Installation Guide
If the power system is not powered on and does not supply power to any load for more than
two weeks, turn off all battery loops.
Basic Precautions
Before installing and maintaining the battery, note the following:
Short Circuit
Battery short circuit may cause human injuries. Although the voltage of ordinary batteries is
low, the instantaneous high current caused by the short circuit releases a great deal of energy.
There is danger of explosion if the battery is incorrectly replaced. Therefore, replace the
battery only with the same or equivalent type recommended by the manufacturer.
Keep away metal objects, which may cause battery short circuit, from batteries. If metal
objects must be used, first disconnect the batteries in use before performing any other
operations.
