Work and safety instructions
General
•
Trainees should only work with the circuits under the supervision of an instructor.
•
Observe the specifications included in the data sheets for the individual components and, in particular,
all safety instructions!
•
Set the devices up so that it is easy to activate switches and separators.
•
Faults which may impair safety must not be generated.
•
Wear personal safety equipment (safety glasses, safety shoes) when working on circuits.
Electrical Safety
•
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 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.
•
Attention: High leakage current!
Risk of fatal injury due to high leakage current in case of interruption to the PE conductor. Be sure to
establish a ground connection before connecting the power supply circuit. The device may only be
operated with an additional PE conductor.
•
Dangerous voltage!
After opening the housing, parts are accessible which may be charged with dangerous voltage. Switch
off the power supply before working on the device.
