10. TROUBLESHOOTING
This section examines some of most likely problems that can compromise correct operation of the UPS, attempting to solve them
and identifying the possible causes and remedies.
WARNING!
The UPS internally generates hazardous electrical voltages.
All maintenance must be performed solely and exclusively by authorized personnel.
If you have difficulty in getting the UPS to work, the reason may be among those listed below. For any other problem, you are advised
to get in touch with your dealer or service organisation directly.
For quick and effective action, when you call it is important to give precise details of the defect, the model number and the manufac-
turing serial number that can be found on the conformance and inspection certificate or on the data plate on the bottom of the UPS.
NOTE: the UPS has an audible alarm feature to alert you of potential power problems. Use Table 8 to determine and resolve the
UPS alarms and conditions.
10.1. SILENCING AN AUDIBLE ALARM
Before silencing an alarm, check the alarm condition and perform the applicable action to resolve the condition (see Table 8). To
silence the alarm for an existing fault, press the button. If UPS status changes, the alarm beeps, overriding the previous alarm silencing.
