5 System startup
After completing the enclosure installation and the power system wiring, perform the following startup and test
procedure:
5.1 Connecting the batteries
1. Check and verify the polarity of all the batteries.
2. Open all the DC breakers and temporarily remove all the DC fuses. The breakers must be closed and the fuses
reinstalled after the testing is complete.
3. Unplug all rectifiers except one.
4. Switch on the AC breakers to apply power to the rectifier shelf.
5. The controller will perform a short self-test as it boots up.
6. Alarm conditions will likely be present and will probably not clear because there is no DC load on the rectifiers
since all the loads are disconnected.
7. The system voltage will be visible on the controller display.
8. With the batteries disconnected, measure the voltage difference between the power system and the battery
string. The voltage difference should be less than 3 V. If the voltage difference is greater than 3 V, check the
cable connections and the conditions of the batteries. Correct the problems and then proceed. If you are
unable to correct the problem, switch off the AC input power and contact Alpha Technologies.
9. Measure the battery voltage at the battery connector and ensure that the polarity is correct. Connect the first
string of batteries by plugging in the Anderson connector. Repeat this step for the remaining string of batteries.
10. Plug in the remaining rectifiers one at a time.
11. All the alarms should clear and the audible alarm will switch off provided the batteries are slightly discharged.
12. Switch on the all the remaining breakers. The air conditioner fans should start.
13. Apply the DC loads by switching on the DC powered equipment.
