Checklist before mounting and installation
• Check that the CI is of the right type. Note that the TTPAs and TTAs must be
connected with different CIs:
TTA: 8478.xx, 8484.xx, 9184.xx or 9221.xx, for 12 VDC
TTPA: 9219.xx, for 48 VDC
• Are the correct cables with the correct connectors and lengths present?
• Is the ground cable present?
• Are straps to secure the CI available?
Installation procedure for CI
Example of CI. Please note that
connectors and connector gender may differ between the versions.
The Current Injector is weatherproof and can be mounted indoors or outdoors. Therre
is no equipment for mounting the CI to walls or antenna tower, as it will form an
integrated part of the TTPA cabling.
With the BTS still active:
1. Connect the antenna cable to the antenna port on the CI.
2. Connect the BTS cable to the BTS port on the CI.
3. Connect the grounding cable to a suitable grounding point (e.g. same as ADPU).
4. Connect the DC cable from the ADPU to the DC port on the CI.
Checklist after mounting and installation
• Check that the grounding straps (if used) are 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)?
• If you are using amalgamating tape to seal off the connectors, check that this is
done.
4. Installation of APDU
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 where the BTS still is active. The BTS then
has to be shut down only once for finishing the installation of all included parts.
