6.2. Installation Site Features
A trained technician should carry out the installation of the master unit. Since
the system is designed for indoor installation, the master unit should be
installed in a dry and suitable location where:
• no explosion risks is present;
• the environment is not classified as a high-risk one in case of fire;
• suspended particles are not to be found in great concentration;
• the environment is not subject to any traffic which could cause crash
damages;
• the site is properly located with respect to the ergonomic positioning of the
working environments;
• the system is placed in a private room, protected against any possible
violation;
• do not install the system in direct sunlight or in place where water may
drop on the device (for example under air-conditioning equipment).
• the site must be accessible by maintenance personnel;
• the site must be dry, with low humidity;
• the site must guarantee proper space for cables and natural ventilation to
the system;
• 2 meters must be kept between the rack and any heating opening.
The remote units should be mounted in reasonable locations as well:
• do not install remote units inside heating or conditioning;
• do not install remote units inside cable pipeline or fire-prevention site (fire
escape, lift tunnels, emergency exits, which have to guarantee defined
safety standards);
• keep into consideration that the temperature in the upper part of a room is
higher than at 2 meter height. For false ceiling installation of case-A and
case-B remote units, verify that the environment temperatures do not
exceed allowed limits;
