English
Grounding and Lightning Protection
Electrical Ground
(except TB7100
and TB7300)
The 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 the section “Final Reassembly”
in the Installation and Operation Manual 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 the section on connecting the
base station in the Installation and Operation Manual for more details).
Electrical Ground
(TB7100 and
TB7300 only)
A threaded grounding connector is provided on the rear of the tray for
connection to the site ground point (refer to the section on connecting the
base station in the Installation and Operation Manual for more details).
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, we recommend that you conform to your country’s standards
organization or regulatory body.
Equipment Ventilation
Always ensure there is adequate ventilation around the equipment.
Notice Do not operate it in a sealed cabinet. You must keep the
ambient temperature within the specified range, and we strongly rec-
ommended that you ensure that the cooling airflow is not restricted.
Notice All products except TB7100 and TB7300:
Cooling fans are mounted on the front panel and will only operate when
the panel is fitted correctly to the front of the subrack. To ensure ade-
quate airflow through the equipment, do not operate it for more than a
few minutes with the front panel removed (e.g . for servicing purposes).
Notice TB7100 and TB7300 only:
Cooling fans are mounted behind the front panel. To ensure adequate
airflow through the base station, do not operate it for more than a few
minutes with the fans disconnected (e.g. for servicing purposes).
PMU
The only controls on the PMU are the on/off switches on the rear panel for
the AC and DC modules, and the indicator LEDs visible through a slot in
the front panel.
Warning These switches do not totally isolate the internal cir-
cuitry of the PMU from the AC or DC power supplies. You must
disconnect the AC and DC supplies from the PMU before disman-
