2. Prepare OT terminals: M10.
To effectively protect the inverter, two grounding methods must be performed.
Connect the AC grounding cable (Please refer to section 3.4.3)
Connect the external grounding terminal.
1. Prepare the grounding cable: recommend to use the outdoor copper-core cable.
Cable ampacity of the ground conductor should be more than half the ampacity ratings
of AC phase L1,L2,L3 conductors.
To connect the grounding terminal on the heat sink, please follow the steps below:
NOTE
3. Strip the ground cable insulation to a suitable length.
Figure 3.10 Suitable length
For multiple inverters in parallel , all inverters should be connected to the
same ground point to eliminate the possibility of a voltage potential existing
between inverter grounds.
