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. The selection of
the circuit breaker requires:
Voltage: U>60V
Current: I =
Inverter power
45V
The circuit breaker is installed between the battery module and the inverter, as shown in Figure
3-4:
1.
Place the B48100 unit on the bracket
as shown in the figure and push the
device into the cabinet at the
installation position. (The cabinet
structure in the figure is for
reference only)
2.
