General Safety Information
The following general safety precautions must be observed during all phases of 
operation, service, and repair of this instrument. Failure to comply with these 
precautions or with specific warnings elsewhere in this manual violates safety 
standards of design, manufacture, and intended use of the instrument. Aligent 
Technologies assumes no liability for the customer’s failure to comply with

General
This is a Safety Class I instrument (provided with terminal for protective 
earthing) and has been manufactured and tested according to international 
safety standards.
This instrument is designed and certified as a general purpose laboratory 
instrument for research and routine application only. It is not certified for 
in-vitro or medical applications.
Operation
Before applying power, comply with the installation section. Additionally the 
following must be observed.
Do not remove instrument covers when operating. Before the instrument is 
switched on, all protective earth terminals, extension cords, 
auto-transformers, and devices connected to it must be connected to a 
protective earth via a ground socket. Any interruption of the protective earth 
grounding will cause a potential shock hazard that could result in serious 
personal injury. Whenever it is likely that the protection has been impaired, 
the instrument must be made inoperative and be secured against any intended 
operation.
Make sure that only fuses with the required rated current and of the specified 
type (normal blow, time delay, and so on) are used for replacement. The use of 
repaired fuses and the short-circuiting of fuseholders must be avoided.
