Battery Replacement Procedure
This procedure covers replacing the MB-10’s internal battery with a new replacement
battery.

switch on the PDU3.
3. At the PDU3, unplug the AC cable between the MB-10 and the PDU3.
4. Remove the cover from the MB-10 T-bracket and unplug all the cables from the
MB-10.
5. Remove the MB-10 amplifier from the T-bracket by loosening the four screws at
the corners of the MB-10. Carefully lift the MB-10 away from the bracket and set it
down on its heatsink fins, with the electronics facing upwards.

a If an external battery is used for encoder backup, the MB-10 will function normally
even if the internal battery is exhausted. The only effect will be a loss of the time/date
stamp used for the internal error-logging function.
