Fortress Wireless Access Bridge: Installation
10
PoE powered from a remote 802.11af (13 Watt) PoE
midspan source.
‹ Circuit Overloading: The Bridge includes a 48 V main
resettable fuse specified at 1.8 A.
‹ Lightning/Electrostatic Protection: The Bridge’s antenna
ports conform to IEC1000-4-5 10 KV 8/20us waveform. The
WAN port conforms to IEC-61000-4-2 8 KV waveform with
58 V additional transient protection.
‹ Grounding: The Bridge features a rear panel grounding
stud which, on Bridges with externally mounted antennas,
must be connected to protective earth ground via a 20
gauge (minimum) cable, before any other physical
connection is made.
The antenna/cable distribution system should be grounded
(earthed) in accordance with ANSI/NFPA 70, the National
Electrical Code (NEC), in particular, Section 820.93,
Grounding of Outer Conductive Shield of a Coaxial Cable.
The antenna mast and Secure Wireless Access Bridge,
when used outside, should be grounding per Article 810 of
the NEC; of particular note is the requirement that the
grounding conductor not be less than 10 AWG(Cu).
‹ Cabling: Cables must be installed in accordance with NEC
Article 725 and 800, and all requirements must be met in
relationship to clearances with power lines and lighting
conductors. All cabling must be category 5e per TIA/EIA-
568-B.2.
WARNING: If the
Bridge connects to
outside-mounted anten-
nas, failure to provide a
low resistive earth
ground can result in mi-
gration of voltage from
lightning or line surges
onto the premises wir-
ing, which can cause
electric shock and/or
fire within the building
or structure.
‹ Waterproofing: The Bridge has a UL (NEMA) 3/3S/4 raintight
rating. The Front-panel Cover Plate of the ES520
Weatherizing Kit includes a “Raintight” label. The Bridge is
water resistant when the Weatherizing Kit (cover plate,
WAN-port RJ-45 connector boot assembly, and antenna
cap—included) is properly installed.
‹ Radio Frequency: The Bridge’s internal radios conform to
the FCC’s safety standard for human exposure to RF
electromagnetic energy, provided that you follow these
guidelines:
™ Do not touch or move the antennas while the unit is
transmitting or receiving.
™ To safeguard Bridge transmitting circuitry, relocate the
Bridge and its antennas only when the Bridge is
powered off.
™ When the Bridge is transmitting, do not hold it so that
the antenna is very close to or touching any exposed
parts of the body, especially the face or eyes.
