3.2.3 Cooling Requirements
The TWTA is provided with a number of cooling fans. It is important that air movement around the rear of
the unit be unobstructed.
CAUTION:
Do not position the TWTA in such a way that the air intakes or outlets are
blocked, or that the exhaust air flow is directed into air intakes. See
Section 3.5 for location of air intakes and air outlets. Make sure that the
intake air is 45°C or below. Great care must be taken to minimize any
exhaust air restrictions. Avoid mounting heat-producing equipment near
the TWTA, especially below the TWTA’s air intakes. Pay special
attention to the location of RF loads and lossy coaxial cable connected
directly to the TWTA which may conduct heat back to the TWTA. Use
supplemental fans as necessary to cool these components, directing this
heat away from the rear of the TWTA. Failure to provide adequate
cooling can result in the unit shutting down from overtemperature
conditions. The TWTA dissipates approximately 1.5-2.5 kilowatts when in
the Operate mode.
3.2.4 AC Line Power Connections
AC line power connection to the Power Supply Chassis is made at the AC inlet J1, which is a male, 4 pin
receptacle, MS3102A22-22P. The power connector pinout is as follows.
AC IN Pinout
A AC
B Neutral
C Safety Ground
D NC
WARNING:
Improper grounding of this equipment can result in electric shock. The
TWTA must be operated only with a line cord with a safety ground wire.
It is the user's responsibility to ascertain that the power connector is
properly wired and that the power outlet is grounded.
CAUTION:
Main supply voltage fluctuation not to exceed the nominal voltage range
of 190-260 VAC.
