1.5 General Safety Precautions
This equipment contains components that emit laser radiation which can
seriously damage the retina of the eye. Do not look into the ends of any
optical fiber. Do not look directly into the optical transceiver of any digital unit
or exposure to laser radiation may result. An optical power meter or
reflectometer should be used to verify active fibers. Place a protective cap or
lid immediately over any radiating transceiver or optical fiber connector to
avoid potential damage caused by radiation exposure. This practice also
prevents dirt particles entering the openings.
The optical fiber emits radiation. Do not look directly into the ends of an
optical fiber. This may result in exposure to radiation. Do not assume laser
power is turned off or the fiber is disconnected at the other end.
Wet locations and conditions will increase the risk of electrical shock when
installing or using electrical powered equipment. To prevent electrical shock,
never install or use electrical equipment in wet locations or during lightning
storms.
The DHU is powered by 50-88VAC. To prevent electrical shock when
installing or maintaining the DHU, disconnect the wiring at the power source
before working with un-insulated wires or terminals.
The RU is powered by 115VAC. To prevent electrical shock when installing
or maintaining the RU, disconnect the wiring at the power source before
working with un-insulated wires or terminals.
Always consider and allow sufficient fiber length to permit routing or patch
