Mechanical design and installation
The unit consists of two parts: The base unit and the terminal.
Installation base
The housing of the TLR base unit is a compact enclosure. The controller may be mounted in any orientation by surface
mounting on a wall or in a cabinet with two screws or on a 35mm DIN rail.
When mounting note the following:
•
The controller should not be freely accessible after mounting. A protective housing should be used, if mounted
outside an electrical cabinet.
•
Ensure adequate air circulation to dissipate heat generated during operation
.
•
Local installation regulations must be observed.
Mounting location terminal
•
On an easy accessible interior wall, approx. 1.5 m (4.5’) above the floor in an area of average temperature.
•
Avoid exposure to direct sunlight or other heat sources, e.g. the area above radiators and heat emitting
electrical equipment.
•
Avoid locations behind doors, outside walls and below or above air discharge grills and diffusers.
•
Location of mounting is less critical if external temperature sensors are used
Installation terminal
1.
Install the mounting plate straight to the wall or the flush mounting box. Make sure that the nipple with the
front holding screw is facing to the ground. Make sure the screw heads do not stand out more than 5 mm of
the surface of the mounting plate.
2.
Connect the wires of the terminals to the communication wires according wiring diagram
3.
Slide the two latches located on the top of the front part into the hooks of the mounting plate.
4.
Lower the front part until located flat on the wall and the mounting plate is not visible anymore. Make sure
the connection cable does not get into the way.
5.
With a Philips-type screw driver of size #2, carefully tighten the front holding screw to secure the front part to
the mounting plate. This screw is located on the front lower side of the unit. There is no need to tighten the
screw too much.
Connection base to terminal
•
Max. Distance: 200m (650ft)
•
Normal cables maybe used for wiring in an EMC-save environment. In an impaired EMC environment use only
shielded cables. The operating voltage must comply with the requirements for safety extra-low voltage (SELV)
as per
EN 60 730.
•
One terminal may drive up to 8 base units. See wiring for parallel connections. Total wire distance should not
exceed 200 m (650ft).
•
Conductor resistance will influence external temperature reading. 450
Ω
will result in an increase of 1°C (2°F).
Compensate using UP-08 if external temperature is used to control unit.
