Priorto this procedure, supply power to the critical load through the bypassline (at the SCC). When you close
theUPS module input breaker, power is provided to theU PSre ctifier.The module DC bus voltage ramps up to
thenominal battery voltage and the UPS inverter turns on when theDC bus reaches the proper voltage. You can
thenclose the battery circuit breaker (MBD) andthe UPS module output circuit breaker to place the UPS module
on-line.
Refer to 3.3.1 - Start-UpP rocedurefor more details.
START-UPPROCEDURES
1. Verifythat the control power is applied to the system controlcabinet(check the display
onthe system control cabinet).
2. Waitapproximately two (2) minutes beforeattemptingany other action .
3. Select"SYSTEM CONFIGURATION"screen to verify that the correct model is
displayed.
4. Select"WALK -IN"screen and do the follow ing:
a) Closemoduleinput circuit breaker. Verify that the DC voltage bar on
thedisplay begins to gradually move to the right and the AC input
currentbars do not move to the right more than 10% (40% for modules
withinput filters) after the transform er inrush has subsided.

b) Verifythat the output voltage bar moves to the right after the DC
busbar has reached the 90% point. Both bars should settle near
theirrespective 100% levels.
c) Ifanything happens on the display not mentioned in (a) or (b),
immediatelyopen the m odule input circuit breaker and investigate.
5. Ifstep 4 is successful, s elect "MONITOR/MIMIC"screen and verify module
DCbus and output voltages are at proper nominal level. If so, close
modulebattery circuit breaker.
6. Ifno alarms are present on the "MONITOR/MIMIC"screen, the modul e may be
placedonline by closing the m odule output breaker.
