4.4.2 System connection
Ø
Before installing in series, make sure that the voltage difference of the
battery pack must be less than or equal to 0.5V.
Ø
When connecting the power line, it must be the same color terminal to
connect and then use it together, otherwise there may be dangers such
as short circuit on the side.
Ø
A DC circuit breaker has been installed in the High voltage controller, It
is not recommended to install a DC circuit breaker between the battery
system and the hybrid inverter system, If you want to install a DC circuit
breaker, do not operate the DC circuit breaker with power on, otherwise
the machine may be damaged. And then you need to purchase it yourself
according to the following specifications:
a. Voltage: 1000Vdc
b. Current: 63A

A. BDC 95045-A1 (High voltage controller) wiring
Step 1: Insert the power cable into the corresponding port, then there is click sound
indicating the connection is ok.
Step 2: Insert the communication cable into the "INV port" and "BMU port", and then
tighten the communication terminal clockwise. INV communication port is used for
communication connection with hybrid inverter, BMU communication port is used for
communication connection with battery pack.
Ø
For a single cluster battery system, the “Link-in” and “Link out” port
of the BDC 95045-A1 don't need to be connected, they are only used for
parallel connection of the battery systems.
Ø
Please pay attention to the connector color when connection the
power line. Only the same color of the connector could be connected
together.
Ø
To ensure system security, do not forget to install ground wire.
Ø
This area is a restricted access area , which is explained below:
area accessible only to electrically skilled persons and electrically
instructed persons with the proper authorization.
