The backup batteries may need to be replaced for a number of reasons, for
example, end-of-life, insufficient capacity, etc.
• The backup batteries, although only 24 VDC, carry enough charge to be
dangerous.
• When connecting batteries, or when working in the vicinity of the battery
terminals, take care not to accidentally cause a short circuit. In particular
metallic tools or metallic watchstraps can also inflict
Ë Î D Î ó Î
burns to the user
as well as cause a short circuit.
The backup batteries contain substances that are potentially hazardous
to your health and to the environment.
1. Disconnect the connections from the positive and negative terminals on the
backup batteries.
2. Loosen and remove the wing nut from the batteries securing bracket (see
Figure 68 on page 153).
3. Remove the bracket securing the backup batteries to the chassis.
4. Remove the backup batteries.
5. Install new backup batteries as described under “Backup batteries” on page
