1. Safety instructions

The transformer with rectifier conforms to the

safety regulations for electrical measuring, con-

trol, monitoring and laboratory equipment, as

specified under DIN EN 61010, section 1, and is

designed to be classified as protection class I

equipment. It is intended for operation in a dry

environment as this is 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 is deemed that the equipment can no longer

be operated without risk (e.g. visible damage

has occurred), the equipment should be

switched off immediately and secured against

any unintended use.

In schools and other educational institutions, the

operation of the AC/DC power supply unit must

be supervised by qualified personnel.

Caution: the low-voltage outputs of the power

supply are not surge-proof if exposed to external

voltages of more than 2000 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 2000 V with respect to earth are

present at the outputs.

• Before putting the DC power supply unit into

operation, confirm that the specifications

printed on the rear side of the housing are

compatible with the local mains voltage.

• Before putting the DC power supply unit into

operation, check the housing for any dam-

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. Never cover the air vents and heat sink at the rear of the housing.
