1. Overview of WTC-LEX/-BEX modules
General description
WTC lighting / sunblind expansion modules
are designed to complement the Water
Terminal Controller with up to eight lighting
and eight shade / sunblind commands.The
expansion modules operate on a separate
sub-bus, giving the controller the ability to
manage lights as well as shades / sunblinds.
The WTC LEX/BEX product line includes
the following modules:
■WTC-LEX-WD/-ST
(4 × 1-10 V dimming lights)
■WTC-BEX-WDLV/-STLV
(4 × 24 V shades / sunblinds)
IMPORTANT: Please note that LEX/BEX
expansion modules are built on a similar platform,
but they have different types and number of inputs
and outputs.
WTC-LEX expansion module is available in
two congurations:
■WD: 100-240 VAC - Quick-connect
(WTC-LEX-WD)
■ST: 100-240 VAC - Detachable
connectors (WTC-LEX-ST)
WTC-BEX LV expansion module is
available in two congurations:
■WD: 100-240 VAC - Quick-connect
(WTC-BEX-WDLV)
■ST: 100-240 VAC - Detachable
Connectors (WTC-BEX-STLV)

Installation requirements
■It is recommended that the expansion
module(s) should be kept at room
temperature for at least 24 hours before
installation to allow any condensation
that may have accumulated due to low
temperature during shipping/storage to
evaporate.
■Upon unpacking the product, inspect the
contents of the carton for shipping damages.
Do not install damaged controllers.
■Avoid areas where corroding,
deteriorating or explosive vapours, fumes
or gases may be present.
■Allow for proper clearance around the
expansion module’s enclosure, wiring
terminals to provide easy access for
hardwarecongurationandmaintenance,
and to ventilate heat generated by the
expansion module.
■Orient the expansion module with the
ventilation slots and power supply/output
terminal block connectors towards the
top to permit proper heat dissipation.
When installed in an enclosure, select one
thatprovidessufcientsurfaceareato
dissipate the heat generated by the
expansion module and by any other
devices installed in the enclosure.
A metal enclosure is preferred.
If necessary, provide active cooling
for the enclosure.
■Do not drop the expansion module or
subject it to physical shock.
■If the expansion module is used and/or
installedinamannernotspeciedby
Carrier Corporation, the functionality
and the protection provided by the
expansion module may be impaired.
■SELV (Separated Extra Low Voltage)
inputs/outputs must be connected to class
3 devices or to SELV sections of class 2
devices.
■If the module is to be mounted on a
metallic support, the same metallic support
is to be connected to a protective earth.
■-WD modules can be wall-mounted or
DIN-rail mounted. Conductors must be
made inaccessible and wiring must
comply with local wiring regulations and
methodsappropriateforxedequipment
installation in a building, e.g. trunking.
■-ST modules without strain relief and
terminal block covers must be wall-
mounted or DIN-rail mounted inside a
supplementary enclosure (rated as IP20
or better) that can only be accessed by
qualiedpersonnel.
■-ST modules with strain relief and
terminal block covers can be only
wall-mountedonaatsurfacethatis
sufcientlylargetoprovidespacearound
the equipment. In this installation
scenario, conductors must be made
inaccessible and wiring must comply with
local wiring regulations and methods
appropriateforxedequipment
installation in a building, e.g. trunking.

2. Mounting instructions
The expansion module can be mounted on a
DIN rail.The module has four mounting
holes 7.2 × 4 mm.The expansion module can
be mounted on a panel or on a wall by using
appropriate screw types (use sheet metal,
thread forming, or self-tapping screws
accordingly).
Turn off the power before any kind of
servicing.
For some models, if the expansion module is
to be installed out of an electrical box, it is a
must to use the optional strain-relief and
terminal block cover.
IMPORTANT: All mountings holes might not be
retrievable on some models. At least two of them
are nevertheless usable in any case.
Wiring recommendations
■All wiring must comply with electrical
wiring diagrams as well as national and
local electrical codes.
■The module must be connected to the
protective earth via its power supply
connector.
■Make sure all wiring is rated at least
250 VAC for -ST and -WD models.
■To connect the wiring to an expansion
module,usethespeciedterminal
connectors.Useasmallatscrewdriver
to tighten the terminal connector screws
once the wires have been inserted (strip
length: 6 mm, tightening torque 0.5 Nm).
■Power cables (i.e. for 2- and 3-wire
voltage and current inputs and outputs, as
well as relay and triac outputs) should be
kept apart from other types of wiring for
safety and to avoid any ambient noise
transmission to other wires.
■Keep all wires away from high speed data
transmission cables (e.g., Ethernet) and
power cables.
■Keep input and output wiring in conduits,
trays or close to the building frame if
possible.
DIN-rail mounted installation
1. Ensure the DIN rail is properly mounted
on the wall.
2. Clip the expansion module onto the DIN
rail.
Wall-mounted installation
1. Use the back plate’s mounting holes to
mark the location of any holes that need
to be drilled.
2. Drill the required holes (at least two
holes).
3. Clean the surface and mount the
expansion module using the appropriate
screw types.

