General Safety Precautions

• To avoid risk of electric shock during
installation we recommend that the power
unit and all associated TV receivers, etc.
are isolated from the mains until the
installation is complete.
• Fixed wiring for electrical supply to these
products should be carried out in
accordance with BS7671 (IET Wiring
Regulations).
• Distribution systems supplying signals to
more than one household should comply
with the safety requirements of BS EN60728-11.
This requires the system to be earth bonded
or the use of isolated outlets.
