The internal power supply voltage for the module's circuitry is carried out via the I/O bus
(provided by a communication interface module or a CPU). Thus, the current consumption from
24 V DC power supply at the terminals L+/UP and M/ZP of the CPU/communication interface
module increases by 10 mA per DI572.
An external power supply connection is not needed.
WARNING!
Risk of death by electric shock!
Hazardous voltages can be present at the terminals of the module.
Make sure that all voltage sources (supply voltage and process supply voltage)
are switched off before you begin with operations on the system.
