START-UP PROCEDURES
1.Verify that the control power is applied to the system control cabinet (check the display on the system control cabinet).
2.Wait approximately two (2) minutes before attempting any other action .
3.Select "SYSTEM CONFIGURATION" screen to verify that the correct model is displayed.
4.Select
a)Close module input circuit breaker. Verify that the DC voltage bar on the display begins to gradually move to the right and the AC input current bars do not move to the right more than 10% (40% for modules with input filters) after the transformer inrush has subsided.

START-UP PROCEDURES (Cont'd)
b)Verify that the output voltage bar moves to the right after the DC bus bar has reached the 90% point. Both bars should settle near their respective 100% levels.
c)If anything happens on the display not mentioned in (a) or (b), immediately open the module input circuit breaker and investigate.
5.If step 4 is successful, select "MONITOR/MIMIC" screen and verify module DC bus and output voltages are at proper nominal level. If so, close module battery circuit breaker.
6.If no alarms are present on the "MONITOR/MIMIC" screen, the module may be placed online by closing the module output breaker.
Prior to this procedure, supply power to the critical load through the bypass line (at the SCC). When you close the UPS module input breaker, power is provided to the UPS rectifier. The module DC bus voltage ramps up to the nominal battery voltage and the UPS inverter turns on when the DC bus reaches the proper voltage. You can then close the battery circuit breaker (MBD) and the UPS module output circuit breaker to place the UPS module
