NOTICE
Risk of device damage by wrong voltage.
• Make sure that the voltage on the socket corresponds to the voltage given on the type plate
of the instrument.
• Always connect the device to an earthed socket. External connections and extension cables
must be provided with an earthed conductor lead (3-pole couplings, cable or plug equipment)
as the mains lead has a molded plug, thus avoiding risks due to inadvertent defective wiring.
• Make sure that no electric sparks form in the device or its surroundings as they might
damage the instrument.
