The following special requirements apply to the connecting 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,...) from the "Power supply connectors for TCU30.3" 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 plug.
• Flame resistance of the 24VDC cable according to UL 2556 VW-1/ tested according to IEC
60332-1-2.
• Observe the permissible bending radii of the cables.
• Rotate the panel only in a way that does not cause pinching of the cables.
• Route all of the cables so that they do not come into contact with cha󹪝ng edges.
NOTICE
Warning for areas subject to NEC or CEC
Safety note for connectors with Ethernet marking:
