Installation Instructions
ErP Compliant In Line Power Supply
PSM114E/S - 12VDC 100mA power supply with Type-F connections
The PSM114E/S is a 12VDC regulated power supply ideal
for powering any masthead amplier, or a number of
masthead ampliers in cascade, providing the total
current demand is not more than 100mA.
The power supply complies with the ErP (Energy Related
Products) Directive. This means that when there is no load
the power used is less than 0.3W and the energy eciency
in use complies with the directive.
Fix the unit to the wall, skirting board, mounting board or
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 amplier must be connected to the socket marked “AMP”.
•
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.
A connection to the PSM114E/S is made using Type-f (male) connectors. The use of high quality crimp connectors
is preferred. F type connectors should always be tightened with a spanner. Leaving them nger tight may result in
unwanted signal ingress or leakage, as well as suck-outs in the frequency response.
The PSM114E/S power unit is tted with a moulded mains plug and may be plugged directly into a socket outlet.
Alternatively the plug may be cut o and the power unit wired into a fused connection unit, tted with an approved
3A fuse to BS1362. The PSM114E/S is of a class 2 construction and does 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.
The PSM114E/S has automatic short circuit and overload protection and will cut out automatically when either is
detected. Reset is automatic when the problem is resolved.
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.
