Mains supply connection and safety notes:
The starBOX is supplied with a fitted mains plug and may be plugged directly into a 13 A (BS 1363) socket
outlet. If socket outlets of a different type are in use, please refer to the safety instructions on page 11.
The mains plug should remain readily accessible to permit disconnection of the unit from the supply.
Alternatively the plug may be cut off and the amplifier wired into a readily accessible fused connection
unit, fitted with an approved 3 A fuse to BS 1362. This method of connection is recommended for
permanent distribution system applications, since it reduces the risk of tampering and accidental
disconnection.
If the unit is not connected to the mains using the fused plug supplied, or a fused connection unit, it must
be protected by means of a fuse or MCB at the final distribution board of rating not exceeding 6 A. A
readily accessible local isolating switch should be provided to allow the unit to be disconnected from the
supply when necessary. Any fixed wiring installed to supply power to this starBOX should comply with BS
7671 (IEE wiring regulations) and, where relevant, Part P of the building regulations. StarBOXs are of Class
2 construction and do not require a protective earth connection. This does not obviate the need to
provide a circuit protective (earth) conductor in the supply wiring, as required by BS 7671.
System equipotential bonding:
Distribution systems supplying signals to more than one household should comply with the safety
requirements of BS EN 60728-11. This effectively requires earthed equipotential bonding of the system.
(Isolated outlet plates cannot be used with starBOX units for functional reasons.) Although not mandatory
in single households, the use of system earth bonding is strongly recommended for all installations. All
starBOXs are provided with an earth terminal. A bonding conductor of 4 mm² should be provided,
connected to the main earth terminal of the electrical installation which supplies the unit. Bonding may be
affected by using earth bonding bars.
User's equipment connections
Master location:
Figs.1 and 2 show typical wiring diagrams for the user's equipment at the master location. Some points to
note are:
•
When using Sky*-only remote control from the extension rooms, the RETURN connection to the
master outlet plate must come directly from RF OUT-2 of the Sky receiver (Fig. 2). RF OUT-1 should be
connected to the local main TV. The starBOX provides 9 V DC power for remote receiver eyes on all
extension room outputs. Note that some Sky receivers require their RF OUT-2 power option to be
enabled in order for remote control extension to work. On the Sky handset press SERVICES, 4, 0, 1,
SELECT, then select the SECOND OUTLET POWER SUPPLY option. Set this to be ON, SAVE SETTINGS
and BACK UP out of the menu.
•
TV signals (UHF) will only be available in the extension rooms if a feed is provided to the UHF RETURN
connection (see explanation above in the Principles section). If no remote control extender system is
to be used, a two-way passive splitter should be employed if necessary to split the RF output from the
final item in the UHF loop-through chain, with one leg of the splitter connected to the main TV and
the other leg feeding UHF RETURN.
•
If no equipment is in use at the master location connect a short lead between the TV and RETURN
connectors at the master outlet (or between MASTER OUT and UHF RETURN at the starBOX itself) to
provide TV signals in the extension rooms.
Extension rooms:
Fig.3 shows a typical extension room installation with an infrared receiver eye. Points to note when using
remote control extension are:
•
Any signal outlet plate used must be non-isolated and must provide DC continuity to the TV outlet to
enable power from the starBOX to reach the receiver eye.
