Battery Installation and Replacement Considerations
The following procedure describes the installation of a battery.
Installing/Removing a Battery
The following procedure describes how to install or remove a battery.
Step Action
1 Remove the insulating strip from the plus (+) pole of the battery before inserting it
into the module. This strip is used to insulate the battery when on the shelf. Note:
The battery installed in the module, when shipped, has the insulating strip in place.
Remove this strip and re-install the battery before operation.
2 When single battery backup is required, install the battery in Battery Slot 1. The
circuitry is designed so Battery 1 supplies the current until it is used up. Battery 2
(when installed) then assumes the load requirement without interruption. Battery
status is indicated via LEDs and Modsoft status bytes.
3 When the controller is in operation, the batteries can be replaced at any time. Note:
When the controller is powered OFF, battery replacement can be done without RAM
loss only when a second functioning battery is installed.
Step Action
1 Remove the insulating strip from the new battery.
2 If necessary, remove the old battery. Detach it from its housing (on the front of
the module), by pulling the battery access strip (see below) until the battery pops
out.
3 Replace it with the new battery using the reverse of the procedure in step 2.
