5.5 Grounding and Lightning Protection
5.5.1 Electrical Ground
The TB8100 BSS modules are grounded by physical contact between the
module case and the subrack. To ensure a good ground connection you
must tighten each module retaining clamp securely (refer to “Final
Reassembly” on page 97 for the correct torque).
A threaded grounding connector is provided on the rear of the subrack for
connection to the site ground point (refer to “Connection” on page 99 for
more details).
5.5.2 Lightning Ground
It is extremely important for the security of the site and its equipment that
you take adequate precautions against lightning strike. While it is outside
the scope of this manual to provide comprehensive information on this
subject, the following guidelines apply:
install a suitable lightning rod at the top of the tower and connect it to a
secure ground point with appropriate conductors and connectors
position site buildings and equipment within the cone of protection
provided by the grounded tower
protect all cables entering the site to prevent lightning energy from
entering site buildings.
5.6 Recommended Tools
It is beyond the scope of this manual to list every tool that an installation
technician should carry. However, the following tools are specifically
required for installing the TB8100 BSS:
Pozidriv PZ3 screwdriver for the M6 screws used in the DC input
terminals on the PMU; M6 screws are also used to secure the subrack to
the cabinet in Tait factory-assembled systems
Pozidriv PZ2 screwdriver for the M4 screws used to secure the module
retaining clamps
0.25in or 6mm flat blade screwdriver for the fasteners used to secure the
front panel to the subrack

You can also obtain the TBA0ST2 tool kit from your nearest Tait Dealer or
Customer Service Organisation. It contains the basic tools needed to install,
tune and service the TB8100 BSS.
