DANGER
•
Risk of fatal injury in case of interrupted PE 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 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.
–
Use only cables with adequate insulation and electric strength.
–
Use safety sockets with fully shrouded contact points.
