Use a box cutter to strip off a section of the cable sheath. Take care not to damage the shield layer.
Install and waterproof the ground clip. (See the appendix for the waterproofing method.)
Two types of terminals (ground bar terminal and U-shaped terminal) are available for a ground clip.
Select a terminal as required.
• 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.
If the IF cable is longer than 60 m, one more ground point is
required for every extra 30 m.
