Be sure the system is turned off during the installation process.
Remove the cover by loosening the two bottom screws with a philips head
screwdriver (the screws remain in the cover to avoid misplacing them). Pull the
cover away from the KSU and lift upward.
Remove the screw that is attached to the grounding cable and loosen the second
screw that secures the metal plate to the batteries. Slide the metal plate until it
clears the remaining screw and lift upward to remove the metal plate.
If replacing existing batteries, detach the battery cables from the connector
terminals CN3 (BATT1) and CN4 (BATT2). Lift out the old batteries.
Insert the new batteries into the slots. Place the notched end of the battery toward
the casing on the KSU. Place the battery cables between the inside of the battery
and the posts located on the inside of the battery casing.
