1.3.1 Safety Information
The instrument complies with the electrical protection class 1 in accordance
with the EU Directive 2006 / 95 / EC (Low Voltage Directive). With correct
mains connection and intended use, exposure to electric current is prevented
by the closed, grounded metal housing.
The instrument is subjected to the EU Directive 2004 / 108 / EC (EMC
Directive) and therefore complies with the limit values for emission and
immunity of the standards they are based on (refer also to
SECTION

Impairment caused by radio interference ! This device is subjected to Limit Class A and
can cause radio interferences in residential areas. In this case, the user has to carry out
appropriate measures.
1.3.2 Safety Precautions
Pay attention to the following safety precautions when using the instrument:
•
The instruments may only be connected up using a three-pin mains cable
to AC systems 50 / 60 Hz with a grounded protective conductor, and a
nominal voltage of between 100 V and 240 V.
•
Defective mains fuses may only be replaced by fuses of the same kind
with the rating given on the instrument.
•
If the mains switch is not freely accessible the mains plug is used as a
separator in case of danger. This means that the mains plug needs to be
freely accessible. Otherwise an additional disconnection device must be
installed.
•
The housing may not be opened when using the instrument as intended.
Opening the housing will invalidate the warranty. None of the instruments
may be operated with opened housing.
•
Maintenance and repair work may only be carried out by the manufacturer
or by qualified persons authorized by the manufacturer.
•
Disconnect the mains plug before you remove parts of the housing for
installation and servicing purposes.
•
Existing air inlets and outlets must always be kept free to allow sufficient
cooling. If you notice that a cooling fan is not working, immediately switch
off the affected instrument.
