should be connected to the grounding screw and the other end of the cable needs to be
earthed. The cross section area of the chassis grounding cable should be more than

, the grounding resistance needs to be <5Ω.
The grounding found on the 5 pin, 5.08mm power terminal block is the surge grounding
connection. The surge grounding and the chassis grounding need to be connected as
