2. Safety
WARNING!
■ Observe the working conditions in accordance with chapter
3 "Specifications".
■ Prior to opening the instrument, disconnect it from the power
supply. Take care that, in fitting the instrument and connec-
tions, all components are protected against direct contact.
■ Observe standard regulations and safety rules for electrical,
low-power and high-power systems, especially any country-
specific safety regulations (for example VDE 0100).
■ Design the wiring particularly carefully when connecting
to other devices (e.g. a PC). Under certain circumstances,
internal connections in third-party devices (e.g. GND
connected to the safety earth) can lead to impermissible
voltages.
■ If the connected cable is longer than 30 metres, or it runs
outside the building, an additional and suitable overvoltage
protection should be provided.
The safety of the operator may be endangered if, for example:
■ there is visible damage to the instrument.
■ the instrument is not working as specified.
■ the instrument has been stored under unsuitable conditions for an
extended period of time.
If there is any doubt, please return the instrument to the manufacturer for
repair or maintenance.
