Typical Tightening Pattern
Air Ducting
The location of the air inlet and exhaust ports were shown in Figure 2-1. A minimum clearance of
two inches is required for the air inlets and exhaust ports. If the amplifier is mounted in an enclosed
chamber, duct the exhaust air to the outside of the chamber. Do not recirculate the exhaust air back
into the amplifier. Use an exhaust duct that is not smaller than the exhaust port of the amplifier and
one that has smooth bends and transitions.
Prime Power Connections
The location of the prime power input connector is shown in Figure 2-4.
WHEN THE CONTROLLER IS DISCONNECTED OR SET TO AC OFF,
PRIME POWER IS STILL PRESENT IN THE INTERIOR OF THE TWTA.
DISCONNECT PRIME POWER BEFORE SERVICING THE UNIT.
