Installing the SLC 5/01, -5/02 and Fixed Controller Battery
For battery installation or replacement do the following:
1. Open the door of the processor. Do not remove processor power.
2. Locate the battery. Refer to page 10 for battery location.
If you are replacing an old battery, unplug the existing battery connector
and remove from the retainer clips.
3. Insert a new or replacement battery in the holder making sure it is held in by
the retainer clips.
4. Plug the battery connector into the socket.
5. Close the processor door.
Installing the SLC 5/03, -5/04, and -5/05 Battery
To install or replace the lithium battery:
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.
IMPORTANT
Battery back-up is optional with the SLC 500 fixed controllers
and the 1747-L511 processors. These processors are shipped
from the factory with capacitor back-up that provides memory
back-up of 5-30 days.
If you are installing a battery in a new processor (battery
never installed before), remove the jumper from the battery
connector socket. Store the jumper in safe place for possible
future use without the battery.
ATTENTION
Do not expose the processor to surfaces or other areas that
may hold an electrostatic charge. Electrostatic charges can
alter or destroy memory.
