•
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 > 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 being disconnected
from all sources of voltage.
