Operation 95
Figure 60 Modu le Start-Up Procedures Screen
Select the Walk -In screen on the LCD disp lay.
Step 3. To energize the UPS module, manually close the input circuit breaker (CB1, Figure 8). This will provide
power to the rectifier. Use the Walk-In screen to monitor the Module DC Bus voltage.
The Input Amps bars should settle at about 10% 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.
Step 4. When the Module DC Bus voltage is at 100%, you can manually close the module battery disconnect
(MBD) circuit breaker (external to the UPS).
WARNING
IF ANY ABNORMAL SITUATION OCCURS DURING THIS WALK-IN
PROCEDURE, OPEN THE INPUT CIRCUIT BREAKER AND
INVESTIGATE THE PROBLEM. EACH INPUT AMPS BAR SHOULD BE
WITHIN 10% OF THE AVERAGE BAR LENGTH. CALL LIEBERT
GLOBAL SERVICES IF YOU NEED HELP.
START-UP PROCEDURES
1. Verifythatthe control poweris appli ed tothe system control cabinet(check thedisplay
onthe system control cabinet).
2. Wait approximatelytwo(2)minutes beforeattempting anyotheraction.
3. Select "SYSTEMCONFIGURATION"screen toverifythat thecorrectmodel is
displayed.
4. Select "WALK-IN" screenand dothe following:
a) Close module input circuit breaker.Verifythat theDCvoltagebaron

currentbars donot moveto theright more than10%(40%for modules
withinputfilters)after thetransformer inrushhas subsided.
