should consider alternatives to batteries such as backup generators.
WARNING: Do not touch exposed metal parts with battery leads. Turn off (Shut) branch
circuit power before installing or servicing equipment. Be aware that while making the
battery connections to the LPS5, sparking may occur.
To connect batteries in series one "Negative," typically black, (-) terminal from one battery
would connect to the "Positive," typically red, (+) terminal of the second battery.
The remaining negative and positive terminals would connect to the "BAT" screw terminals
located next to the "AC" LED on the LPS5. The positive terminal is on the left and negative
on the right regarding the PCB "BAT" label.
