Figure 5.7 Schematic diagram of cabinet grounding
Ground flat steel
Fix the grounding flat steel to the two grounding points of the energy storage and battery cabinet
base with M10x30 screws, the whole fixing surface needs to be sprayed after completion.
Grounding cable
Use a 25 mm² to 50 mm² grounding cable to reliably connect the two grounding points of the
energy storage cabinet and the battery cabinet to the grounding point of the grounding grid on site.
The cable is crimped to the DT terminal and when crimping is complete, it is tightened using
M10x30 screws.
Please take into account the actual situation of the project site and follow the instructions of the
power station staff to install the external grounding. The grounding resistance shall be measured after
the grounding connection is completed, and the resistance value shall not be greater than 4Ω.
5.4 Cable wiring between cabinets
The parallel cabinet cable wiring only happens when the energy storage cabinet and the battery
cabinet are connected together. The cabinet cables wiring including DC power cable wiring and
signal cable wiring, and these cables are shipped with the cabinets and has plug-in connection .
