IMPORTANT Notice:
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 are used on unprotected license-free radio bands with radio noise
and interference. The products are designed to operate in the presence of noise and
interference, however in an extreme case, radio noise and interference could 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 E2 Installation Guide.
Check with your local distributor for further information on regulations.
• Operation 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, serial cables and all
terminals of the E2 module should be electrically protected. To provide maximum
surge and lightning protection, the module should be connected to a suitable earth
and the aerial, aerial cable, serial 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 E2 module during
these adjustments. Equipment should carry clear markings to indicate remote or
automatic operation. E.g. "This equipment is remotely controlled and may start
without warning. Isolate at the switchboard before attempting adjustments."
• The E2 module is not suitable for use in explosive environments without additional
protection.
• The E2 Operates unlicensed Radio frequencies and proprietary protocols to
communicate over the radio. 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 you have
considered the security aspects of your installation carefully.
