equipment model.
Use cables of an appropriate size with respect to the rated absorbed current.
Earth connection must be performed according to the applicable laws.
Special care must be applied to the earth connection of the antenna system since it is
exposed to electrical atmospheric events.
Never forget that despite the earth connection of the equipment frame and the whole
antenna system, it is always dangerous to operate on the equipment in the event of
bad weather with atmospheric discharge. In fact, in the event of high energy discharge
(lighting), the equipment frame can instantly reach very dangerous voltage levels, due
to the earth connection inductance.
For this reason, the equipment should be installed in rooms accessible to maintenance
personnel only and for the time necessary for repairs and checks only.
