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, under any circumstances, be submerged.
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.
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 other 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 center 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 and medical) bands,
which may be used freely (at no cost and with no authorisation required) for industrial, scientific and medical
applications.
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.
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.
