800 Maintenance and Service
801 Regular Maintenance
Best Power designed your FERRUPS to provide years of trouble-free operation. Its microprocessor will
check the batteries and inverter at programmable intervals to ensure proper operation. In fact, you’ll
probably find that your FERRUPS requires less maintenance than any of your other computer peripherals.
Nevertheless, your FERRUPS does require some attention in order to provide you with excellent service.
Best Power recommends that you schedule a Preventative Maintenance check at least every six months. At
this check, the service technician should follow Best Power’s Recommended Maintenance Schedule, which
includes the following:
• Inspect and clean the unit.
• Inspect and record the alarm and inverter logs.
• Check the batteries.
• Check the AC and DC meter functions and recalibrate if necessary.
• Perform a system test.
• Check and record the values of the parameters in menu 3 on line and on inverter.
The technician must observe important safety precautions while performing these checks. For more
information on what your technician should do in a Preventative Maintenance check, or to schedule Preventative
Maintenance with a Best Power-authorized field service representative,
call Best Power’s Worldwide Service .
We’ll be happy to help you.
