10.5.1 External power supply unit
WARNING
Danger of lethal injury due to hazardous electric voltage
−
Connect power supply units generating protective extra-low voltage (24
V) only to supply voltages designed for these power supply units. Note
the overvoltage categories (refer to the documentation of the power
supply unit).
−
Do not apply the supply voltage to the protective extra-low voltage.
All control components are supplied from 24
V voltage supplies (SELV/PELV, NEC class 2).
The power supply units used have to be able to deliver the quadruple nominal current of the internal
and external fuses to ensure that the fuse reliably triggers in case of an error.
All lines of the 24 V voltage supply have to be routed separately from lines carrying higher voltages.
All peripherals, such as digital sensors or actuators connected to the interfaces of the control, also have
to comply with the criteria of safety-separated circuits.
The 24 V voltage supply can be grounded. For more detailed information, refer to the docu-
mentation of the power supply unit.
Use only power supply units that can bridge a half-wave failure (10 ms).
10.5.2 Power connector XD10
The control is supplied via the XD10 power connector.
Use only copper wires to connect the connection terminals.
Only the power connector is permitted to connect the 24 V supply voltage for the control (see
Chapter 5.1 “Power connector, 24 V” on page 11
The power connector has a maximum number of 50 mating cycles. The mating cycles of the
cables in the XD10 supply connectors are limited to 50.
