Power supply
The 24 V terminal supplies the CP 263/x and all add-on modules.
To avoid problems with the electrical potential and stray electric current all 0
V potential have to be linked on a neutral point with a ground rail.
Additionally a shield rail for the connections of all shields of the cables has to
be used.
WARNING!
Danger of personal injury due to electric shock!
●
Supply the device exclusively from power sources that have an extra low
voltage (e.g. SELV or PELV according to EN 61131-2)
●
When using a SELV power source it can become PELV by reason of the
module construction and the connectors (grounding!).
●
Protective low voltage circuits must always be installed safely insulated
separated from circuits with dangerous voltage.
CAUTION!
Fire hazard during module failure!
●
External line fuse with maximum 10 A must be provided in the final appli-
cation.
Section
Refer to the manufacturer-specific data sheet of the of the female connectors
used for type, cross-section and material. For further information: See chapter
Accessories.
The actual permissible wire cross-section is specified by the electrical condi-
tions of the connected equipment an the female connectors used:
●
Max. load current and required heat dissipation through the connected wire
at maximum ambient temperature.
●
Permissible voltage drop for error-free operation of the connected equip-
ment.
