Please consider carefully these guidelines in order to choose a proper
positioning of the remote unit and of its power supply:
o Each piece of equipment should not be affected by the heating of any other
piece. The remote unit and its external power supply should be mounted so
as to avoid reciprocal heating. Side-by-side configuration is suggested (fig.
3.14 a,b)
o It is strongly recommended not to mount the external power supply on a
horizontal surface, because this position does not allow heat dissipation.
External power supplies must be mounted on vertical surfaces.
o In order to assure a proper heat dissipation, the external power supplies
must be mounted in vertical position with the power socket downwards
(see fig. 3.14a,b).
Once you have chosen the position of the remote unit mounting case, please
follow these instructions:
1. Unscrew the 4 screws which lock the lower cover of the TKA01 wall
bearing (see fig. 3.13a)
2. In order to install the M4 screw anchors (included) which shall hold up
the TKA01 wall bearing, drill into the wall according to the TKA layout
shown in fig. 3.15c.
3. Fix the TKA01 wall bearing by firmly screwing the anchors.
4. In order to install the M4 screw anchors (not included) which shall hold up
the power supply external adapter, drill into the wall according to the
power supply layout shown in fig.3.15b
5. Fix the external power supply adapter to the wall by firmly screwing the
anchors.
6. Carefully open the splice tray by using a screwdriver as in fig. 3.13b. Fix
the splice holder inside the splice tray. (see fig. 3.13c). Splice the optical
fibres and close the splice tray. While handling the fibers, take care of the
fiber bending. Close the splice tray.
7. Fix the remote unit to the wall bearing by using the included screws
3.13d.
8. If the remote unit is -48 Vdc powered, use the -48 Vdc plug (included) in
order to connect the external adapter to the -48 Vdc mains (fig. 3.14a).
If the remote unit is 90/264 Vac-powered, fix the 90/264 Vac plug
(included) on to a power cord (not included), and use this cable in order
to connect the external adapter to the mains (fig. 3.14b).
9. Connect the antenna RF cables to the RF antenna ports. Connect the UL
and DL optical connectors (fig.3.13e). If the power cable has properly
been connected to the main, both the green and the red LEDs should turn
on. The green LED will remain on to indicate that the unit is powered on,
while the red LED will turn off as soon as the local unit will be switched on
(for further details about the start up of the system, please refer to the
section “TFAx Case A Start-up”)
10. Fix the lower cover by fastening the 4 screws (fig.3.13f).
