1. Safety instructions
The 0-20 V/5 A AC/DC power supply unit con-
forms to all safety regulations for electrical meas-
uring, control, monitoring and laboratory equip-
ment, as specified under DIN EN 61010, Sec-
tion 1, and the equipment has been designed to
meet protection class I. It is intended for opera-
tion in a dry environment, suitable for the opera-
tion 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 may be assumed for any reason that non-
hazardous operation will not be possible (e.g.
visible damage), the equipment should be
switched off immediately and secured against
any unintended use.
In schools and other educational institutions, the
operation of the AC/DC power supply unit must
be supervised by qualified personnel.

Caution: the low-voltage outputs of the power
When using the equipment in conjunction
with other power supplies, e.g. for operating
electron tubes, be careful that no voltages in
excess of 500 V with respect to earth are
present at the outputs.
Before using the AC/DC power supply unit
for the first time, confirm that the specifica-
tions printed on the rear side of the housing
are compatible with the local mains voltage.
Before using the AC/DC power supply unit
for the first time, check the housing and the
mains lead for any damage. In the event of
any malfunction/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 connection.
