1. Safety instructions
The AC/DC Power Supply 0 - 30 V, 6 A conforms to all
safety regulations for electrical measuring, control,
monitoring and laboratory equipment, as specified
under DIN EN 61010, Section 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, pro-
vided it is used correctly. However, there is no guar-
antee of safety if the equipment is used in an im-
proper 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 se-
cured against any unintended use.
In schools and other educational institutions, the
operation of the power supply unit must be super-
vised by qualified personnel.
Caution: the low-voltage output of the power
supply is not surge-proof if exposed to external volt-
ages of more than 100 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 100
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, check the hous-
ing 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.
•
Before making any connections, check the experiment
leads for damaged insulation and exposed wires.
•
Any changes to the circuit may only be made with
the power supply switched off.
•
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.
