The “arrow” symbol is used where special tips and notes on operation are provided.

Protective earth wire connection. This contact/this screw may not be loosened.

Only to be used in dry indoor areas.

The product is CE-conform and meets the requirements of the current European

and national guidelines.

The unauthorized conversion and/or modication of the product is inadmissible for reasons of

safety and approval (CE).

If you have doubts about how the device should be operated or how to connect it safely,

consult a trained technician.

workers’ societies for electrical equipment and utilities must be follow ed.

Power supply units used at schools, training facilities, do-it-yourself and hobby workshops

should not be handled unless supervised by trained, responsible personnel.

The device will become warm during operation. Ensure there is sufcient ventilation provided;

do not cover the housing!

Handle the product with care. It can be damaged through impact, blows or drops, even from

a low height.

The design of the product complies with the safety class 1. Only supply the product with a

voltage from an earthed standard mains socket connected to the public supply grid. The

mains socket must be close to the device and easily accessible, or an emergency stop device

(e.g. glasses) in the vicinity.

Do not use the device in rooms or under unfavourable ambient conditions in which there are

or could be combustible gases, vapours or dust.

If safe operation is no longer possible, take the device out of service and secure it against

unintended use. Safe operation is no longer possible, if the product:

- has visible damage,

- no longer functions properly,

- has been stored under adverse ambient conditions for an extended period of time or

- has been exposed to considerable strain during transport.

Exclusively use fuses of the type and rated current specied. It is absolutely prohibited to use

The linear xed voltage power supply unit with electronic stabilisation is used to supply the

power of low-voltage consumer loads with a nominal operating voltage of 12 Volt. You can

The momentary output voltage is indicated on the display.

The power consumption of the consumer load must not exceed the nominal current of the

power supply unit (for this purpose, please observe the information in the technical data

section). If exceeded, the power supply unit may overload. If the power supply overloads, e.g.

due to a short-circuit or excessive current draw, the output will be shut off to avoid damage.

After removing the overload, the power supply unit can be put back into operation.

The interconnection of multiple power supply units to increase the voltage or current is not

permitted since this will lead to hazardous voltages which can cause an electric shock.

The power supply unit is not a charger. To charge rechargeable batteries, use suitable charg-

ers with a charging current cut-off.

If it is no longer possible to switch on the power supply unit, the device fuse is probably defec-

tive and has to be replaced.

Proceed as follows to replace the device fuse:

• Switch off the power supply unit and remove all the connection and mains cables.

• Release the bayonet lock on the fuse bracket (6) at the rear with slight pressure in the

direction of the arrow (a quarter turn). Pull the fuse insert out of the device.

• Replace the defective fuse with a new ne-wire fuse (5x20 mm) of the same type and rated

current. You can nd the fuse data in the technical data.
