Remote Unit and its power supply:
• Under no circumstances should any piece of equipment be affected by the heat
created by any other piece. The Remote Unit and its external power supply should be
mounted so as to avoid reciprocal heating. Side-by-side confi guration is suggested (Fig.
3.2.8 a,b)
• It is strongly recommended not to mount the external power supply on a horizontal
surface because this position does not allow for heat dissipation. External power supplies
must be mounted on vertical surfaces.
• In order to assure proper heat dissipation, the external power supplies must be mounted
in a vertical position with the power socket downwards (see Fig. 3.2.8 a,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 TKA04 wall bearing (see Fig.
3.2.12 a)
2. In order to install the M4 screw anchors (included) which hold up the TKA04 wall bearing,
drill into the wall according to the TKA layout shown in Fig. 3.2.11.
3. Fix the TKA04 wall bearing by fi rmly tightening the screws into the anchors.
4. In order to install the M4 screw anchors (not included) which hold up the power supply
external adapter, drill into the wall according to the power supply layout shown in
Fig.3.3.10 b.
5. Fix the external power supply adapter to the wall by fi rmly tightening the screws into the
anchors (Fig. 3.2.13 b).
6. Carefully open the splice tray by using a screwdriver as in Fig. 3.2.12 c. Fix the splice
holder inside the splice tray (Fig. 3.2.6 a). Splice the optical fi bres and close the splice
tray. While handling the fi bers, take care not to bend them. Close the splice tray.
7. Fix the Remote Unit to the wall-bearing by using the included screws (Fig. 3.2.6 b).
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. 3.2.8 b). If the Remote Unit
is 90/264 Vac-powered, fi x the 90/264 Vac plug (included) onto a power cord (not
included), and use this cable in order to connect the external adapter to the mains (Fig.
3.2.8 a).
9. Connect the antenna RF cables to the RF antenna ports. Connect the UL and DL optical
connectors (Fig. 3.2.12 e). If the power cable has properly been connected to the
mains, both the green and the red LEDs should turn on. The green LED will remain lit to
indicate that the unit is powered on, while the red LED will turn off as soon as the local
unit is 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. 3.2.12 f)
