Installation
Mounting and ventilation
Fix the unit to the wall, skirting board, mounting board o similar hard surface. A ventilation gap of at least 25mm
should be left around the front and sides of the unit.
Do not leave the power unit resting on a carpet.
Do not install the power unit where it may become smothered with curtains or other fabrics.
When installing the power unit in a roof space ensure that it will not become buried in thermal insulation
materials.
Signal connections are made to the coaxial sockets on the right-hand side of the power unit. Good quality coaxial
cable to EN50117-2 must be used. Labgear recommend the use of CAI “benched marked” cable.
•
The down lead from the masthead amplifier must be connected to the socket marked ‘IN’.
•
The signal output from the socket marked ‘TV’ is connected to the receiving installation (satellite
receiver, VCR, TV, etc.) or to the input of the cabled distribution system.
Connections
A connection to the PSM114V is made using Type-f (male) connectors. The use of high quality crimp connectors
is preferred and the use of Labgear FPC100 is recommended.
F type connectors should always be tightened with a spanner. Leaving them finger tight may result in unwanted
signal ingress or leakage, as well as suck-outs in the frequency response.
Mains power connections
The PSM114V power unit is fitted with a fitted mains plug and may be plugged directly into a socket outlet.
Alternatively the plug may be cut off and the power unit wired into a fused connection unit, fitted with an approved
3A fuse to BS1362. The PSM114V is a class 2 construction and do not require a protective earth connection. If the
power 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 distribution board of rating no more than 6A.
Short circuit protection
The power supply is protected against output short-circuit by means of a PTC device. Should this protection
operate, 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 trying again.
General Safety notes
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 (IEE Wiring
Regulations).
Distribution systems supplying signals to more than one household should comply with the safety requirements of
BS EN50083-1. This requires the system to be earth bonded or the use of isolated outlets.
General Safety Precautions
The PSM114V are not waterproof and is intended for indoor use only and
must
not
be fixed where they could be
exposed to dripping or splashing water. Objects containing liquids should not be placed on or near the
appliances.
To prevent the risk of fire, objects with naked flames (such as lighted candles) must not be placed on or near the
appliances.
Fitted Mains plug
These appliances are supplied with the standard fused plug already fitted. If this is not suitable, refer to the
instructions below. In the unlikely event that you need to change the fuse in the plug, a 3 Amp fuse to BS1362
carrying the ASTA or BSI approval mark must be used. Always re-fit the plastic fuse carrier when replacing the
fuse.
Changing the Plug
If the fitted mains plug is not suitable for the socket outlets in your home, it should be cut off and an appropriate
new plug fitted.
Wiring the new plug: Any instructions supplied with the new plug should be followed (these may state how
much insulation to remove from the wires in the mains cord). The
Brown
wire must be fitted 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 the 3-pin plug (this appliance does not require an earth connection). Ensure that the cord grip is
the plug is a fused type; the fuse fitted should be rated at no more than 3 Amp.
Caution:
The old plug should be destroyed promptly since it could be dangerous if plugged into a live socket.
