4.3 Battery Connection
Before connecting to a battery, please install a separate DC breaker (60A for
Z21I3K6D48 and 120A for Z21I4K6D48) between the inverter and the battery.
This will ensure that the inverter can be securely disconnected during
maintenance.
Be aware of electric shock and chemical hazards!
It is a normal phenomenon that an electric arc occurs when connecting a
battery to the inverter without the use of a DC breaker.
It's very important for system safety and efficient operation to use an
appropriate cable for the battery connection. To reduce the risk of injury,
please use the correct recommended cable size. Refer to Figure 4.3-1.
