Connect mains input to pin 1 and 2. To use a lead-acid backup battery, connect it to pin 3 and 4,
otherwise leave pin 3 and 4 unconnected. To use a NiMH (Nickel Metal Hydride) battery for back-
up, a Micronix PV-1075 can be integrated in the PC/104 stack. In this case, see documentation
supplied with PV-1075 for connection of mains and battery.
KL3
Output power can be supplied from connector KL3. This should be used if the output current
exceeds the PC/104 connector limits, see section PC/104 connector (CN1), or if you need power for
devices that are not powered through the PC/104 bus.
