Risk of Personal Injury from Electrical Shock
DANGER – HIGH CURRENT HAZARD: Do not turn on
power before reading the Triton Network Systems’ product
documentation. This device has a – 48 Vdc (5.0 amps operating
peak per feed) direct current input.
DANGER – HIGH CURRENT HAZARD: Ensure that the
– 48 Vdc power source is set to the OFF position before
beginning the installation procedures for the Invisible Fiber™
unit.
DANGER – HIGH VOLTAGE HAZARD: Do not work on
the system or connect or disconnect cables during periods of
lightning activity, rainy weather, or both.
WARNING: Instructions for installing cables are intended for
licensed contractors or building maintenance personnel.
Risk of Personal Injury from Fiber Optics
DANGER: Invisible laser radiation. Avoid direct eye exposure
to the end of a fiber, fiber cord, or fiber pigtail. The infrared
light used in fiber optics systems is invisible, but can cause
serious injury to the eye.
WARNING: Never touch exposed fiber with any part of your
body. Fiber fragments can enter the skin and are difficult to
detect and remove.
Risk of Personal Injury from Radio Frequency
Energy Exposure
WARNING: Beware! Radio transmitter is ON when the red
light indicator on the back side of the Invisible Fiber™ unit is
illuminated. Observe all radio frequency energy exposure and
service interruption cautions.

Warnings and Safety Guidelines xvii
WARNING – RADIO FREQUENCY ENERGY: To comply
with FCC and Health Canada RF exposure requirements, a
minimum separation distance of 40 feet in front of the Invisible
FiberTM unit is required between this antenna and all persons
while the transmitter is ON. The radio transmitter is ON when
the red light indicator on the back side of the radio enclosure is
illuminated. Observe RF energy exposure safety limits,
applicable rules, and service interruption cautions in the product
manuals. Serious bodily injury may result.
Other Risks of Personal Injury
NOTE: The following warnings and cautions are for risk of injury
from sources other than electrical shock, fiber optics, or radio
frequency energy exposure.
WARNING: This Invisible Fiber™ unit is designed to permit
the connection of the earthed conductor from the DC source
circuit to the earthing conductor at the Invisible Fiber™ unit. Do
not switch or disconnect devices in the earthed circuit conductor
between the DC source and point of connection of the earthing
electrode conductor.
WARNING: Failure to follow operating instructions could
result in death or serious injury.
CAUTION: Instructions for installing cables are intended for
licensed contractors or building maintenance personnel.
CAUTION – LIFTING HAZARD: Two people are required
to lift the Invisible Fiber™ unit. Grasp the Invisible Fiber™ unit
underneath the lower edge and lift with both hands. To prevent
injury, keep your back straight and lift with your legs, not your
back. To prevent damage to the Invisible Fiber™ unit and
components, never attempt to lift the radio by the attached
cables.
CAUTION: Keep tools and parts away from walkways. When
carrying large, heavy equipment (such as the Invisible Fiber™
unit), obstacles (such as hand tools, cables or components) may
not be easily visible and can cause accidents.

Risk of Service Interruption
CAUTION: Handle the Invisible Fiber™ unit with care to
avoid equipment damage.
CAUTION: Ensure the outside optical fiber connectors are
environmentally protected. Failure to do so may cause
contamination of the fiber surfaces.
CAUTION: The Invisible Fiber™ unit contains no owner or
user serviceable parts. Opening the radio unit or tampering with
any of its seals voids all warranties.
CAUTION: Prior to installing an Invisible Fiber™ unit, the
installation site must be surveyed to assess its appropriateness or
adequacy, system requirements, path analysis, signal path, and
power requirements.
CAUTION: Instructions for installing cables are intended for
licensed contractors or building maintenance personnel.
CAUTION: DO NOT lift the Invisible Fiber™ unit by the
radome (front) cover to avoid damaging the antenna.
CAUTION: Ensure the mounting bracket and Invisible Fiber™
unit are installed properly according to the instructions in the
Triton Network Systems’ product documentation.
CAUTION: Ensure that the – 48 Vdc power source is set to the
OFF position before attaching power cables to the Invisible
Fiber™ unit.
CAUTION: Do not block the front of the Invisible Fiber™ unit
to avoid possible radio service interruption.
CAUTION: To reduce the risk of fiber optic cable damage, use
the following bend radius guidelines for indoor/outdoor fiber
optic cable:
Long-term (installed): bend radius is equal to 10 times the
diameter of the cable.
Short-term (during installation): bend radius is equal to 20
times the diameter of the cable.

Warnings and Safety Guidelines xix
Other Precautions
Failure to follow the installation procedure described in the Triton Network
Systems’ product documentation may result in damage to the Invisible
Fiber™ unit and render the unit unusable. If you have any questions, contact

The Invisible Fiber™ unit must be installed in accordance with wall-mount or
pole-mount specifications described in the Triton Network Systems’ product
documentation.
Observe all federal and local laws, regulations, electrical codes, building
codes, fire codes, and licensing agreements.
RF Energy Exposure Safety Limits and Applicable Rules
The radio is tested for RF radiation level exposures (per FCC OET-65 and
FCC 47 CFR 1.1310 requirements) to transmit at below the FCC 47 CFR
1.1310 and Health Canada Safety Code radio frequency maximum
permissible exposure limits (MPE) for controlled/occupational environment
and below the FCC 47 CFR 1.1307 environmental radiation limit, when
installed, operated, and maintained in strict accordance with the product
operating and installation manuals and other materials accompanying the
devices, at any time and under all operating conditions.
Ensure that appropriate warning signs are properly placed and posted at the
equipment site or access entry.
WARNING: Changes or modifications to this unit not expressly approved by
the party responsible for compliance could void the user’s authority to operate
the equipment.
