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. The TWTA dissipates approximately 600 watts when it is in the Operate mode.
CAUTION:
For either bench-top 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 air flow restrictions. Avoid mounting heat-producing
equipment in the same rack, especially below the TWTA. Failure to
provide adequate cooling can result in the unit’s shutting down from over-
temperature conditions.
3.2.4 AC Line Power Connection
AC line power connection to the TWTA is made at the AC inlet J1, which is a female IEC-320 connector. 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 for the line cord is 18 gauge.
