the battery. Also, do not charge, disassemble, heat, place in fire, short circuit, or
solder the battery.
Mishandling of a battery may cause overheating, cracks or ignition which could result in injury and
fire.
Turn off the all lines of the power supply externally when cleaning the module, tightening the terminal
screws or module fixing screws. Not doing so could result in electric shocks.
