ADMONISHMENTS

Important safety admonishments are used throughout this manual to warn of possible hazards

to persons or equipment. An admonishment identifies a possible hazard and then explains

what may happen if the hazard is not avoided. The admonishments — in the form of Dangers,

Warnings, and Cautions — must be followed at all times. These warnings are flagged by use

of the triangular alert icon (seen below), and are listed in descending order of severity of

injury or damage and likelihood of occurrence.

Danger: Danger is used to indicate the presence of a hazard that will cause severe personal

injury, death, or substantial property damage if the hazard is not avoided.

Warning: Warning is used to indicate the presence of a hazard that can cause severe

personal injury, death, or substantial property damage if the hazard is not avoided.

Caution: Caution is used to indicate the presence of a hazard that will or can cause minor

personal injury or property damage if the hazard is not avoided.

GENERAL SAFETY PRECAUTIONS

The following general admonishments apply throughout the procedures in this manual.

Warning: Wet conditions increase the potential for receiving an electrical shock when

installing or using electrically-powered equipment. To prevent electrical shock, never install

or use electrical equipment in a wet location or during a lightning storm.

Warning: Do not install the DRU in marine, industrial, or Intrinsic Safety (IS) environments

without an engineering review of the air quality including the presence of other constituent

gasses and dusts. Contact ADC for application assistance if necessary.

Warning: The DRU is powered by 48 VDC power which is supplied over customer-provided

wiring. To prevent electrical shock when installing or modifying the DRU power wiring,

disconnect the wiring at the power source before working with uninsulated wires or terminals.

Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser

radiation 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 adapters of any digital unit or exposure to laser

radiation may result. An optical power meter should be used to verify active fibers. A

protective cap or hood MUST be immediately placed over any radiating adapter or optical

fiber connector to avoid the potential of dangerous amounts of radiation exposure. This

practice also prevents dirt particles from entering the adapter or connector

Danger: Do not look into the ends of any optical fiber. Exposure to laser radiation may result. Do

not assume laser power is turned-off or the fiber is disconnected at the other end.

Danger: Always allow sufficient fiber length to permit routing without severe bends. Fibers may

be permanently damaged if bent/curved to a radius of less than 2 inches (50 mm).
