| DCIPS1B-S-00-B6 Power Supply System
5.1 Commissioning Overview
Before delivery the system was thoroughly inspected and tested. The following chapter is a
guide to the set-up and operation of the control functions of the system.
NOTE
Before starting commissioning read the product description for the individual
components.
WARNING
ONLY TECHNICAL STAFF WITH THE NECESSARY EXPERIENCE AND
KNOWLEDGE, WITH REGARD TO THE POWER SUPPLY SUPPORT SYSTEM AND ITS
BATTERIES, MAY PERFORM THE COMMISSIONING. IT IS IMPORTANT TO FOLLOW
ALL SAFETY REGULATIONS.
If there are any difficulties in increasing the voltage to alarm level, the alarm level can be
adjusted to a lower level.
5.2 Tools and Test Equipment
5.2.1 Tools List
The essential commissioning tools are listed in the Installation chapter.
5.2.2 Test Equipment
•
Multimeter (3½ Digit, 0–1%DC)
•
Load resistance, to fully load of two rectifiers
5.3 Preparation
Check the installation to ensure the following:
•
Grounding: The equipment is correctly grounded. The grounding cable size, color and
routing conform to the requirements.
•
Power: The incoming mains AC power is available for this site. The site power switch
and circuit breakers are clearly labeled. The power cables are correctly terminated.
•
The site is clean and safe. Check that the system/cabinet is free of any unwanted
objects or insects that may have got in during the installation.

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 120V/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. Verify correct polarity on the battery connection by measuring the voltage drop across
the battery breaker(s) (Normally not more than 5V DC).
11. The green LED on the controller should blink for approximately 20 sec.
12. The output voltage will increase slowly to U1 (float charge voltage).
13. Turn the battery breaker(s) to the "1" (ON) position.
14. If any alarms are present, they should be reset in accordance with the procedure for the
installed controller, ACX or PCC.
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).
