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.

PHYSICS

•

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.

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.
