THREE PHASE HI 8~12kW | Installer Manual17
Please follow the below steps to implement battery connection:
1. Please choose a suitable battery cable (appropriate rating) with the correct connector to attach to the
battery terminals.
2. Use a suitable screwdriver that matches the bolt size to unscrew the bolts to t the battery connectors.
Then tighten the bolts with the connectors in place with a torque of 24.5N.m in a clockwise direction.
3. Make sure the polarity is correct at both the battery and inverter terminals.
Battery Connection
For safe operation and compliance, an individual DC overcurrent protector or disconnection device is
required to connect the battery and the inverter. Users are recommended to utilise a suitable fuse and DC
isolator (see next page). Switching devices may not be required in some applications, but overcurrent pro-
tectors must be used. Please refer to the typical amperage in the table below for the required fuse or circuit
breaker size.

Pass the battery power cable
through the magnetic ring and
wrap it around the magnetic
ring two times.
Pass the BMS communication cable
through the magnetic ring and wrap
it around the magnetic ring four times.
WARNING
Reverse Polarity.
Before making the nal DC connection or closing DC breaker/disconnect, be sure positive (+) must be
connected to the positive (+) and negative (-) must be connected to the negative (-). A reverse polarity
connection on the battery will damage the inverter.
All wiring/connecting must be performed by qualied personnel. In addition, connecting the battery
with a suitable cable is essential for safe and ecient operation of the system
