3.2.3 Cooling Requirements
The TWTA is provided with a cooling fan. It is important that air movement around the rear of the unit be
unobstructed.
CAUTION:
For either bench or rack mounting, do not position the TWTA in such a
way that the air intake or outlet are blocked, or that the exhaust flow is
directed into the intake. See Paragraph 3.5 for location of air intake and
air outlet. If the unit is rack mounted, make sure that the intake air is
45°C or below. If necessary, fabricate a short duct to direct the hot
exhaust air out of the rack enclosure. Great care must be taken to
minimize any exhaust air restrictions. Avoid mounting heat-producing
equipment in the same rack, especially below the TWTA. Failure to
provide adequate cooling can result in the unit shutting down from
overtemperature conditions.
The TWTA dissipates approximately 1.5 kilowatts when in the operate mode.
3.2.4 AC Line Power Connections
AC line power connection to the TWTA is made at the AC inlet J1, which is a female IEC-320 16A
connector. The connector is provided with a bracket that can be used to secure the plug from accidental
withdrawal. A line cord suitable for the type of AC outlet used, and consistent with local electrical codes,
must be obtained to mate with J1. Minimum wire size recommended for the line cord is 1.5 mm² (16 AWG).
Units are provided with an unterminated 3-wire cord. To use this line cord it should be terminated with a
suitable plug to a 190 to 260 VAC 50-60 Hz. single-phase source as follows:
