II. Carry out the individual steps in the correct sequence:
1. Check all T-1 transformer connections and tighten if necessary. Ensure voltage is tapped for
(480, 240, 208VAC 60Hz or
415,380, 200 VAC 50Hz)
2. Ensure MAIN DISCONNECT SWITCH on the GPU is in the OFF position
3. Connect AC input power cable to the main power outlet and apply electrical power
4. Set current limiting switch on front panel to highest setting (
2000 AMP )
5. Turn GPU main disconnect switch to ON
6. Ensure green main input power lamp is ON , DC voltmeter is indicating 28.5 volts, and no other fault lamps are on
NOTE: Ensure DC output power is not on and DC lamps are off.
7. For all models, connect a load bank to the DC OUTPUT CABLE 1 , set load bank to 2000 Amps , and ensure load bank
switch is OFF
8. Connect a digital multi meter to the test points on the load bank
NOTE: The following test is for Single Output Cable units.
9. Push the WHITE DC ON switch. Observe GREEN DC ON lamp is ON
10. Ensure load bank is ON and cooling fans should begin spinning
11. Switch the load bank to 300 AMP ; verify the voltage at the load bank is 28.0 (MIN) - 28.9 (MAX) Volts DC. Adjust R-67 on
Interface Board to obtain correct voltage output
12. Move load bank switch to AUTO; verify the voltage range at the load bank is 16.0 thru 28.9 volts DC and a minimum
1600 AMPS at full load
13. Observe Amber Warning lamp flashes if DC output volts drops below 21VDC. LET LOAD BANK COOL , push Black
DC Off switch
NOTE: The following test is for Dual Output Cable units.
14. Follow steps 1 thru 8
15. Push
GREEN DC ENABLE ON switch; verify GREEN DC ENABLE lamp is ON
16. Push the WHITE DC 1 ON switch, observe GREEN DC 1 lamp is ON
17. Follow steps 10 thru 13
18. Connect a load bank to the
DC OUTPUT CABLE 2
19. Push the WHITE DC 2 ON switch, observe GREEN DC 2 lamp is ON
20. Repeat steps 13 and 17 using DC OUTPUT CABLE 2. Let load bank COOL , push Black DC 2 Off switch
21. Connect load banks to DC OUTPUT CABLES 1 and 2. (Set Load for 300 Amps Each)
22. Push the WHITE DC 1 & 2 ON switches , observe GREEN DC 1 & 2 lamps are ON
23. Observe voltage on digital multi meter, it should indicate 28(MIN) VDC with loads. Reduce loads to 0 Amps
24. Let load banks COOL , push Black DC 1 & 2 Off switches
25. Disconnect load banks
26. Turn disconnect on main power outlet to OFF
27. Final inspect the unit for missing, loose, components
28. When the unit passes all test, release unit for normal operation
NOTE: The following test is for External Voltage Adjustable units
29. Follow steps 1 thru 2
30. Open control panel door, locate the Interface Board, insure voltage adjust switch (SW1) is in the external (EXT) position
31. Insure over-volt trip switch
(SW2) is in the low (LOW) position. Close control panel door
32. Connect AC input power cable to the main power outlet and apply electrical power
33. Set current limiting switch on front panel to highest setting (2000 AMP)
34. Turn GPU main disconnect switch to
ON
35. Ensure green main power lamp is ON , DC voltmeter is indicating 28.5 volts and no other fault lamps are on
36. Connect a load bank switch to the DC OUTPUT CABLE 1, set load bank to 2000 Amps and ensure load bank switch is
OFF
37. Connect a digital multi meter to the test points on the load bank
38. Push GREEN DC ENABLE ON switch; verify GREEN DC ENABLE lamp is
ON
39. Adjust voltage control knob on control panel to 28 VDC mark
40. Push WHITE DC 1 ON switch, observe GREEN DC 1 lamp is
ON
41. Ensure load bank is ON and cooling fans should be spinning
42. Switch the load bank to 300 AMP; verify the voltage at the load bank is 28.0 (min)
– 28.9 (max) Volts DC. Adjust the
External Voltage control knob on the control panel to obtain correct voltage output
43. Move load bank switch to AUTO ; verify the voltage range at the load bank is 16.0 thru 28.9 volts DC and a minimum 1600
Amps at full load
