ES520 Hardware Guide: Installation

FOR ES520 VERSION 2: The Mesh Point can be 1) direct
powered by the universal AC-to-48V DC (70 Watt) power
adapter, 2) PoE powered over the WAN port with the
included POE midspan adapter (or equivalent), 3) PoE
powered from an 802.11af PSE, or 4) externally powered
from a 7-30V (12/24) power source. Do not exceed 30V on
the 7-30V (12/24) power input or the unit can be damaged.
The AC to 48V power adapter included with both hardware
versions has reinforced isolation to meet the endspan
requirements of 802.11af, Power Sourcing Equipment.
 Lightning/Electrostatic Protection: The Mesh Point’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.
WARNING: If the
Mesh Point con-
nects to outside-mount-
ed antennas, failure to
provide a low resistive
earth ground can result
in migration of voltage
from lightning or line
surges onto the premis-
es wiring, which can
cause electric shock
and/or fire within the
building or structure.
 Grounding: The Mesh Point features a rear panel
grounding stud which 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 Deployable Mesh Point, 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).
 Waterproofing: The Mesh Point has a UL (NEMA) 3/3S/4
raintight rating. The Front-panel Cover Plate of the ES520
Weatherizing Kit includes a “Raintight” label. The Mesh
Point is water resistant when the Weatherizing Kit (cover
plate, WAN-port RJ-45 connector boot assembly, and
antenna cap—included) is properly installed.
 Cabling: Cables must be installed in accordance with NEC
Article 725 and 800, and all requirements must be met in
relation to clearances with power lines and lighting
conductors. All cabling must be category 5e per TIA/EIA-
568-B.2.
 Radio Frequency: The Mesh Point’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 Mesh Point transmitting circuitry, relocate
the Mesh Point and its antennas only when the Mesh
Point is powered off.
 When the Mesh Point 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.
