3.5.1 Memory-Backup Battery
The lithium battery on the CPU provides
backup of the CPU’s on-board memory during
power loss. The CPU ships with an insulator to
prevent the battery from discharging. To
preserve the battery, the insulating tube should
be left in place as long as possible before
applying AC power.
If the insulator is not removed before applying
AC power, the control panel will show a trouble
situation.
This battery’s shelf-life should exceed 10 years, but if for some reason it fails, the control panel will
show a trouble when powered up. To replace the lithium battery:
1. Make a full backup of all system settings to prevent loss of all programming data.
2. Disconnect all power sources.
3. CPU-3030D only: Disconnect wiring and remove CPU-3030D from backbox (3 screws at top, lift
board tabs out of slot) and remove keypad (4 screws on back, LCD display stays attached).
4. Remove battery from under clip (use fingers, because screwdriver could damage components) and
insert new battery.
5. CPU-3030D only: Replace keyboard, reinstall CPU-3030D into chassis, and reconnect wiring.
6. Follow system power-up procedures.
7. Dispose of used battery promptly. Keep away from children. Do not disassemble and do not
dispose of in fire.
3.6 Attaching Option Boards
If installing option boards into
a CAB-4 Series backbox,
mount & connect those boards
at this time. This section
contains general instructions
for mounting an option board;
see the documentation that
shipped with your board for
any product-specific
instructions.
As described in Section 3.4
“Laying Out Equipment in
Cabinet and Chassis”, up to
eight option boards can be
mounted in CHS-M3 to the
right of the CPU; additional
modules can be mounted in
other chassis.
There are no slots in the first
(back) two layers, but option
boards with tabs (such as NCM-W) will still fit in those positions.
Lift clip gently while
removing battery
