60 WLAN 2300 Series Outdoor Solution with AP Mounted in NEMA Enclosure
• If anything, such as a wire or mast, does come in contact with a powerline, DO NOT TOUCH IT OR
ATTEMPT TO MOVE IT. Call the power company.
• Do not attempt to errect antennas or towers on windy days.

Installation

• The horizontal distance from a tower, mast or antenna to the nearest power line should be at least twice the
total length of the mast/antenna combination. This will ensure that the mast will not contact the power line if
it falls either during installation or later.
• Make sure that all towers and masts are securely grounded and electric cables connected to antennas have
lightning protection. This will help to prevent fire damage or human injury in case of lightning, static
build-up, or short circuit when equipment is connected to the antenna.

Heat /Cold loading

The NEMA Enclosure environment must not exceed the operating specifications for the AP (2330 A or
2330B). Temperature must be between 0 to 50 degrees C and humidity between 10 to 95%, non condensing.

Ethernet and Antenna Lightning Surge Protector

The Nortel series gas-discharge Antenna surge Protector (lightning protector) provides high-level protection
for transmitters and receivers at RF-communication sites. In the event of a local strike, the unit's gas discharge
tube ionizes instananeously to limit sudden voltage surges across the coaxial line. When connected to a
satisfactory ground, the unit can safely shunt up to 5000 Amps of impulse current away from sensitive station
equipment.
Warning!
A rated surge Protector is required for any cable/antenna combination exiting the
building. The required components must be rated and approved for use in the intended
application.
Installation
The Ethernet Lightning Surge Protector is mounted close to the building entrance. The cables must enter the
building through customer provided access, possibly through the drilled hole where there are communications
pipes.
For better results, install the Lightning Surge Protector in close proximity to a low-resistance ground at a point
where the Ethernet cable enters the building. In most cases, one 8-foot rod driven into moist soil or multiple
rods bonded together will provide adequate grounding.
Install the Lightning Surge Protector in an accessible location that allows for periodic inspection. Provide drip
loops in the cables to prevent water from entering the building.
