Note: When setting sense voltages, always adjust the potentiometer until
the sense voltage reading changes, and then set it to the desired voltage.
Additionally, anytime one power supply is adjusted, all other power supply
sense voltages must be re-checked.
4. Once the sense voltages have been balanced, connect the digital voltmeter
to the external battery connector. Verify that voltmeter reading is 54.8
Vdc.
5. If the voltmeter reading is not correct, tweak each of the power supplies
until the voltage reading at the external battery connector is 54.8 Vdc.
Then re-measure the sense voltage on each of the power supplies. Adjust
the power supplies such that the sense voltages are equal by adjusting any
unit with a lower sense voltage up. Once the sense voltages have been
balanced, connect the voltmeter to the external battery connector and
verify the voltmeter reading is 54.8 Vdc.
NOTE: The final value of the power supply sense voltage is not important. As
long as the sense voltages on all power supplies are equal and the voltage
reading at the external battery connector is correct, the unit is properly
adjusted.
7. Replace the front panel.

Re-install the battery fuse and re-connect any external battery packs
