4. Siting
• The TRT039N should be located at a position which eases wiring runs
and gives good access for programming.
• It should be mounted approximately 1.5m 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 TRT039N 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 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.
5.7 To reinstall the unit onto the wall plate, first ensure the wall plate
retaining screws are loosened enough to clear the TRT039N body, then
engage the top of the TRT039N onto the wall plate retaining tabs, and
push firmly downwards and then upwards. There will be some resistance
from the terminals.
5.8 Once in place, secure with the retaining screws making sure not to
over tighten.
