Before starting the repair work, please note the following safety instructions:
Warning!
Danger to life.
• De-energise the instrument before you open it. Check that there is no voltage and
secure the switch(es) against switch-on.
• If work is required under voltage, this may only be carried out by an electrician, but a
second person must be present for safety reasons.
• Switch contacts may be powered by separate circuits. Also de-energise these circuits
before you work on the terminals.
Caution!
Danger to components through electrostatic discharge (ESD).
• Electronic components are sensitive to electrostatic discharge. Take protective
measures, e.g. remove the charge from your person by touching the PE or wear a
permanent grounding in the form of a wrist strap.
Highly dangerous: Plastic floors at low air humidity and clothing made of synthetic
materials.
• For your own safety, always use genuine spare parts. Only genuine spare parts
ensure the correct function, precision and reliability after repairs.
