1. Safety instructions
The AC/DC Power Supply 1/ 2/ 3/ … 15 V, 10 A
conforms to all safety regulations for electrical
measuring, control, monitoring and laboratory
equipment, as specified under DIN EN 61010, Sec-
tion 1, and the equipment has been designed to
meet protection class I. 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 super-
vised by qualified personnel.
•
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 connection.
•
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.
