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 II. It is intended for operation in a
dry environment, 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 may be assumed for any reason that non-
hazardous 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 su-
pervised by qualified personnel.
It is not permissible to cascade multi-
ple devices and short them out. This
causes overloading of the polyswitch.
• 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
malfunction/operational defect or visible
damage, switch off the unit immediately and
secure it against unintended use.
• 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
before replacing a fuse.
• Never short the fuse or the fuse holder.
• The equipment may only be opened/repaired
by qualified and trained personnel.
