Grounding
Lead the grounding cable through the front square hole of the unit base or through the grounding
cable glands into the PCS cabinet.
Then use a socket or adjustable wrench to connect and secure the grounding cable lugs to the
grounding copper plate at the inner sidewall of the cabinet adjacent to the AC terminals as shown
below:
Figure 39. Grounding Cable Connection with Grounding Copper Bar
Note:
The grounding cable only needs a 35 ~ 50 mm
2
cable.
It’s recommended to connect the protection grounding wires of PCS100HV and battery
cabinet to one bonding point and then grounding to the earth.
Note:
The grounding wire sizing must be larger than half of AC or DC wire sizing.
The wire sizing and ratings are recommended by the manufacturer. If non-recommended
wiring is used, it should comply with local regulations.
