Pre-Installation Considerations, Humidity

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 consider the site environmental conditions, the particular mounting method (several available), and required tools and equipment.

If this is the first time this type of equipment is being installed, 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.

1.1Installation Overview

The following information is an overview for installing the MOTOTRBO Repeater and ancillary equipment.

•Plan the installation, paying particular attention to environmental conditions 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

-Coaxial cables to transmit and receive antennas

•Perform a post-installation function checkout test of the equipment to verify proper installation.

•Proceed to customize the repeater parameters per customer specifications (e.g. operating frequency, PL, codes, color code, etc.).

1.2Environmental Conditions at Intended Installation Site

The repeater may be installed in any location suitable for electronic communications equipment, provided that the environmental conditions do not exceed the equipment specifications for temperature, humidity, and air quality.

NOTE: Since mid 2008, the XPR 8300 Repeater has been manufactured with a power-saving main fan. The fan powers ON temporarily as a self-check after user initially turns the repeater power ON. If the repeater’s internal ambient temperature remains below 30°C (86°F), the fan does not operate. It powers ON and remains operational only after the repeater’s internal ambient temperature rises above 30°C (86°F), and its speed increases as the temperatures rises. At 50°C (122°F), the fan runs at full speed.

1.2.1Operating 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.

1.2.2Humidity

Humidity conditions should not exceed 95% relative humidity @ 50°C (122°F).
