5.6.1 Enabling Depleted Battery Cutout
To enable Depleted Battery Cutout, remove the plastic PCB cover and use a small pair of wire snips to clip the jumper R187 (0 ohm
resistor), which is shown in Figure 27. With this jumper cut, the system shuts down if the batteries reach a depleted state (19.4 VDC).
Note:
Do this only if Depleted Battery Cutout is required. Leave this jumper in place for systems that do not shut down when batteries are
depleted.
The normal default system operation prevents NAC, RAC, and relay operation from initiating after batteries are depleted. That operation
does NOT require jumper removal.
