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 protective 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 greater than 25 V AC or 60 V DC are not permissible.
Coming into contact with voltages of greater than 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 respective 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.
