WARNING
The device is energized.
Danger! Risk of electric shock!
►
Before performing any cleaning work on the device, the device must be de-energized. Live
transformer cables must never be opened to remove any dust or dirt that may have accumulated.
In normal use, the measuring device does not require any maintenance.
The front of the measuring device should be wiped with a dry cloth only. Use minimum pressure
and never apply pressure to the tinted viewing window. If necessary, the rear can also be wiped
with a dry cloth. Only isopropyl alcohol can be used as a cleaning agent and should be used sparingly.
Never use water. If the rear of the device or the terminals should be accidentally contaminated with
water, the measuring device must be dried carefully before further service. If it is suspected that
water or another contaminant might have entered the device, the device must be examined and
overhauled at the factory.
All terminals must be examined regularly for corrosion and to ensure that the terminal connections
have not become loose. This is particularly important if the device is exposed to vibrations.
