Starting-up the system
11. Switch on the AC mains/utility power.
12. Refer to illustration "AC Wiring" on page 38 and verify the AC input
voltages at the AC wiring terminals:
System Voltage Value
ALL Neutral to Earth Ground ~0V
3 phase L1 to L2, L2 to L3, L3 to L1 ~208V
Neutral to L1 / L2 / L3 ~120V
2-pole L1 to L2 ~208V
Neutral to L1 / L2 ~120V
Split Phase L1 to L2 ~240V
Neutral to L1 / L2 ~120V
13. Check that the battery polarity is correct.
14. Turn on the AMPS24 DC Input breakers for each installed shelf.
15. Switch on the external battery breakers or complete the fuse circuit.
16. Verify that the system starts up and that the controller switches on:
the controller display initializes with three LEDs blinking while a self-
test runs for 15 seconds. (Ignore any alarm conditions indicated by
the bottom two LEDs.)
The graphic display shows the correct DC voltage.
