4.5 Cables connections
Keep the following tips in mind when laying cables:
- Do not tie the cables for the radar together with cables of other equipment, especially the power
supply cable.
- If you need to pass the cable through a wire chase or conduit, tape the scanner side connector to
the wire so it doesn't pull off or get hung up.
-
Secure cables in place at intervals of about 40 cm (16").
