Replacing the Main Battery Pack

Periodically you must replace the main battery pack. FBxConnect provides a battery life
indicator to show the number of days in use. In addition, if you use a lithium battery for
main power, the Status LED shows yellow when the battery is low and needs to be
replaced.
If lead acid battery voltage falls below 4.7V, the battery can no longer be recharged, and
the charging system considers the battery dead. You must replace the battery.

To replace the HMI module, line up the printed circuit board (PCB) with the slot on
the back and gently press it back on. Tighten the four captive fastening screws.
Replace the end cap. Screw the end cap clockwise (eight full turns) until it is tightly
sealed to the enclosure. Re-attach the retaining clamp, if applicable (see
