Operation
STEP 4 (Start-Up Procedure)
a.Press the Select pad to put the Master Menu on the LCD. Move the highlighted cursor to
b.Select the Monitor/Mimic Display on the LCD. In the ALARM MESSAGES block (Figure 7), the only alarms present should be Battery CB Open and Load On Bypass. If any other alarm messages are present, do not proceed with the UPS
c.Select the
d.To energize the UPS module, manually close the input circuit breaker (CB1, Figure 3). This will provide power to the rectifier. Use the

START-UP PROCEDURES
1.Wait approximately two (2) minutes before attempting any other action .
2.Select "SYSTEM CONFIGURATION" screen to verify that the correct model number is displayed.
3.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.
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.

START-UP PROCEDURES (Cont'd)
c) If anything happens on the display not mentioned in (a) or (b), immediately open the module input circuit breaker and investigate.
4. If step 3 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.
5. If bypass or static switch circuit breakers (contactor on
are open, refer to
6. System is now ready to assume load. Select "LOAD TRANSFER PROCEDURES" screen for this procedure.
! WARNING
If any abnormal situation occurs during this
The Input Amps bars should settle at 25% or less after the momentary inrush current has subsided. Verify that the DC Voltage bar begins to gradually move to the right.
Verify that the Output Voltage bar moves to the right after the DC Voltage bar has reached the 90% level. Both bars should settle near the 100% line.
Select the Monitor/Mimic display from the Master Menu and confirm that the module DC bus and AC output are at their proper operating voltages.
