WARNING
Warning for areas subject to NEC or CEC:
Safety notice for connectors with Ethernet marking:
A Ethernet or Ethernet segment, with all its associated interconnected equipment, shall be
entirely contained within a single low-voltage power distribution and within a single building.
The Ethernet is considered to be in an "environment A" according IEEE802.3 or "environment
0" according IEC TR 62102, respectively.
Never make direct electrical connection to TNV-circuits (Telephone Network) or WAN (Wide
Area Network).
Note
When connecting an external 24 V DC power supply to the interfaces, it must meet the
requirements of a protective extra low voltage (SELV/PELV) according to UL 61010. A series fuse
must also be used, which reliably trips within 120 seconds when a short-circuit occurs at an
ambient temperature of 0 °C.
For a primary supply of the power supply used from OVC III circuits up to 600 V AC (line to neutral
voltage), it must be ensured that the contact gap of the fuse – or the individual fault-proof circuit
– is 3.0 mm according to UL 61010.
When using an external power supply, ensure that the fuse used has a trip rating that
corresponds to the maximum possible short-term short-circuit current of the power supply unit
being used.

SIMATIC connection box
4.4.1
Description
Two versions of the SIMATIC connection box are available.
• Connection box standard
The connection box standard is intended for use outside the control cabinet.
The connection box standard can be used if hot plugging is not required. The Emergency Stop
circuit can be overridden here by external mechanisms.
• Connection box advanced
The connection box advanced is intended for use outside the control cabinet.
The connection box advanced can be hot plugged. This means that it is possible to connect
and disconnect during operation without any disruption.
The emergency stop circuit is automatically maintained during the switching of connectors.
The connection box advanced also has:
– Real-time Ethernet
– F signal override
