Required tools to ground Zebra 3S

1x Screw M4X10mm (

A

in figure 14) - The screw must be long enough to hold the washers and lug, but not too long since the hole is blind and has limited depth.

1x Flat washer (4 mm hole) (

B

in figure 14) - it will make a hard support for a soft cable lug. It will improve the contact quality.

1x Cable lug (4 mm hole) (

C

in figure 14) - 2.5-6mm cable (according to the cable used). Lug will manage a good contact between our device and the cable. Lug cable size must be chosen properly, otherwise, the cable won't hold well and the contact will be poor.

1x Fan washer (4 mm hole) (

D

in figure 14) - this one will bite through aluminum anodization and make good conductive contact.

Screwdriver which will fit the used screw-head.

Lug/cable crimping tool.

AWG11 Copper-stranded wire of the required size (the shorter the better). Use yellow/green stripe-colored wire since this is the color of a protective conductor according to IEC 60446 standard.
