Remote units are provided with cooling fins which allow to optimize heat

dissipation. In order to let them work, the environment where the remote unit

is mounted should allow the necessary air changeover. Do not place any

remote unit face downwards on a horizontal surface, because this would

prevent heat dissipation.

Once you have chosen the position of the remote unit, please follow these

steps in order to carry out the installation:

1. Drill into the wall so as to install the M4 screw anchors (not included)

according to the case A or case B layouts indicated by the installation

drawings in fig.3.15 (a)

2. Fix the TFAx remote unit to the wall by firmly screwing the anchors.

3. Take the splice – tray (not included). Fix the splice holder inside the splice

tray. (see fig. 3.10a,b)

4. Splice the optical fibres and close the splice tray. While handling the fibers,

take care of the fiber bending.

5. Fix the splice tray beside the remote unit

6. If the remote unit is -48 Vdc powered, use the -48 Vdc plug (included) in

order to connect the unit to the -48 Vdc mains. If the remote unit is

85/264 Vac-powered, fix the 85/264 Vac plug (included) on to a power cord

(not included), and use this cable in order to connect the unit to the mains.

7. Connect the antenna RF cables to the RF antenna ports. Connect the UL and

DL optical connectors (please refer to fig. 3.4). Apply a 50-Ohm load to the

RF which are no connected to any antenna cable.

8. Once the installation is finished, please follow the section “Start-up for case

A and case B remote units”, in order to carry out a proper system start up.
