Case B
Installation of the Case B Remote Unit WITH the TKA04 installation kit
The TFAx Case B kit includes:
1. a Remote Unit TFAx
2. a 50 Ω load
3. a TPSN external power supply adapter (86 to 264 Vac or -72 to -36 Vdc, according to the
chosen model)
4. a VDE connector or a -48 Vdc plug (according to the chosen model)
The TKA04 kit includes:
A. four screw anchors (fi xing the wall bearing to the wall)
B. fi ve screw anchors (fi xing the TFAx Case B to the wall bearing)
C. a wall mounting box (wall bearing + cover)
D. a splice holder
Please consider these guidelines carefully in order to decide the proper positioning of the
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.
3.3.8 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
Figure 3.3.8:
Example of proper mounting confi guration, which assures proper heat dissipation. Note that the Remote Unit and
its power supply adapter are mounted side-by-side, and the power supply adapter has the socket downwards.
The Figures refer to a 90/264 vac TFAx Case B (a) and to a -36/-72 Vdc TFAx Case B (b), respectively.
