3. Cable tie the battery harness to the same location previously used for the power supply harness.

4. Install the battery into the cabinet with terminals toward you.

5. Install ring terminal onto the battery terminals (red wire to battery positive +, black wire to battery negative

− battery terminal).

6. Insert Solar and Battery/DC Power fuses into fuse holders on right side of cabinet.

7. Ensure the EMS (Energy Management System) powers up and the OBUI (on board user interface) visibly

lights up. If the EMS does not power up, verify the battery fuse is not blown and the solar polarity is not

backwards.

8. Test system and ensure it is operating as prior to the retrofit:

a. Ensure the solar panel voltage (solr) is between 15 to 20V when it is exposed to sunlight.

b. Run the BIST (built-in self-test) and verify there are no errors, in particular the charging error

(4000).

c. Let the system charge for a few minutes and monitor with a DC voltmeter across the battery (or

view the battery voltage on the OBUI) to confirm battery voltage rises under the battery (batt)

status menu. For 24/7 beacon systems you may need to temporarily change the input (inpt) type

to NO (normally open) or disconnect the LED loads so the system isn't under a constant power

draw.
