
Devices with an earth terminal must always be grounded.
– If an earth connection (green-yellow laboratory socket) is available, it must always be
connected to protective earth. Protective earth must always be connected first (before voltage),
and must always be disconnected last (after voltage).
– Some devices have a high leakage current. These devices must be additionally grounded
with a protective earth conductor.

The device is not equipped with an integrated fuse unless specified otherwise in the technical data.

Always pull on the plug when disconnecting connecting cables; never pull the cable.

Risk of death in case of interrupted protective earth conductor!
– The protective earth conductor (yellow/green) must never be interrupted,
either inside or outside the device.
– The insulation of the protective earth conductor must never be damaged or removed.

National regulations for operating electrical systems and equipment must be observed in commercial
facilities.

In schools and training facilities, the operation of power supply units must be responsibly monitored by
trained personnel.

Caution!
The capacitors in the device may still carry a charge, even after it has been disconnected from all
voltage sources.

When replacing fuses, only use specified fuses with the correct current rating.

Never switch the device on immediately after it has been moved from a cold room to a warm room.
Under unfavourable conditions, the condensate which forms as a result may damage the device. Leave
the device switched off until it has reached room temperature.

Risk of death from connecting power supply units in series!
Contact voltages > 25 V DC are not permissible.
Coming into contact with voltages of greater than 120 V DC may be fatal.
– Do not connect voltage sources in series.

Device ventilation slots must not be covered! The devices must be placed on hard, flame-resistant
surfaces so that air can enter them unhindered. The devices are cooled primarily by means of
convection.

Set the devices up so that activation of switches and disconnectors is not made difficult.

When working on a live circuit, use only suitable tools.
