4. Siting
• The TRT030N must be sited where it will not be influenced
by heat sources, for example above a radiator or a television or
a refrigerator/freezer or in direct sunlight or subjected to draughts.
• The product requires air circulation, so do not position above
or below shelving or other wall mounted obstacles.
• It should be mounted approximately 1.5 metres above floor level.
5. Installation
5.1 Ensure the mains supply is switched off and the circuit supply fuses
are removed or the circuit breaker turned off.
5.2 Remove the wall plate from the unit, by undoing the retaining screws,
and pivoting the bottom of the unit outwards. The TRT030N body
can then be lifted off.
5.3 Mark the position of the mounting holes on the wall using the wall plate
as a template. Drill out the mounting holes taking care to avoid any
joists, electrical cables or water/gas pipes that may be hidden beneath
the surface. Insert the rawl plugs into the holes.
5.4 Pass the 230V 50Hz mains supply and load cables through the opening
of the wall plate. Allow sufficient excess cable to wire up the unit, but
not too much to make it difficult to close the unit to the wall plate.
5.5 Fix the wall plate to the wall using the correct mounting screws for the
rawl plugs installed. The retaining screws which secure the unit to the
wall plate should be at the bottom.
5.6 Carefully remove the plastic terminal cover. Terminate the cables into
the terminal block ensuring correct polarity is observed and that all bare
conductors are sleeved (See section 6. Connection Diagram).
Make sure that the curved washer grips the conductor.
Reposition the plastic terminal cover and push into place.
