Disconnect the power to this product and return it for service if the following conditions
apply:
a. The terminal does not function after following the operating instructions outlined
in this manual.
b. Liquid has been spilled, a foreign object is inside, or the terminal has been
exposed to rain.
c. The product has been dropped or the housing is damaged.
Locate the serial number of the terminal, antenna, and transceiver and record these on your
registration card for future reference. Use the space below to affix serial number stickers.
Also record the MAC address, located on the back of the terminal.
UL Information
- The equipment must be properly grounded according with NEC and other local safety code
requirements.
- Reminder to all the BWA system installers: Attention to Section 820-40 of the NEC which
provides guidelines for proper grounding and, in particular, specifies that the cable ground shall
be connected to the grounding system of the building, as close to the point of cable entry as is
practical.
- AirSynergy is designed to operate in environmental conditions complying with IP66 and relevant
standards.
Lightning Protection
WARNING:
The following notes are general recommendations for the system. The wireless
equipment should be installed by a qualified professional installer and must follow local and
national codes for electrical grounding and safety. Failure to meet safety requirements and/or use
of non-standard practices and procedures could result in personal injury and damage to
equipment. A direct lightning strike may cause serious damage even if these guidelines are
followed.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit or induced
current from a near strike. Lightning protection and grounding practices in local and national
electrical codes serve to minimize equipment damage, service outages, and serious injury.
Reasons for lightning damage are summarized as:
- Poorly grounded tower/antenna sites that can conduct high lightning strike energy into
equipment.
- Lack of properly installed lightning protection equipment that can cause equipment failures from
lightning induced currents.
A lighting protection system provides a means by which the energy may enter earth without
passing through and damaging parts of a structure. A lightning protection system does not
prevent lightning from striking; it provides a means for controlling it and preventing damage by
providing a low resistance path for the discharge of energy to travel safely to ground. Improperly
grounded connections are also a source of noise that can cause sensitive equipment to
malfunction.
A good tower grounding system disperses most of the surge energy from a tower strike away
from the building and equipment.
To limit the equipment damage due to a lightning strike, the following practices are recommended
for the wireless system:
- Provide direct grounding from the antenna mounting bracket, the radio and antenna and the
lightning/surge protectors to the same ground point at the base of the tower or a ground bus on
the building. Use the grounding screws on the antenna bracket and the radio and antenna for
terminating the ground wires.
- The AC wall outlet ground must be connected to the same grounding system as the eNodeB.
