2.2.2 Proper Ventilation
Air vents located on the sides and rear of the StarGuide receiver are provided for proper
ventilation. In order to ensure proper operation the StarGuide receiver should be located such
that it’s ventilation is not impeded. In a rack environment, at least two inches on the sides and at
least 5 inches in the rear should be provided. Proper ventilation will help ensure that the
receiver performs both safely and reliably.
2.2.3 Heat, Humidity, and Dust
In order to avoid unnecessary internal damage, do not place the receiver next to heat sources
such as heaters, direct sunlight, heating ducts, etc. Also avoid locations that have high humidity,
dust and vibration.
2.2.4 Card Options
When installing option cards on the StarGuide III receiver, make sure power is off and the cards
are fully seated and secured with mounting screws. Unused card slots must have the filler plates
installed to maintain emissions integrity and proper cooling of the receiver. Refer to Appendix
A for further details on installing the option cards
Port shields (SGN P/N 61000-6006) must be reinstalled in order to maintain emissions integrity
of the receiver chassis.
A Card Extractor Tool (SGN P/N 28882-3005) may be required to assist option card removal.
See Appendix A for further details.
2.2.5 Use the Correct Power Source
For StarGuide III units equipped with a North American power cord, the power cord has an IEC
320 female plug at one end, and a NEMA 5-15P male plug on the other end. This cord is UL
and CSA approved up to 125 VAC at 10A and is ready to use with no user wiring required.
For StarGuide III units equipped with an International power cord, the cord has an IEC320
female plug on one end, and three stripped and tinned bare wires on the other end. This cord is
HAR approved, up to 250 VAC at 6A, and complies with the international color codes of
green/yellow (ground), blue (neutral), and brown (line).
If these color codes do not correspond to the colored markings on the terminals in the plug, use
the following standards:
•
The green/yellow wire must be connected to the plug terminal marked by the letter E, or
the earth symbol: or color-coded green and yellow.
•
The blue wire must be connected to the plug terminal marked with the letter N or color-
coded black.
•
The brown wire must be connected to the plug terminal marked with the letter L or
color-coded red.
