Safety Instructions
Overheating:
These amplifiers are intended for use in moderate climates only. They should not be used in tropical
regions. The recommended ventilation clearances and other precautions given in the relevant section of this
instruction leaflet should be observed to prevent overheating. No unit should be fixed where it is likely to
become smothered by soft furnishing fabrics such as curtains, or by thermal insulation material in a roof
space or building void. Mains powered equipment should not be left resting on a carpet
Water and fire risks:
The power supply is not waterproof. It is intended for indoor use only and must not be fixed where it could
be exposed to dripping or splashing water. Objects containing liquids should not be placed on or near the
appliance. To prevent risk of fire, no object with a naked flame should be placed on or near any of the
appliances, or its associated wiring.
Mains plug and disconnection from the supply:
The appliance is supplied with a standard fused plug fitted. If this is unsuitable, refer to the instructions
below. If you need to change the fuse in the fitted plug, a 3 Amp fuse to BS 1362 carrying the ASTA or BSI
approval mark must be used. Always replace the plastic fuse carrier when renewing the fuse. The plug (or
other means of disconnection from the supply, if used) should remain readily accessible for operation when
necessary. The LED power indicator on this equipment should not be regarded as providing reliable
indication of supply disconnection.
Changing the plug:
If the fitted mains plug is not suitable for the socket-outlets in use, it should be cut off and a new plug fitted...
Wiring the new plug: Instructions supplied with the new plug should be followed. The brown wire must be
connected to the live (L) terminal of the plug and the blue wire to the neutral (N) terminal. Neither wire
should be connected to the earth (E) terminal of a 3-pin plug (the appliance does not require an earth
connection). Ensure that the cord grip in the plug is correctly used and clamps the sheath of the cord firmly.
Fuse Rating: If the new plug is a fused type, the fuse fitted should be rated at not more than 3 Amp.
Caution: The old plug should be destroyed immediately since it would be dangerous if plugged into a live
socket.
System equipotential bonding:
Distribution systems supplying signals to more than one household should comply with the safety requirements
of EN 60728-11. This effectively requires earthed equipotential bonding of the system. (The use of isolated
outlet plates is no longer recommended since they compromise screening integrity and allow ingress of
interference.) Bonding may be effected using a PROBAR equipotential bonding bar.
Output protection:
The power unit is internally protected against output short-circuit. If this protection operates, the power indicator
LED colour will change from green to red to indicate a fault condition. To reset the protection, disconnect the unit
from the mains and allow at least one minute for cooling before re-applying power.
