4.4. Battery Connection
For safe operation and compliance, an individual DC overcurrent protector or disconnection
device is required for the connection of the battery and the inverter. Users are recommended to
utilise a suitable fuse and DC isolator (see next page). In some applications, switching devices
may not be required, but overcurrent protectors must be used. Please refer to the typical am-
perage in the table below for the required fuse or circuit breaker size.
Please follow below steps to implement battery connection:
1. Pass the cable through the terminal:
Reverse Polarity
All wiring/connecting must be performed by qualified personnel. Before making
the final DC connection or closing the DC Breaker/disconnection device, ensure
the inverter unit is wired correctly. A reverse-polarity connection on the battery will
damage the inverter.
