6.1 Power supply
WARNING!
Danger of personal injury due to electric shock!
● Supply the device exclusively from power sources that have a safety ex-
tralow voltage or protective low voltage (e.g. SELV or PELV according to
EN 61131-2).
● When using a SELV power source it can become PELV due to the archi-
tecture of the module and the connectors (grounding!).
● Protective low voltage circuits must always be installed safely insulated
separated from circuits with dangerous voltage.
The following 24 V power supply connection is available:
● Power supply of the CP 50x/x
Power supply of the CP at the terminal "X00A"
The CP 50x/x is supplied with voltage via the terminal X00A. The terminal is
located on the lower right on the front side.
CAUTION!
Fire hazard during module failure!
External line fuse with maximum 10 A must be connected upstream in the fi-
nal application.
Information
The power supply unit on the 24 V secondary circuit has to provide bridging
of a 10 ms interruption of the voltage supply. Otherwise only 1 ms interrup-
tion at full load can be bridged.
Power supply for further modules at terminal "X00B"
The CP 50x/x has an additional power supply at the terminal X00B for the
optional connection of further modules. The terminal is located on the lower
right on the front side.
Information
The power supply at terminal X00B is directly looped through without safety
element from terminal X00A.
