5 Work and safety instructions

General
•
Trainees should only work with the circuits under the supervision of an instructor.
•
Observe the specifications included in the technical data for the individual components, and in
particular all safety instructions!
•
Malfunctions which may impair safety must not be generated.
•
Wear personal safety equipment (safety glasses, safety shoes) when working on circuits.
Electrical system
•
Risk of death in case of interrupted protective earth conductor!
– The PE conductor (yellow-green) must not be interrupted, either inside or outside of the device.
– The insulation of the protective conductor must never be damaged or removed.
• Risk of death from connecting power supply units in series!
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 cables connected to them
from direct contact.
– Only use 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 being disconnected from all sources of
voltage.
• 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.
