SAFETY NOTES
The following warnings and precautions are for your safety and the prevention of
injury. Please read them carefully and observe at all times when installing or operating
a Stellar Travelling Wave Tube Amplifier. Hazard warning signs, as defined in BS5378
Safety Signs and Colours, are used on the equipment to highlight any possible
hazards.
Earthing
A protective earth must be connected to the amplifier before applying the mains
supply. This protective earth must only be removed after disconnecting the amplifier
from the mains supply. The protective earth must be connected to the local system
earth point, must be capable of carrying 30 A and must conform to the regulations in
the British Standard Codes of Practice
BS7430 (1991 Earthing), or equivalent
national regulations.
Mains Supply
A mains supply disconnection device must be provided to isolate this amplifier from
the mains supply source. Either a socket outlet or a two pole isolation switch must be
used as the mains supply disconnection device, and it must be easily accessible. The
mains connector must not be used as the mains supply disconnection device.
Toxic Material
The Travelling Wave Tube (TWT) within the amplifier contains beryllium oxide. Dust
created by breakage, or fumes from a beryllium oxide fire, are highly toxic if inhaled,
or if particles enter the body via a cut or abrasion.
Consult e2v technologies and the appropriate national authorities for details
regarding the disposal of damaged or old TWTs and amplifiers.
