Warning
Attention
Before startup, verify that the following conditions have been met:
• The Mains has been connected correctly and protection is provided against electric shock.
• The device can be switched off outside the power supply according to EN 60950 regulations (such as by the line
protection on the primary side).
• The protective conductor is connected.
• All supply lines have sufficient fuse protection and are the correct size.
• All output cables are the correct size for the maximum device output current or have separate fuse protection.
• Sufficient convection is ensured.
Attention

The device contains dangerous live elements and high levels of stored energy. Never
carry out work when power is applied.
Risk of burns. The housing temperature can reach high values depending on the
ambient temperature and the load of the device.
Make sure that all output cables are the correct size for the maximum output current
or have separate fuse protection. The cable cross sections in the secondary circuit must
be large enough to keep the voltage drops on the cables as low as possible. Further
recommendations are given with the individual power supply descriptions provided in
this document.
An internal fuse is provided for device protection. Branch circuit protection external
to the supply is recommended to guard wiring and connections. For dc input
applications, the external fuse or circuit breaker must be rated for dc operation.
Further recommendations are given with individual supply descriptions provided in
the following sections of this document.
If the internal fuse is blown, this is most probably due to component failures in the
power supply. In this case, the power supply should be checked in the factory.
