Environmental recommendations
a. Explosive atmosphere
Except for the ACW-ATEX line specifically intended for this purpose, do not use ACW radio modems in the presence of
flammable gases or fumes. Using the equipment in such an environment constitutes a safety hazard.
b. Environment
Respect the temperature ranges for storage and operation of all products. Failing to respect these guidelines could
disrupt device operation or damage the equipment. ACW products in IP65 water- and dust-resistant housings may be
placed outdoors but must not be submerged under any circumstances.
Follow the instructions and warnings provided below to ensure your own safety and that of the environment and to
protect your device from any potential damage.

ATIM_ACW-THAQ_UG_EN_V1.7
General hazard –Failure to follow the instructions presents a risk of equipment damage.
Electrical hazard –Failure to follow the instructions presents a risk of electrocution and
physical injury.
Direct-current symbol
WARNING: do not install this equipment near any source of heat or any source of humidity.
WARNING: for your safety, it is essential that this equipment be switched off and disconnected from
mains power before carrying out any technical operation on it.
WARNING: the safe operation of this product is ensured only when it is operated in accordance with
its intended use. Maintenance may only be performed by qualified personnel.
Waste disposal by users in private households within the European Union. This symbol appears on a
product or its packaging to indicate that the product may not be discarded with another household
waste. Rather, it is your responsibility to dispose of this product by bringing it to a designated
collection point for the recycling of electrical and electronic devices. Collection and recycling waste
separately at the time you dispose of it helps to conserve natural resources and ensure a recycling
process that respects human health and the environment. For more information on the recycling
centre closest to your home, contact your closest local government office, your local waste
management service, or the business from which you purchased the product.
c. Radio
Modems in the ACW line are radio-communication modems that use the ISM (industrial, scientific, andmedical) bands,
which may be used freely (at no cost and with no authorization required) for industrial, scientific, and medical
applications.

IMPORTANT NOTE
The VOC index represents the overall concentration of all VOCs (volatile organic compounds) and not a specific concentration
of a given compound. The index is defined on a scale from 0 to 500 (0 for almost zero VOC concentration and 500 for very high
VOC concentration).
The scale (unitless) below provides an approximate representation based on colours:
CO2
Range
0 to 40.000 ppm
Resolution
1 ppm
Precision between 400 ppm and 5000 ppm
± 40 ppm (+ 5 % of the measurement)
IMPORTANT NOTE
The CO2 measurement represents the concentration of carbon dioxide in the ambient air. In general, the measurement will
rarely drop below 400 ppm, this value being the minimum detection threshold in the outside air.
Here is an informative table providing air quality zones according to CO2 concentration:

Casing
a. Space requirements
b. Mounts to
ACW-THI modems are attached to a wall with two screws that fit into the two mounting holes on the back of the box.
The vents on the cover must be on
the right, in the same direction as
the photo opposite.
Match the pivots at the top of the
case base with their respective
locations on the back face.
To remove the two faces, place a
screwdriver in one of the two fixing
areas at the bottom * of the front
face and press inwards until the
cover is released from the base.
* It is imperative to open the case from below; opening from the top can
damage the circuit.
