1. Safety instructions
The plug-in power supply 24 V conforms to all
safety regulations for electrical measuring, control,
monitoring and laboratory equipment, as specified
under DIN EN 61010, Section 1, and the equip-
ment has been designed to meet protection
class II. It is intended for operation in a dry envi-
ronment, 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. visi-
ble damage), the equipment should be switched
off immediately and secured against any unin-
tended use.
In schools and other educational institutions, the
operation of the plug-in power supply must be
supervised by qualified personnel.
• Before using the plug-in power supply for the
first time, confirm that the specifications
printed on the housing are compatible with
the local mains voltage.
• Before using the plug-in power supply, check
it for any damage. In the event of any mal-
function/operational defect or visible dam-
age, switch off the unit immediately and se-
cure it against unintended use.
2. Description
The plug-in power supply supplies an AC voltage
of 24 V. It is especially suitable as a power
source for the electric motor used with the Pohl's
torsion pendulum (1002956).
It is moulded in an impact-resistant plastic block,
and is provided with two 4 mm safety plugs.
The plug-in power supply is available in 2 ver-
sions for differing mains voltages. The plug-in
power supply with the order number 1000681 is
for mains supplies of 230 V (±10%) while the one
with order no. 1000680 is for 115 V (±10%) sys-
tems.
