6. MAINTENANCE
6.1 CFR Maintenance
The electronic components used in the UPS require no maintenance. If
the unit fails to perform a specific function, refer to the troubleshooting guide.
The guide lists typical symptoms, causes and solutions that apply to the UPS,
starting with the most obvious and working systematically through the unit.
By establishing a routine maintenance program and following the
guidelines contained in this manual, your Alpha CFR will continue to provide
years of trouble-free service.
6.2 Battery Maintenance
The maintenance free batteries used in the UPS will be affected by many
variables including operating temperatures, number of discharges over the life
of the battery, charging characteristics, and low voltage cell cutoff. The Alpha
CFR complies with all factory recommendations for charging and discharging
batteries to ensure optimum performance and the longest possible battery life.
During normal operation, the UPS batteries will tend to increase in
capacity over the first three to twelve months of service. There can be as
much as a 20% increase in available backup power after the first ten to fifteen
battery discharges. Once the batteries reach this peak, they will slowly begin
to lose capacity until, eventually, they will be unable to provide the required
backup power.
Note: Battery
terminals vary in size
and shape.
