Required Equipment

o Digital multi-meter (DMM)

o Adjustment screwdriver

o Previously existing system (MATE3-class system display, HUB communications manager, inverter, and/or charge controller)

Procedure

1. Ensure battery bank is fully charged

2. De-energize system

3. Remove FN-DC

Maintain all wired connections (including green communications cable to HUB)

4. Remove FN-DC front cover

Ensure informational sticker is facing up and terminal block is at the far end

Using the two push tabs, remove front cover

5. Remove red sealant from trim pot for battery (R83, Figure 1 on next page)

6. Energize system

WARNING: Shock Hazard Take all necessary safety precautions when working on energized equipment.

7. Measure battery voltage with DMM at terminals 1 and 2 on FN-DC inputs (Figure 1)

8. Read battery voltage from MATE3 battery screen (seen when the BATTERY soft key is pressed)

9. Adjust trim pot (R83) until the displayed voltage of the FN-DC (from MATE3 display) matches measured battery voltage (measured between terminals 1 and 2 with DMM)

10. Replace front cover

11. Replace FN-DC in system