EOL termination:When WTC-LEX/-BEX
expansion modules and room devices are
installed with a WTC controller, only the last
device (expansion module or room device) is
set to ON. All other expansion modules and
room devices must have their EOL
terminations set to OFF.
9. Device addressing
Eachdeviceonthesubnetisidentiedwitha
subnet address.The WTC-LEX/-BEX
expansion module connected to a
controller’s Subnet Port must be set to a
unique subnet ID address.The address is set
through the DIP switch located next to the
Subnet Port connectors.

ThreedifferentSubnetIDcodicationsare
used on the WTC subnetwork:
■1 for Room Control Interfaces
■1 for Infrared Multi-Sensors
■1 for WTC Lighting / Sunblind expansion
modules
Consequently, the same Subnet ID can be
assigned to WTC-LEX/-BEX (Lighting /
Sunblind expansion modules),WTC-ISP/-
ISPL (Infrared Multi-Sensor),WTC-RT
(Room Temperature sensor), or WTC-RCI
series (Room Control Interfaces) without
any addressing issue.

In certain jurisdictions, terminal block covers
are required to meet local safety regulations.
Strain reliefs and terminal block covers are
available for controllers housed in large
enclosures and are used to relieve tension on
the wiring and conceal the controllers’ wire
terminals. Strain reliefs and terminal block
covers are optional and are sold as
peripherals. Strain relief and terminal block
cover usage does not comply with DIN-rail
mounting.
IMPORTANT: Strain relief and terminal block
cover cannot be used with –WD models.
Prior to connecting all wires, it is
recommended to install the strain relief.
Two screws are provided for its installation.
See the bottom part of the enclosure as
presented in Figure 14 below.

Figure 14: Installing the stain relief
Figure 16: Attaching wires to the strain relief
Figure 18: Installing the terminal block cover
Figure 17: Attaching wires to the strain relief
(completed)
If necessary, the terminal block cover can be
clipped on to the strain relief as shown below.
Tie wraps can then be used to group
wires together and attach them securely
to the strain relief in an effort to relieve
the undue tension.
It is recommended to use 4.6 mm wide tie
wraps with tensile strength of 220 N to
attach wires to the strain relief.
Removing the terminal block cove
Toremovetheterminalblockcover,useaat
screwdriver to unclip the terminal cover from
the strain relief.
IMPORTANT:
Turn off the power before any
kind of servicing.

Recommandations de câblage
■ Touslescâblagesdoiventêtreconformes
aux schémas de câblages électriques ainsi
qu'aux codes électriques nationaux et
locaux.
■ Lemoduledoitêtreconnectéàuneprise
de terre via son connecteur
d'alimentation électrique.
■Assurez-vous que tous les câbles des
modèles ST et WD sont de calibre d'au
moins 250 VAC.
■ Pourconnecterlecâblageàunmodule
d'extension, utilisez les connecteurs de
terminauxspéciés.Utilisezunpetit
tournevis plat pour serrer les vis du
connecteur du terminal une fois que les
câbles ont été insérés (longueur de la
bande : 6 mm, couple de serrage :
0,5 Nm).
■Les câbles d'alimentation (par ex. pour
les entrées et sorties de courant et de
tensionà2et3câbles,ainsiqueles
sortiesTriacetrelais)doiventêtre
séparés des autres types de câblage par
sécurité et pour éviter toute transmission
debruitsambiantsàd'autrescâbles.
■Assurez-vous que tous les câbles sont
éloignés des câbles de transmission de
donnéesàhautdébit(parex.,Ethernet)
et des câbles d'alimentation.
■Conservez les câbles d'entrée et de sortie
dans des conduites, des faisceaux ou près
du châssis du bâtiment, si possible.
