Chapter 1 Pre-Installation Considerations
Proper installation ensures the best possible performance and reliability of the MOTOTRBO
Repeater. Pre-installation planning is required. This includes considering the mounting location of
the repeater in relation to input power and antennas. Also to be considered are site environment
conditions, the particular mounting method (several available), and required tools and equipment.
If this is the first time installing this type of equipment, it is highly recommended that the user read:
• this entire installation section before beginning the actual installation, and
• the Motorola Quality Standard Fixed Network Equipment Installation manual, R56
(6881089E50), specifically refer to the information on ground connection for lightning
protection.
1.1 Installation Overview
The following information is an overview for installing the MOTOTRBO Repeater and ancillary
equipment. Step-by-step procedures for each of the major installation tasks are then provided
beginning in Section 2, Mechanical Installation.
• Plan the installation, paying particular attention to environmental condition at the site, ventilation
requirements, and grounding and lightning protection.
• Unpack and inspect the equipment.
• Mechanical install the equipment at the site.
• Make necessary electrical and cabling connections, including the following:
- AC input cabling
- Caoxial cables to transmit and receive antennas
• Perform a post-installation function checkout test of the equipment to verify proper installation.
• Proceed to the Optimization procedures to customize the repeater parameters per customer
specifications (e.g. operating frequency, PL, codes, color code, etc.).
1.2 Environmental Conditions at Intended Installation Site
The repeater may be installed in any location suitable for electronic communications equipment,
provided that the environmental condition do not exceed the equipment specifications for
temperature, humidity, and air quality.
1.2.1 Operating Temperature Range
-30°C (-22°F) to +60°C (+140°F)
This is the temperature measured in close proximity to the repeater. For example, if the repeater is
mounted in a cabinet, the temperature within the cabinet is measured.
If the repeater is to be installed in an environment which is usually dusty or
dirty (and so does not meet the air quality requirements), the air used to cool
the repeater modules must be treated using appropriate filtering devices. Dust
or dirt accumulating on the internal circuit boards and modules is not easily
removed, and can cause such malfunctions as overheating and intermittent
electrical connections.
