Installing a ground clip
Install and waterproof the ground clip. (See the appendix for the waterproofing method.)
Use a box cutter to strip off a section of the cable sheath. Take care not to damage the shield layer.
If a ground clip is installed on a thin cable,
secure the ground clip by using the binding
wire delivered with the ground clip.
For details about how to install ground clips,
see the use instructions delivered with the
ground clips.
Ensure that the angle between a PGND cable and a power cable is
15 degrees or less. If the power cable is routed vertically, route the
PGND cable from the top downwards. Do not route the ground
cable upwards.
