Important Notices
ELPRO products are designed to be used in industrial environments by experienced industrial engineering personnel with adequate knowledge of safety design considerations. ELPRO radio products can be used unprotected license-free radio bands with
radio noise and interference. The products are designed to operate in the presence of noise and interference, but in an extreme case radio noise and interference can cause product operation delays or operation failure. Like all industrial electronic
products, ELPRO products can fail in a variety of modes due to misuse, age, or malfunction. We recommend that users and designers design systems using design techniques intended to prevent personal injury or damage during product operation and
provide failure tolerant systems to prevent personal injury or damage in the event of product failure. Designers must warn users of the equipment or systems if adequate protection against failure has not been included in the system design. Designers must
include this Important Notice in operating procedures and system manuals. These products should not be used in non-industrial applications, or life-support systems, without consulting ELPRO first. A radio license is not required in some countries,
provided the module is installed using the aerial and equipment configuration described in the Installation Guide. Check with your local distributor for additional information on regulations. Operation of unlicenced equipment is authorized by the radio
frequency regulatory authority in your country on a non-protection basis. Although all care is taken in the design of these units, there is no responsibility taken for sources of external interference. Systems should be designed to be tolerant of these
operational delays. To avoid the risk of electrocution, the aerial, aerial cable, data/IO cables and all terminals of the module should be electrically protected. To provide maximum surge and lightning protection, the module should be connected to a suitable
ground and the aerial, aerial cable, IO, data cables and the module should be installed as recommended in the Installation Guide. To avoid accidents during maintenance or adjustment of remotely controlled equipment, all equipment should be first
disconnected from the module during these adjustments. Equipment should carry clear markings to indicate remote or automatic operation. For example:
“This equipment is remotely controlled and may start without warning. Isolate at the switchboard
before attempting adjustments.
” The equipment operates unlicensed radio frequencies, proprietary protocols to communicate over the radio, cyber security features and encryption. Nevertheless, if your system is not adequately secured, third parties may
be able to gain access to your data or gain control of your equipment via the radio link. Before deploying a system, make sure that you have carefully considered the security aspects of your installation and read the user documentation.
Proper Use
Any unauthorized modifications to or use of this equipment outside its specified mechanical, electrical, or other operating limits may cause personal injury and/or property damage, including damage to the equipment. Any such unauthorized modifications:
(1)
constitute “misuse” and/or “negligence” within the meaning of the product warranty, thereby excluding warranty coverage for any resulting damage; and (2) invalidate product certifications or listings.
