1. Safety instructions
The transformer with rectifier 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-
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 power supply unit must be su-
pervised 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 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
