Chapter 4 Maintenance
4.1 INTRODUCTION
The E&I 100S1 RF amplifier requires no periodic maintenance. The instrument is
unconditionally stable and is fail-safe under all load conditions. Damage can only
be externally caused by overdrive in excess of 2 watts (+33 dBm) or back-feeding
the output of the unit from another high power source or incorrect connection to
the AC input.
4.2 PACKAGING FOR RESHIPMENT
In the event of the equipment being returned for servicing it should be packed in
the original shipping carton and packing material. If this is not available, wrap the
instrument in heavy paper or plastic and place in a rigid outer box of wood,
fiberboard or very strong corrugated cardboard. Use ample soft packing to prevent
movement. Provide additional support for projecting parts to relieve these of
unnecessary shock. Close the carton securely and seal with durable tape. Mark
the shipping container FRAGILE to ensure careful handling.
Chapter 5 Safety:
Do not attempt to operate this unit with the cover removed. High voltages are
present. The cover protects against electrical shock due to hazardous supply
voltages, high DC, RF voltages and RF fields. Further the cover provides part of
the cooling system design. Components will over heat and cause eventual failure
if the unit is operated without the cover in place.
N.B. Removal of cover will void warranty.
Ensure that the load is connected to the output prior to connecting the RF input to
the unit. This will prevent high voltages being present and exposed at the output
connector.
Operation of AC voltage above 264 V could severely damage the unit and present
a hazard.
