To replace a lithium battery pack, perform the following steps:
1. Unscrew the cover from the enclosure and set it aside.
2. Using a small standard blade screwdriver, remove the two #4-40 × 7/8” screws located to the right and
left side of the display (Figure 6.1).
3. Lift the board assembly from the enclosure, making sure it does not contact the enclosure.
4. Disconnect the eldbus input cable from TB4 of the eldbus interconnect board. If the bus is powered,
take precautions to prevent the eldbus conductor wires from touching and short-circuiting the network.
5. Loosen the Velcro strap, disconnect the battery from the J1 connector on the main board, and remove the
spent battery pack from the enclosure (Figure 6.1).
