• If you are using the PS 60W 24/48/60VDC HF, the 24 V supply of the CPU is not taken into
account in the power budget calculation.
You may only connect the 24
V
DC supply voltage directly to the system power supply and
not to the CPU.
You must set the "System power supply" parameter to the option "No connection to supply
voltage L+" during configuration of the CPU. STEP 7 checks the setting when compiling
the configuration.
