MAINTENANCE

NOTE Technicians must observe important safety precautions while performing these checks.

The FERRUPS UPS is designed to provide years of trouble-free operation. Its internal control system checks the batteries and inverter periodically to ensure reliable operation. In fact, you’ll probably find that your FERRUPS system requires less maintenance than any of your other computer peripherals.

Nevertheless, the FERRUPS UPS and optional external battery cabinets do require some attention to assure continued reliable service. Powerware recommends that you schedule preventive maintenance checks at least every six months. At these checks, the service technician should follow Powerware’s recommended maintenance schedule, which includes the following items:

:Check operating environment for clean, cool, dry conditions.

:Inspect and clean the unit.

:View and record the alarm and inverter logs.

:Check the batteries.

:Check the AC and DC meter functions and recalibrate if necessary.

:Perform an outage test.

:Check and record the values of the first 19 parameters while the UPS is online and on battery.

For more information on preventive maintenance checks, contact your service representative.
