4.6 Grounding
Grounding protects the device from lightning and interference. Therefore, you must ground
the device properly. You need to ground the device before it is powered on and disconnect
the grounding cable after the device is powered off.
There is a grounding screw(see Figure 2) on the top panel of the device. The screw is for
chassis grounding. After crimping one end of the grounding cable to a cold pressed terminal,
secure the end to the grounding screw and firmly connect the other end to ground.
Note:
Cross-sectional area of the chassis grounding cable>2.5mm

; Grounding resistance<5
