2.3 Device-specific hazards
2.3.1 Direct/indirect contact
▶
For all the components connected to the system, ensure protection
against direct and indirect contact in conformity with VDE 0100 Part 410.
No cases of hazardous accidental energization must occur in the event of a
fault (safety under single-fault conditions!).
2.3.2 Power supply units for 24 V supply
▶
Only use power supplies with safe isolation and SELV / PELV voltage.
▶
Protect the 24 V system with a suitable external fuse.
▶
Make sure that the power supply can deliver
four times
the rated cur-
rent of the external fuse so as to ensure that the fuse will blow reliably in
the event of a fault.
▶
Make sure that the output voltage of the power supply does not exceed
24 VDC -15%/+10% even in the event of a fault.
2.3.3 Mismatching and polarity reversal of connections
▶
Take measures to prevent mismatching, polarity reversal, and manipula-
tion of connections.
