1. Safety instructions
The 0 – 500 V DC power supply conforms to all
safety regulations for electrical measuring, con-
trol, monitoring and laboratory equipment, as
specified under DIN EN 61010, Section 1, and
the equipment has been designed to meet pro-
tection class I. It is intended for operation in a dry
environment, suitable for the operation of electri-
cal 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 may be assumed for any reason that non-haz-
ardous operation will not be possible (e.g. visible
damage), the equipment should be switched off im-
mediately and secured against any unintended use.
In schools and other educational institutions, the
operation of the power supply unit must be super-
vised by qualified personnel.
Caution: the low-voltage outputs of the
power supply are not surge-proof if exposed to
external voltages of more than 500 V with respect
to earth.
•
When using the equipment in conjunction
with other power supplies, e.g. for operating
electron tubes, be careful that no voltages

•
Before using the power supply unit for the first
time, confirm that the specifications printed
on the rear side of the housing are compatible
with the local mains voltage.
•
Before using the power supply unit for the first
time, check the housing and the mains lead
for any damage. In the event of any malfunc-
tion/operational defect or visible damage,
switch off the unit immediately and secure it
against unintended use.
•
The instrument may only be connected to the
mains via a socket that has an earth connec-
tion.
•
Before making any connections, check the
experiment leads for damaged insulation and
exposed wires.
•
Replace a faulty fuse only with one matching
the specifications stated at the rear of the
housing.
•
Disconnect the equipment from the mains be-
fore replacing a fuse.
•
Never short the fuse or the fuse holder.
•
Never cover the air vents in the housing. This
is necessary to ensure sufficient circulation of
air required for cooling the internal compo-
nents of the equipment.
