AXC-232++ RS-232/422/485 Interface Card
Replacing the Lithium Batteries
The AXC-232++’s lithium batteries have a life of approximately 5 years to protect its memory.
When DC power is on, the batteries are not used. When you install the AXC-232++, record the date
the batteries should be replaced.
Before you remove the lithium batteries, contact your dealer and verify that they have a current
copy of your program; this avoids any inadvertent loss of data and prevent an unnecessary service
outage.
1. Discharge the static electricity from your body.
2. Unplug the two-pin power connector and any other connectors.
3. Slide the card out of the cardframe.
4. Carefully slide each battery out of its socket (FIG. 6), and insert the new battery.
5. Slide the card back into the cardframe.
6. Replace the front panel and refasten the two screws.
7. Reconnect any connectors that you removed.
There is a danger of explosion if you replace the batteries incorrectly. Replace
batteries with the same or equivalent type recommended by the manufacturer.
Dispose of the used batteries according to the manufacturer’s instructions. Never
recharge, disassemble, or heat batteries above 212°F (100°C). Never solder directly
to the batteries or expose the contents of the batteries to water.
