The IF and ground cable installation must meet the requirements defined
in Grounding and lightning protection
To provide effective protection against lightning induced surges,
grounding cables must be installed without drip loops and pointing down
towards the ground. To install a cable ground kit at a grounding point,
follow the cable ground kit manufacturer's instructions.
To ensure that IF connections are not damaged by water ingress, all
outdoor IF connectors must be protected from the weather with self
amalgamating and vinyl tape.
Do not connect or disconnect the IF cable when the –48 V supply is
applied to the CMU.
Always ensure the lightning protection units are connected the correct
way round (Figure 5-1).
