The following special requirements apply for the connection cables:
● The 24 VDC cable must be approved for temperatures up to 70° C.
● Select the permitted conductor cross-section in accordance with the national regulations
(NEC, VDE, etc.) and the "Power supply connectors for MCP 398C" table below. The line
protection in accordance with the national regulations (NEC, VDE,...) must be guarantied
as appropriate for the selected conductor cross-section.
● Strip the cables (7 mm) for connection to the 24 VDC connector.
● Flame resistance of the 24 VDC cable in accordance with UL 2556 VW-1 / or tested in
accordance with IEC 60332-1-2.
● Observe the permissible bending radius of the cables.
● Only rotate the panel in a way that does not cause pinching of the cables.
● Route all of the cables in such a way that they do not come into contact with chafing edges.
Note
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).
Pin assignment
The pin assignments of the interfaces are described in Section "Connect" > "Pin assignment
of the interfaces" (Page 39).
