1. Safety instructions
The DC power supply unit conforms to the
safety regulations for electrical measuring, con-
trol, monitoring and laboratory equipment, as
specified under DIN EN 61010, section 1, and is
designed to be classified as protection class I
equipment. It is intended for operation in a dry
environment as this is suitable for the operation
of electrical equipment and systems.
Safe operation of the equipment is guaranteed,
provided it is used correctly. However, there is
no guarantee of safety if the equipment is used
in an improper or careless manner. If it is
deemed that the equipment can no longer be
operated without risk (e.g. visible damage has
occurred), the equipment should be switched off
immediately and secured against any unin-
tended use.
Caution: the low-voltage output of the
power supply is not surge-proof if exposed to
external voltages of more than 100 V with re-
spect to earth.
•
When using the equipment in conjunction
with other power supplies, e.g. for operating
electron tubes, be careful that no voltages in
excess of 100 V with respect to earth are
present at the outputs.
•
Before putting the DC power supply unit into
operation, confirm that the specifications
printed on the rear side of the housing are
compatible with the local mains voltage.
•
Before putting the DC power supply unit into
operation, check the housing for any dam-
age. In the event of any malfunc-
tion/operational defect or visible damage,
