For uncontrolled environments, the level of airborne particulates must not 
exceed 100 µg/m

.

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 81

 for the correct torque setting).

A threaded grounding connector is provided on the rear of the subrack for 
connection to the site ground point (refer to 

“Connection” on page 83

 for 

more details).

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.

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 to secure the subrack 
to the rack or cabinet, and also for the DC input terminals on the PMU

■

Pozidriv PZ2 screwdriver for the M4 screws used to secure the module 
retaining clamps

■

0.25in or 6 mm flat blade screwdriver for the fasteners used to secure the 
front panel to the subrack

■

8 mm AF spanner for the SMA connectors.
