Battery Packs
FN rackmount battery modules utilize flame retardant batteries. They consist of (20) 12V, 7AH
To maintain the optimum battery life, the UPS should be installed in an environment with an ambient temperature of 68ºF to 77ºF (20ºC to 25ºC). Due to the battery manufacturer specification, the FN Series UPS batteries may be operated at 32ºF to 104ºF (0ºC - 40ºC) , but battery life will be substantially reduced if con- tinuously operated at the higher temperature levels. Optional extended battery modules and external battery charger modules are available through Falcon to extend the amount of battery runtime.
Internal Battery Charger
The internal battery charger located inside the UPS module utilizes energy from the utility power source to continuously charge the UPS batteries. The charger operates in "constant power" mode. The UPS batteries are being charged whenever the UPS is plugged in, turned on and operating from utility power. The internal UPS battery charger output is rated at 1.9 amps.
Static Bypass Function
NOTE: Bypass power will only be available If the bypass input is connected at the time of UPS installation.
A manual static bypass pushbutton is located on the FN front control panel. When the UPS is operating from utility in the normal utility mode
Automatic Bypass Transfers
The FN Series UPS module will automatically switch to bypass mode under the following conditions: To energize the connected load when the UPS is first turned on; encounters an overload; encounters an over temperature condition; or upon a UPS failure condition. Should any of these events occur, the UPS will automatically transfer to bypass mode, sound an audible alarm and provide a "bypass" indication on the UPS module LCD display.
Output Filter
As with the input filter stage, the output filter maintains conducted (EMC) and RFI levels below FCC Class A limits.
