Replace Your SLC 5/03, SLC
5/04, or SLC 5/05 Battery Your SLC 5/03, SLC 5/04, or SLC 5/05 processor provides back-up
power for RAM through a replaceable lithium battery. This battery
provides back-up for approximately 2 years. A BATT status indicator
on the front of the processor alerts you when the battery voltage has
fallen below a threshold level.
To replace the lithium battery, follow these steps.
1. Remove power from the SLC 500 power supply.
2. Remove the processor from the chassis by pressing the retainer
clips at both the top and bottom of the module and slide it out.
3. Unplug the battery connector. The figure below shows the
battery connector location.
ATTENTION
Do not remove the processor from the SLC 500 chassis until all
power is removed from the SLC 500 power supply.
ATTENTION
Do not expose the processor to surfaces or other areas
that may typically hold an electrostatic charge.
Electrostatic charges can alter or destroy memory.
