CHAPTER 7
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.
