1 Safety Instructions

Impedance stabilization networks (ISN) can operate at dangerously high voltages.
Improper or careless handling can be fatal!
Use of the ISN is restricted to authorized and trained specialists for the applications
described in this operating manual.
For measurements in circuits with voltages which are above the following limits,
additional measures must be taken to protect the user against direct or indirect contact.
If the value for the voltage in accordance with a) is exceeded, the limits for the current
in accordance with b) must not be exceeded.
a) The limits for the voltage (safety extra low voltage, SELV) are as follows:
30 V
b) The limits for the current are:
0.5 mA
for mixed frequency and 2.0 mA for DC current.
Improper or careless handling can be fatal!
If the limits for the SELV voltage are exceeded, all contacts should be made in power
OFF stage.
It is recommended to use a blocking loop to ensure automatic protection against
accidental contact.
These operating instructions form an integral part of the equipment and must be
available to the operating personnel at all times. All the safety instructions and advice
notes are to be observed.
Neither Rohde & Schwarz GmbH Co. KG nor any of the subsidiary sales organizations
or the manufacturer can accept any responsibility for personal injury or material
damage that results from improper use of the equipment and accessories.
