Component sets for Electrical engineering/Electronics
•
Devices with a ground connection must always be grounded.
– If a ground connection (green-yellow lab socket) is available, connection to
protective grounding must be present at all times. Protective ground must always be connected
first (before voltage) and must always be disconnected last (after voltage disconnection).
– Some devices have a high leakage current. These devices must be additionally grounded
with a PE conductor.
•
Use protective extra-low voltage only: max. 24 V DC.
• The power supply unit must only be operated using a power supply with a PE conductor.
•
Establishing and disconnecting electrical connections
– Electrical connections may only be established in the absence of voltage.
– Electrical connections may only be disconnected in the absence of voltage.

Risk of death from series connection of power supply units!
Contact voltages of > 25 V AC or > 60 V DC are not permissible.
Coming into contact with voltages of > 50 V AC or 120 V DC may be fatal.
– Do not connect voltage sources in series.
Risk of death due to electric shock!
Protect the outputs of the power supply units (output sockets/terminals) and connector
cables connected to them from direct contact.
– Only use connector cables with adequate insulation and electric strength.
– Use safety sockets with fully shrouded contact points.
Disconnect from all sources of electrical power!
– Switch off the power supply before working on the circuit.
– Please note that electrical energy may be stored in individual components.
Further information on this issue is available in the data sheets and
operating instructions included with the components.
Caution!
–
Capacitors inside the device may still be charged even after the device
has been disconnected from all sources of voltage.
