1. If replacing an existing battery in a controller not
currently configured for SRAM usage, backup the
controller's configuration to your PC using the
appropriate WEBs-AX software tool (for example,
2. If a station is running, stop it using the platform
Application Director view.
3. Remove all power from the controller. Wait for all
LED activity to stop (if a battery is already installed,
this may take a minute or two).
4. Remove the cover. See "Removing and Replacing
the Cover" on page 4. Note the Option Slot area
where the NiMH battery assembly mounts.
5. If a battery assembly is already mounted, unplug
the battery from the connector on the controller
board (see Fig. 9).
6. Remove the four screws that secure both option slot
end plates (and if installed, the existing battery
assembly bracket). Set the screws aside.
Remove any existing battery assembly (if applica-
7. Plug the battery connector plug of the new battery
assembly into the battery connector on the control-
ler (see Fig. 9).
8. Set the new NiMH battery assembly on top of the
option card slots, over the option card end plates.
Ensure the bracket mounting holes are aligned with

Battery life expectancy is a function of its discharge cycles
(the number of discharges and their depth) and the
ambient temperature of the battery during normal
operation. In most applications, the NiMH battery should
see relatively few discharges. Therefore, ambient
temperature has more to do with the life expectancy of
the battery than does any other factor. If the controller is
installed in a conditioned space, this battery should
provide dependable service for approximately three years
(average). In an environment where the operating
temperature reaches the highest range (50 ºC or 122 ºF),
you should only expect the battery to last around one
A new NiMH battery is typically only partially charged
when shipped. Additionally, NiMH batteries lose charge
over time if not kept trickle-charged (for more details, see
"NiMH battery pack" on page 13). Therefore, even a new
or replacement battery will require up to 18 hours of
powered operation before it can provide reliable backup
power (is at full charge).
The controller monitors the NiMH battery and periodically
loads the battery to test its ability to maintain battery-
backed functions. Investigate any battery trouble
message, and check the battery connections to the unit.
Replace the battery as required. To order a new battery,

Please dispose of the used NiMH battery in accordance
with local, state, and federal regulations.
