to disconnect the feeder and adapter cable from the antenna and attach it to the
TTPA. Then connect the TTPA to the antenna using the short cable. If the feeder
is attached directly to the antenna, or is easy to move, then it may be connected
directly to the TPPA. Always first attach the cables to the connectors by hand,
then use the torque meter to tighten the cables to 25 Nm. It is important that the
torque does not exceed 30 Nm because of the risk of damage to the connectors.
make sure that the antenna cable is connected to the ANT connector, and the BTS
cable to the BTS.
Checklist after mounting and installation
• Check that the brackets or wall holders are properly tightened.
• Are the grounding straps connected and the screws tightened?
• Are all 7/16 connectors connected and tightened to 25 Nm (or by hand, if no
torque meter is available)?
• Check that the feeder has not been forced to connect to the TTPA.
• Applicable if no CI is used: Are the DC cables connected to the TTPA DC
connectors?
Note: The TTPA must be powered on within one day after unpacking and mounting,
to prevent malfunction and damage due to moisture.
3. Installation of CI
General
Note that at some stages during the installation, the BTS must be turned off. To
prevent extensive downtime it may be useful to finish the first stages of the
installation of both TTPA, APDU and CI when the BTS still is active. The BTS then
has to be shut down only once for finishing the installation of all included parts.
Outdoor and indoor conditions
The CI can be installed both indoors and outdoors. Normally, it will be strapped to a
cable ladder or equivalent. It is environmentally protected (IP 65), and can be
mounted without any kind of protection from bad weather conditions. However, it is
not permitted to install the CI outdoors in bad weather conditions. If the bad weather
conditions are of a short duration, and the CI and all other connectors that are to be
connected during the installation are protected, the installation may continue not less
than one hour after the adverse conditions have ended.
Information on environmental requirements for the CI is found in the Reference
Manual.
