After placement the four legs under the BS can be adjusted for accurate vertical position to
compensate for an uneven floor.
In areas with the possibility of earthquakes, it is recommended that the BS be secured to the
floor with bolts. Access to the base may require removal of the lowest TX combiner in the
rack.

1.3.3 Grounding
The BS requires careful grounding. For temporary operation, the mains earth connection can
be used. For permanent installations an effective ground shall be established and connected
to the grounding screw on the rear right top of the BS with a 15sq. mm yellow/green wire.
Grounding is important to protect the equipment when inserting/removing cables and to
protect the operator from faulty equipment.
An effective grounding is also important to protect the installation during thunderstorm
(lightning).
