2.2.7 Proper Grounding
When the receiver is installed, make sure that the antenna and coaxial cable is properly
grounded to avoid static build up and voltage spikes that can occur due to lightning and other
types of power surges. Proper earth grounding of the rack system should be maintained and
particular attention should be paid to connections that go through power strips.
Warning! Make sure all power strips are properly grounded.
2.2.8 Circuit Overloading
The StarGuide III receiver can draw up to 1.5 Amps at 120VAC as labeled on the back of the
receiver. Care should be exercised when installing the receiver into an existing rack so that the
maximum current rating of the circuit is not exceeded. Do not exceed over-current protection
and supply wiring specifications.
2.2.9 Foreign Objects
Warning! Do not insert any type of object, including fingers, into
the ventilation holes of the receiver. Doing so could
result in shock and serious injury to the operator.
If a foreign object is accidentally introduced into the receiver, immediately remove power and
call StarGuide Digital Networks technical support. Do not try to open the receiver since there
are no serviceable parts in the receiver. Opening the receiver will void the receiver’s warranty.
2.3 Physically Installing the StarGuide III Receiver
The StarGuide III receiver should be installed in a standard 19-inch rack. The following
sections provide information on the physical installation of the receiver.
2.3.1 Rack Mounting the Receiver
The StarGuide III receiver has been designed to fit into a standard 19-inch rack. Four screw
holes are provided on the front panel to directly mount the receiver in the rack. Be sure to
install all four screws when mounting the receiver. See Figure 1. Rack Mounting the
StarGuide III Receiver.
Caution! Do not paint mounting ears as they provide a grounding
path to the rack.
2.3.2 Uneven Loading of Rack
When installing the StarGuide III receiver into a rack, ensure that the rack is loaded with
heavier pieces of equipment at the bottom and lighter pieces at the top.
Caution! Uneven loading can cause hazardous conditions and
may result in rack instability.
