3. INSTALLATION & SAFETY REQUIREMENTS
3.1. Environmental conditions:
This equipment is designed to be installed inside buildings. Operating temperature: +5 to +40°C
Do not install in corrosive atmosphere or in critical environmental conditions such as hazardous classified areas (for example see appendix C).
3.2. Installation site features
A trained technician should carry out the installation of the donor rack. Since the system is designed for indoor installation, the rack 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;
• the system must not be exposed to ultra-violet rays;
• 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 from the rack to any heating opening.
The remote units should be mounted in reasonable locations as well:
• do not install inside heating or conditioning;
• do not install inside cable pipeline, 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 meters height. For false ceiling installation, verify that the environment temperatures do not exceed allowed limits;
• remote unit requires its own power and a connection to the mains can be needed;
• keep into consideration that the remote unit transmits RF signal and safety volume must be respected (refer to country regulations for safety volume magnitude);
• remote units are typically installed next to the ceiling and for safety reasons they must be properly mounted;
• remote units must be accessible for tests and maintenance.

3.3. Power connection
Power connection has to be carried out following all the necessary precautions:
• it must be properly made according to the due diligence rules (ex.: CEI rules, IEC rules, etc.);
• in accordance with the rules for safety against direct or indirect contacts;
• in accordance with the rules for safety against the over current (short circuit,
overloading);
• in accordance with the rules for safety against over tension;
• connection is to be carried out by proper and competent staff
3.4. Safety and precautions during the installation
During installation the following means and tools will be needed:
Typical electrician tools: cross-point screwdriver, scissors, pliers, nippers, drill and bits, screw for fixing remote units to the wall.
Typical means:
proper ladder, scaffolding or air platform for ceiling installation of remote units.
N.B: cautions should be used when installing at a height upper than 2 meters.
9
Personnel who are installing this equipment should be informed about the possible risks and safety measures when elevated.
3.5. Safety and precautions for lasers
The laser used in Britecell contains an optical transmitter, which has a power level that is not dangerous to a person's health. However it is classified as class III B (norm EN60825) equipment. It is nevertheless prudent in the installation phase to observe the following rules:
Never look directly at the internal optic connector exit of the transmitter
9
apparatus when it is switched on. The wavelength of the laser is not visible to the human eye, which means that long-term damage will not immediately be known.
9
When working with the optical connectors, check at each end that both transmitting lasers are switched off.
