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:
• there is no risk of explosion;
• the environment is not classifi ed as a high-risk one in case of fi re;
• suspended particles are not to be found in great concentration;
• there is no risk of traffi c which could cause collision 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;
• there is no direct sunlight or where water may drip 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 for 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 areas;
• do not install remote units inside cable pipelines or fi re-prevention sites (fi re escapes, lift
tunnelss, emergency exits; which have to guarantee defi ned safety standards);
• take into consideration that the temperature in the upper part of a room is higher than at
the 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;
• each remote unit requires its own power and a connection to the mains might be needed;
