in all rectifier modules, starting from the leftmost position. Make sure to fasten the
rectifiers again. The rectifiers will turn on automatically.
9. Set all load breakers into the “1” (ON) position.
10. The green LED on the controller should blink for approximately 20 sec.
11.
The output voltage will increase slowly to U1 (float charge voltage).
12. Turn the battery breaker(s) to the “1” (ON) position.
13. Set the battery current limit according to the battery manufacturers requirements.
14. If any alarms are present, they should be reset in accordance with the procedure for the
installed controller.
15. The system should now be without alarms.
16. Attach all the system covers in their correct places.
17. Check that all changes to drawings, if any, have been completed.
18. Clean the site.
19. Fill in the commissioning record (see end of chapter).
