Important Notice
WESTERMO products are designed to be used in industrial environments, by experi-
enced industrial engineering personnel with adequate knowledge of safety design
considerations.
WESTERMO 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, WESTERMO 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 ade-
quate 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 WESTERMO Technologies first.
1. A radio license is not required in some countries, provided the module is installed
using the aerial and equipment configuration described in the RM-80 Installation Guide.
Check with your local distributor for further information on regulations.
2. 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.
3. To avoid the risk of electrocution, the aerial, aerial cable, serial cables and all terminals
of the RM-80 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.
4. To avoid accidents during maintenance or adjustment of remotely controlled equip-
ment, all equipment should be first disconnected from the RM-80 module during
these adjustments. Equipment should carry clear markings to indicate remote or auto-
matic operation. E.g. “This equipment is remotely controlled and may start without
warning. Isolate at the switchboard before attempting adjustments.”
5. The RM-80 module is not suitable for use in explosive environments without addi-
tional protection.
