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.
