10. Safety notes
● Before you start the device check for which power supply
it is built.
● Verify that the connection leads are in good condition and
that they are electrically dead while wiring the device.
● When it must be assumed that safe operation is no longer
possible, take the device out of service (eventually
disconnect the power supply and the input voltage!).
This can be assumed on principle when the device shows
obvious signs of damage.
The device must only be used again after troubleshooting,
repair and a final test of calibration and dielectric strength
in our factory or by one of our service facilities.
● When opening the cover, live parts may be exposed.
Calibration, maintenance or repair with the device
open and live must only be performed by a qualified
person who understands the danger involved.
Capacitors in the device may still be charged even
though the device has been disconnected from all
voltage sources.
