Grounding and Lightning Protection
1.5.1
Electrical Ground
The TB7100 base station modules are grounded by physical contact
between the module mounting points and the chassis. To ensure a good
ground connection you must tighten each module securely (refer the
Installation and Operation Manual chapter
“Replacing Modules”
for the
correct torque).
A threaded grounding connector is provided on the rear of the tray for
connection to the site ground point (refer to the Installation and Operation
Manual chapter
“Connection”
for more details).
1.5.2
Lightning Ground
It is extremely important for the security of the site and its equipment that
you take adequate precautions against lightning strike. Because it is outside
the scope of this manual to provide comprehensive information on this
subject, we recommend that you conform to your country's standards
organisation or regulatory body.
