After the battery installation and connection done, check if BAT+ to N & N to BAT- voltages are correct with multi-
meter or other equipment. Install the cover if the voltages are correct.
Note: Battery "+" "-" poles cannot be reversed, also cannot short the battery "+" "-" poles, otherwise batteries
would be damaged or other accidents would happen. Don't touch the battery "+" "-" poles at the same time. It's
better only single man make the operation.
