Grounding
First attach the two 600 V, 1/0 size cables prepared for grounding to the 2-hole lugs in the accessory kit.
Then lead these grounding cables through the front square hole of the unit base and 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 side wall of the cabinet adjacent to the AC terminals as shown
below:

Note:
The grounding cable only needs a 53.49 ~ 26.67 mm
When multiple cabinets are combined, the grounding cable can be connected one by one. At
this time, there are two grounding cables on the floor.
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.
