Safety requirements
2-4 iRM4451 RRH Product Description and Installation Guide
• Only trained and qualified personnel may install or service equipment
as defined in IEC 215 and EN 60215.
• Turn off or disconnect equipment from its energy source(s) by
switching off the load disconnect switch in the distribution panel before
performing service or maintenance.
CAUTION
LASER RADIATION AND FIBER OPTIC CABLE USE CAUTION!
• Class 1 invisible laser radiation present. Avoid long-term viewing of
laser. Never use a magnifying device to view optical fiber ends when
fiber is connected to equipment.
• Fiber optic cables may be damaged if bent or curved to a radius that is
less than the recommended minimum bend radius of two inches.
Always observe the recommended bend radius limit when installing
fiber optic cables and patch cords.
CAUTION
SHORT CIRCUIT HAZARD!
Condensation on the equipment has a potential to cause short circuits!
Weather conditions may exist at the site where condensation may form on
the equipment. Installing or operating the equipment when condensation is
present may cause a short circuit and damage the equipment.
Equipment showing signs of condensation should be allowed to dry before
installation.
CAUTION
ELECTROSTATICALLY SENSITIVE EQUIPMENT!
Semiconductor components are sensitive to electrostatic electricity and
may be damaged by static discharge.
When handling the equipment, the following rules must be followed:
• Wear conductive or anti-static clothing.
• Wear grounded ESD wrist strap.
• Wear shoes with conductive straps or soles.
• Verify anti-static safety devices are operating properly by testing
yourself at an approved test station.
