Electrocution Hazard / Risque D'électrocution - Redline RDL-3000 SC User Manual

RDL-3000 FAMILY
The system must be properly grounded to protect against power surges and
accumulated static electricity. It is the user's responsibility to install this device in
accordance with the local electrical codes: correct installation procedures for grounding
the unit, mast, lead-in wire and discharge unit, location of discharge unit, size of
grounding conductors and connection requirements for grounding electrodes.
All outdoor wireless equipment is susceptible to surge damage from a direct hit or
current induced from a near strike. A direct lightning strike may cause serious damage
even if recommended guidelines are followed. Installing surge protection and following
grounding practices detailed in local and national electrical codes can minimize
equipment damage, service outages, and chance of serious injury.
The major reasons for surge damage can be summarized as:
- Poorly grounded antenna sites
- Improperly installed surge protection equipment
A lighting protection system provides a means by which the energy may enter earth
without passing through and causing damage to parts of a structure. A good grounding
system disperses most of the surge energy from a lightning strike away from the building
and equipment. Improperly grounded connections are a source of noise that can cause
malfunctions in sensitive equipment. The remaining energy on the Ethernet cable shield
and conductors can be directed safely to ground by installing a surge arrestor in series
with the cable. A surge protection system does not prevent lightning strikes, but protects
equipment by providing a low resistance path for the discharge of energy safely to
ground. If you have determined that surge protection is required for your system, the
following general industry practices are provided as a guideline only:
The AC wall outlet ground for the indoor POE adapter should be connected to the
1.
building grounding system.
Install a surge arrestor in series with the Ethernet cable at the point of entry to the
2.
building. The grounding wire should be connected to the same termination point
used for the tower or mast.
Provide direct grounding connections from the RDL-3000, the mounting bracket, and
3.
the antenna to the common building ground bus. Use the grounding screws provided
for terminating the ground wires.
L'installation exige aussi que l'appareil soit branché à un parafoudre qui répond à
toutes les normes nationales de sécurité.
Electrocution Hazard / Risque D'électrocution
Warning to Service Personnel: 48 VDC
This product is intended to be connected to a –36 to -57 VDC power source, which
must be electrically isolated from any ac sources and reliably connected to Earth
ground. Do not install Redline products near any type of power line. Should your
antenna or related hardware come in contact with power lines, severe bodily harm or
death could result!
Attention au personnel du service: 48V CD
Cet appareil est raccordée à une source de tension de –36 a -57 VCD, qui doit être
isolée de toute autre source de tension et raccordée à une mise à terre isolée. Les
produits de Redline ne doivent pas être installés près de ligne à haute tension. Des
dommages corporels sévères et même la mort peuvent survenir si l'antenne ou toute
autre pièce viennent en contact avec des lignes de haute tension Dommage corporel.
