3.2.3 Electrical installation
Before connecting the power cables, use multimeter to measure cable continuity,
short circuit, confirm positive and negative, and accurately mark the cable labels.
Measuring methods
：

Power cable check: select the buzzer mode of multimeter and detect the both
ends of the same color cable. If the buzzer calls, it means the cable is in good
condition
.
 Short circuit judgment: choose multimeter resistor file, probe the same end of
positive and negative pole, if the resistor shows infinity, means that the cable
is available.

After visual testing of power line connection, the positive and negative poles of
the battery shall be connected respectively to the positive and negative poles
of the opposite terminal
.
It is better to add a circuit breaker between the inverter and the battery system.
