Note
When connecting an external 24 V DC power supply to interfaces X515/ X516, this must satisfy
the requirements of a protective extra low voltage (PELV) according to UL 61010. A backup fuse
must also be used which safely trips within 120 seconds at an ambient temperature of 0 °C for
a current of 6.5 A.
Alternatively, a circuit must be used that limits the current to 5 A within 60 seconds during
normal operation and in the event of an individual error.
The contact gap of the fuse or the individual error-proof circuit must be ensured with 3.0 mm
according to UL 61010 for a primary power supply from OVC III circuits up to 600 V AC (line-to-
neutral voltage).
When using an external power supply, make sure that the fuse used has a tripping rating that
corresponds to the maximum possible short-term short-circuit current of the power supply unit
used.
