Safety & Certification Notice
“Only qualified personnel should handle the DAS equipment. Any person involved in
installation or service of the DAS should understand and follow these safety guidelines.”
- Obey all general and regional safety regulations relating to work on high voltage installations,
as well as regulations covering correct use of tools and personal protective equipment.
- The power supply unit in repeaters contains dangerous voltage level, which can cause electric
shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to
be followed when servicing repeaters.
- To prevent electrical shock, switch the main power supply off prior to working with the DAS
System or Fiber BDA. Never install or use electrical equipment in a wet location or during a
lightning storm.
- When working with units outdoors, make sure to securely fasten the door or cover in an open
position to prevent the door from slamming shut in windy conditions.
- Use this unit only for the purpose specified by the manufacturer. Do not modify or fit any spare
parts that are not sold or recommended by the manufacturer. This could cause fires, electric
shock or other injuries.
- Do not operate this unit on or close to flammable materials, as the unit may reach high
temperatures due to power dissipation.
- Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or
abrasives on the DAS equipment. Alcohol may be used to clean fiber optic cabling ends and
connectors.
- Do not look into the ends of any optical fiber or directly into the optical transceiver of any
digital unit. Use an optical spectrum analyzer to verify active fibers. Place a protective cap
over any radiating transceiver or optical fiber connector to avoid the potential of radiation
exposure.
- Allow sufficient fiber length to permit routing without severe bends.
- For pluggable equipment, make sure to install the socket outlet near the equipment so that it
is easily accessible.
