NOTE
To cut the power in case of an emergency by unplugging, the instruments or any other items
must not block the mains plug! External connections and extension lines must be provided with a
grounded conductor lead (3-pole couplings, cord or plug equipment). All used power cords must
meet the input power requirements.
Demands on the mains circuit
The mains circuit must
• provide the voltage that is given on the type plate of the instrument.
• be able to handle the load of the connected instrument(s).
• be equipped with adequat fusage and electrical safety measures, in particular proper grounding.
NOTE
Additional electrical safety measures such as residual current breakers may be necessary to meet
local laws and regulation!
External power switches (e.g. emergency stop switches) must meet IEC 60947-1 and IEC 60947-3
requirements. Such devices must be clearly labeled and accessible at any tim.
