5 Work and safety instructions

General
•
Trainees should only work with the circuits under the supervision of an instructor.
•
Observe the specifications in the datasheets for the individual components, and in particular all safety
instructions.
•
Malfunctions which could impair safety must not be generated.
•
Wear personal safety equipment (safety goggles, safety shoes) when working on circuits.
Mechanical system
•
Switch off the power supply!
– Switch off both working and control power before working on the circuit.
– Only reach into the setup when it's at a complete standstill.
– Be aware of potential run-on times of the actuators.
•
Set all components up so that activation of switches and disconnectors is not made difficult.
•
Follow the instructions regarding positioning of the components.
Electrical systems
• 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 series connection of power supply units!
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 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 datasheets and operating
instructions included with the respective components.
