The internal power supply voltage for the module's circuitry is carried out via the I/O bus (pro-
vided by a bus module or a CPU). Thus, the current consumption from 24 VDC power supply at
the terminals L+/UP and M/ZP of the CPU/bus module increases by 10 mA per DI571.
An external power supply connection is not needed.
WARNING!
Risk of death by electric shock!
The terminals of the module can carry 240 V voltage.
Make sure that all voltage sources (supply and process voltage) are switched
off before you begin with operations at the system.
