Moseley SL9003Q 602-12016 Revision G
3.3.1. Facility Requirements
The site selected to house the SL9003Q should follow conventional microwave practice
and should be located as close to the antenna as possible. This will reduce the RF
transmission line losses, minimize possible bending and kinking of the line, and allow for
the full range potential of the radio link.
The building or room chosen for installation should be free from excessive dust and
moisture. The area should not exceed the recommended temperature range, allow for
ample air flow, and provide room for service access to cables and wiring.
3.3.2. Power Requirements
The AC power supply uses a universal input switching supply that is adaptable to power
sources found worldwide. The line cord is IEC (USA) compatible, and the user may
need to adapt to the proper physical AC connector in use.
For DC input units, double-check the input voltage marking on the rear panel does
indeed match the voltage range provided by the facility. Verify that the power system
used at the installation site provides a proper earth ground. The DC option for the
SL9003Q have isolated inputs by default, but the user may hard-wire a negative chassis
ground inside the module, if desired.
An uninterruptible power supply backup (UPS) system is recommended for remote
locations that may have unreliable source power. Lightning protection devices are highly
recommended for the power sources and antenna feeds.
3.3.3. Rack Mount Installation
The SL9003Q is designed for mounting in standard 19” rack cabinets, using the rack ear
brackets included with the SL9003Q. The rack ear kit is designed to allow flush mount
or telecom-mount (front extended). See Figure 3-6 for bracket installation. Be sure to
provide adequate air space near the ventilation holes of the chassis (top, bottom, and
sides).
