Connecting the ESS

Follow the steps below:
1. Connect the ESS to the ESS (Block C) connector on the Top Bay PDI.
2. Attach the ESS to the back box using metal screws and standoffs.
Connect the rectifier to the Bridge HARN1 connectors on the ESS (Figure 31). The red wire connects to the tab labeled "+" on the
3.
bridge. The black wire connects to the tab labeled "-" on the rectifier. See Figure 30 for the location of the rectifier.
Connect the backup batteries to the Battery connectors on the ESS. The red wire connects to the tab labeled "RED" on the ESS,
4.
the black wire connects to the "BLK" tab. The backup batteries must be wired in series such that you have 24V. Use the white wire
provided to bridge the batteries together. The batteries can be placed on the bottom of the 4010ES back box.
Note:
a. A fused harness is required to connect the backup batteries. That harness is shipped with the panel. The mating
spade lug on the battery should be 0.250 inch x 0.032 inches. If another size is needed, you will need to replace the
battery terminal connectors on the supplied battery harness.
b. One-bay system back boxes support up to 33 Ah batteries. Two-bay system back boxes support up to 50 Ah batteries.
If 50 Ah batteries are used, you must also order the 4100-0650 Battery Shelf.
c. To minimize the power losses due to wiring from the battery box to the 4010ES, use at least a 12 AWG wire and keep
the battery box at the minimum distance possible from the 4010ES.
