10.3. Professional installation

RAy units are only intended for installation by professionally trained people and in locations not access-
ible to the public. Installation and servicing must be carried out by personnel with appropriate technical
training and knowledge of potential hazards.
RAy units shall be installed according to local Electrical Safety Codes. Each person participating on
the installation has to respect all local standards and regulations for personal security and electromag-
netic protection for everybody on the site. We also recommend to consult each site situation with local
experts to ensure both the people and installed equipment are safe, the grounding and other protection
are chosen reasonably for the actual site conditions. Trained staff must check that all parts recommended
by experts regarding grounding and overvoltage protection of sensitive components or infrastructures
are perfectly installed, so they effectively protect the equipment against typical situations.
It is the responsibility of the installer to ensure that all building and safety codes are met and that the
installation is fully completed and equipment properly secured.
