401 Regular Maintenance

H
Best Power designed the UNITY/I UPS to provide years of trouble-free operation. You will probably find that the
UNITY/I requires less maintenance than your other computer peripherals. Nevertheless, the UPS 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, a qualified technician should inspect and clean the unit,
check the batteries, check the AC and DC meter functions, and perform a power outage test. Important safety
precautions must be observed while performing these checks. For more information on Preventative Maintenance
checks, or to schedule a Preventative Maintenance with a Best Power-authorized field service representative, call Best
Power's Worldwide Service. We'll be happy to help you.

403 Accessing the Alarm and System Logs

The UNITY/I stores information in two logs: the alarm log and the system log. The alarm log stores the 16 most recent
alarm conditions. The system log stores up to 20 UPS events. You can use the logs to keep track of UPS events, and a
technician can use the logs to help troubleshoot the UPS. This section explains how to access and read the alarm and
system logs using the unit's front panel keys and four-digit display.
Note: When you display the alarm and system logs, the front panel keys have different functions. Table 6 below
explains what the keys do when you are displaying the alarm and system logs. (The keys have similar
functions when you display parameters; see Table 3 in Section 302 and the Programming Template inside the
unit's front door.)
