High Voltage
High voltages in excess of 6 kV are present within the amplifier. However, the
equipment is designed so that personnel cannot come into contact with high voltage
circuits unless the covers are removed.
RF Radiation
Exposure of the human body to microwave radiation can constitute a hazard (ANSI/
IEEE C95-1-1992). Personnel must be protected from microwave energy produced by
the TWT.
All RF connectors must be correctly fitted before operation, so that there is no
leakage of RF energy. The amplifier must not be operated unless the RF output
connection is correctly terminated. It is particularly hazardous to look into open
waveguides, coaxial feeders, or transmitter antennae when the amplifier is operating.
Input Drive
Damage to the amplifier may occur if the RF input drive level or the input frequency
are outside the limits given in the specification (section 8, also summarised in section
3.2).
Environmental
*
Do not block, or poke objects through, the amplifier ventilation slots.
*
Do not spray aerosol cleaners directly on to the amplifier surfaces when
cleaning.
*
Do not operate the amplifier on an unstable or unsafe surface.
*
Ensure that all cables cannot be walked on, tripped over or damaged by
furniture or movable equipment.
*
Do not place objects inside the waveguide.
STANDARDS COMPLIANCE
Stellar amplifiers comply with the following requirements. Further details may be
provided if necessary.
*
EEC Directive 89/336/EEC Electromagnetic compatibility.
*
EEC Directive 93/97/EEC Satellite earth station equipment.
*
