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 315-WH-Series 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
315-WH-Series 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 315-WH-Series 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 315-WH-Series module is not suitable for use in explosive environments without additional
protection.
 The 315-WH-GT 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.
