AWSA-K50-CHE
---------------------------------------------- WARNING -----------------------------------------------------
When supplying power to this equipment, connect the accessory 3-pin power connector (with
extension cable) to a 3-pin grounded power outlet. If power is supplied without grounding the
equipment, there is a risk of receiving a severe or fatal electric shock.
In the context of this document any voltage that is lethal is viewed as 'High Voltage'. Therefore,
even prime power (90 to 265 VAC) is dangerous because prime power potentials have been
known to cause death or injury.
----------------------------------------------- WARNING ----------------------------------------------------
This equipment can not be repaired by the operator. DO NOT attempt to remove the
equipment cover or to disassemble internal components. Only qualified service technicians
should service this equipment. There are high-voltage parts in this equipment presenting a risk of
severe injury to untrained personnel. In addition, there is a risk of damage to precision
components.
----------------------------------------------- WARNING ----------------------------------------------------
ALWAYS TERMINATE THE OUTPUT WAVEGUIDE OF THE POWER AMPLIFIER
WITH AN RF LOAD CAPABLE OF DISSIPATING FULL CW RF POWER. Incorporate
the termination prior to applying prime power to the power amplifier. This procedure prevents
self oscillation and irradiation of the local environment. Even if a source is not connected to the
power amplifier you are working with, there are situations where the power amplifier can go into
a self induced mode and generate high levels of RF energy. Destruction caused under excessive
load voltage standing wave ratio (VSWR) will void the warranty. Although the equipment has
internal protection for VSWR higher than 3:1 and will automatically go in shutdown (with a
delay of 1 second), still it is a safe procedure to avoid unwanted effects.
----------------------------------------------- WARNING ----------------------------------------------------
DO NOT LOOK INTO THE RF OUTPUT PORT OF THE POWERED POWER
AMPLIFIER. Treat the powered amplifier with extreme care. Your eyes are particularly
vulnerable parts of your body.
