1. Safety instructions
The transformer with rectifier 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 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
supply are not surge-proof if exposed to external
voltages of more than 2000 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 in
excess of 2000 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-
