3.2.3 Electrical installation
Statement
：
For Australian market, installations should be conducted in
accordance with AS/NZS 3000 and AS/NZS 5139.
Before connecting the power cables, use multi-meter 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 multi-meter 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. The selection of
the circuit breaker requires:
Current: I =
Inverter power
45V
Voltage: U>60V
For Australian Market, a over-current and isolation device is required between
battery system and inverter.
