Site Preparation; Grounding Requirements - Motorola AP-7161 Installation Manual

10
• Do not hold any component containing a radio such that it is very close to or touching any exposed parts of the body,
especially the face or eyes, while transmitting.
• Do not work with power circuits in dimly lit spaces.
• Do not install this equipment or work with its power circuits during thunderstorms or other weather conditions that could
cause a power surge.
• Verify there is adequate ventilation around the device, and that ambient temperatures meet equipment operation
specifications.
• Avoid contact with overhead power lines.
• Take precautions to avoid injury from falling tools and equipment. Crews should wear hard hats in and around the installation
work site.
• Be aware of vehicular traffic in and around the installation work site.
• Do not operate a portable transmitter near unshielded blasting caps or in an environment where explosives are present
unless the transmitter is especially certified for such use.

Site Preparation

• Consult your site survey and network analysis reports to determine specific equipment placement, power drops, and so on.
• Assign installation responsibility to the appropriate personnel.
• Identify and document where all installed components are located.
• Identify and prepare Ethernet and console port connections.
• Verify that cable lengths are within the maximum allowable distances for optimal signal transmission.

Grounding Requirements

To avoid damage to the equipment, become familiar with Motorola Solutions Policy R56 before installing AP-7161 units. Refer
to Standards and Guidelines For Communication Sites, Version B. Both the hardcopy manual (Part Number 68P81089E50-B)
and the CD version (Part Number 9880384V83) can be ordered from Motorola Solutions.
Section 7.6.4 Broadband - Wireless Access Point Network from the Standards and Guidelines For Communication
Sites applies directly to AP-7161 deployments: SPD (Surge Protection Device) considerations for broadband shall include the
use of SPDs to protect pole-mounted access points and ground-based cabinet architecture. It is important to install proper SPD
applications on both ends of Ethernet, Power-Over Ethernet (POE), Giga-Ethernet (GigE) and AC cable runs. SPDs shall be
located within the node or cabinet, or as close to the entrance as possible, and properly installed into load centers, control
panels and utility power cabinets. While RF protection is a consideration, it shall only be required when antennas are connected
to the node with coaxial cables greater than 610 mm (2 ft.) in length.
Lightning protection should be used on all shielded CAT-5E Ethernet connections.
An outdoor rated Lightning Protection Unit (LPU) kit such as the Motorola Solutions PTP WB2978AA or the HyperLink
AL-CAT6HPJW Lightning Protector should be used.
NOTE
Lightning damage is not covered under the conditions of a standard Motorola Solutions product
warranty. When installed correctly, LPUs provide the best protection from the harmful effects of
lightning. Observe all regional and national codes that apply for lightning protection.
