Product Safety Information
IMPORTANT: The CD-WAx-00-2 Series Wall Mount CO2 and
Temperature Transmitters are intended to provide an input to
equipment under normal operating conditions. Where failure or
malfunction of the transmitter could lead to personal injury or
property damage to the controlled equipment or other property,
additional precautions must be designed into the control
system. Incorporate and maintain other devices, such as
supervisory or alarm systems or safety or limit controls,
intended to warn of or protect against failure or malfunction of
the transmitter.
IMPORTANT : Le CD-WAx-00-2 Series Wall Mount CO2 and
Temperature Transmitters est destiné à transmettre des
données entrantes à un équipement dans des conditions
normales de fonctionnement. Lorsqu'une défaillance ou un
dysfonctionnement du CD-WAx-00-2
Series Wall Mount CO2 Transmitters risque de provoquer des
blessures ou d'endommager l'équipement contrôlé ou un autre
équipement, la conception du système de contrôle doit intégrer
des dispositifs de protection supplémentaires. Veiller dans ce
cas à intégrer de façon permanente d'autres dispositifs, tels
que des systèmes de supervision ou d'alarme, ou des
dispositifs de sécurité ou de limitation, ayant une fonction
d'avertissement ou de protection en cas de défaillance ou de
dysfonctionnement du CD-WAx-00-2 Series Wall Mount CO2
and Temperature Transmitters.

CAUTION: Risk of Electric Shock.
Disconnect the power supply before making
electrical connections to avoid electric shock.
MISE EN GARDE : Risque de décharge
électrique.
Débrancher l'alimentation avant de réaliser tout
raccordement électrique afin d'éviter tout risque de
décharge électrique.
CAUTION: Risk of Property Damage.
Do not apply power to the system before checking
all wiring connections. Short circuited or improperly
connected wires may result in permanent damage to
the equipment.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas mettre le système sous tension avant d'avoir
vérifié tous les raccords de câblage. Des fils formant
un court-circuit ou connectés de façon incorrecte
risquent d'endommager irrémédiablement
l'équipement.
CAUTION: Risk of Property Damage.
Do not run low voltage cable in the same conduit or
wiring troughs with high voltage wires. Running low
and high voltage wires in the same conduit or wiring
troughs may damage the equipment or cause
system malfunction.
MISE EN GARDE : Risque de dégâts matériels.
Ne pas faire courir un câble basse tension dans les
mêmes gaines ou goulottes électriques que des
câbles haute tension. L'installation de fils basse
tension et haute tension dans les mêmes gaines ou
goulottes électriques risque d'endommager
l'équipement ou de provoquer des
dysfonctionnements du système.

All wiring should conform to local codes and must be
carried out by authorized personnel only. Check all
wiring connections before applying power to the
system.
Make sure that the line power supply is in
accordance with the power supply specified on
page 1.
Short-circuited or improperly connected wires may
result in permanent damage to the equipment.
If you connect more than one transmitter to a single
24 VAC transformer, always connect the phase (~)
to the +Vs connector in each transmitter.
When installing the transmitter, do not touch
exposed contacts on the component board.
When opening or closing the transmitter, avoid
damaging the transmitter electronics with the two
plastic supports on the bottom of the mounting base.
The trimmers only turn 135 degrees each way, less
than half a rotation. Do not force the trimmer past
the stopping point.
Not adhering to these operational instructions could
cause injury or damage the equipment. Retain this
document.

Selecting the Location
The conditions at the location should represent well the area of
interest. Do not install the transmitter on the ceiling. Avoid
placing the transmitter near heat and moisture sources, close
to the discharge of the supply air ducts, and in direct sunlight.
Plan the routing of the cable when selecting the location. You
can bring the cable to the transmitter from above, or from the
center opening of the mounting base.
When bringing a cable through the wall, note that the hole
may also supply air from outside the room into the
transmitter. This may affect the measurement readings. For
example, fresh concrete binds CO2 and may cause low
readings, especially in new buildings. Seal the cable opening
if necessary.

Opening and Closing
To open, use a screwdriver to push down the tab that holds
the transmitter cover and mounting base together. Pull the
mounting base away from the cover, starting from the top.
To close, connect the bottom of the transmitter first, and tilt the
top forward to close the tab. Do not push on the screen.
Closing the transmitter starts it up if power is supplied to the
screw terminals.
