Falcon RACKMOUNT UPS PLUS FN4KRM-2TX - Manual (Page 40)

8.0 MAINTENANCE
T he FN Series UPS requires very little maintenance. The batteries are located inside the battery module and
consist of (20) Yuasa 12V, 7AH or equivalent, sealed, VRLA, maintenance-free, lead-acid batteries.
Batteries must be kept recharged to prevent excessive self-discharging, which may result in their
premature failure. When connected to the battery module, the UPS will continuously recharge the bat-
teries when plugged in and turned on. When not in use, batteries must be recharged every 6 months
to keep your warranty valid.
1. The UPS and Battery Care
Keep the area around the UPS clean and dust free. If the area around the UPS becomes very dusty, clean it
with a vacuum cleaner. To assure the full 3-5 year battery life, keep the UPS battery module at an ambient
temperature of 77ºF (25ºC). Other than replacement at three to five years of service, no other battery
maintenance is required.
2. Storing the UPS and Batteries
When storing the UPS for any amount of time, it is recommended to connect the battery module and turn on
the UPS for at least 24 hours, every four to six months to ensure full recharging of the batteries. This will pre-
vent excessive battery self-discharge.
3. When to Replace Batteries
We suggest the battery pack(s) be replaced every 3-5 years for FN units that are operated and maintained in
a 77ºF (25ºC) environment. Higher temperature operating environments will decrease the battery life.
Typically, if the UPS is installed in a 104ºF (40ºC) or above operating environment, the batteries will need to
be replaced once a year.
In order to assure the performance of the FN Series UPS, check the battery every two to three months by
performing a UPS self-test. If at any time the UPS LCD panel displays the weak or defective battery icon or
error code, the batteries need replacing. Contact the Falcon Electric Service Department to order replacement
batteries.
4. Battery Replacement
Battery replacement inside the battery module must be performed by a qualified service technician. Contact
Falcon service when battery replacement is required.
NOTE!
NEVER ATTEMPT TO REPLACE THE BATTERY PACKS WHILE THE UPS IS IN
BATTERY MODE.
