1. Safety instructions

The 0-20 V/5 A AC/DC power supply unit con-

forms to all safety regulations for electrical meas-

uring, control, monitoring and laboratory equip-

ment, as specified under DIN EN 61010, Sec-

tion 1, and the equipment has been designed to

meet protection class I. It is intended for opera-

tion in a dry environment, suitable for the opera-

tion 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 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 500 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 500 V with respect to earth are

present at the outputs.

• Before using the AC/DC power supply unit

for the first time, confirm that the specifica-

tions printed on the rear side of the housing

are compatible with the local mains voltage.

• Before using the AC/DC power supply unit

for the first time, check the housing 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. 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. Never cover the air vents in the housing. This is necessary in order to ensure sufficient circulation of air required for cooling the internal components of the equipment.

6. Care and maintenance • • Before cleaning the equipment, disconnect it from its power supply. Use a soft, damp cloth to clean it. 7. Disposal • • The packaging should be disposed of at local recycling points. Should you need to dispose of the equipment itself, never throw it away in normal domestic waste. Local regulations for the disposal of electrical equipment will apply. Elwe Didactic GmbH ▪ Steinfelsstr. 5 ▪ 08248 Klingenthal ▪ Germany ▪ www.elwedidactic.
