● PM 70W 120/230VAC: Supply voltage with 120/230 V AC and infeed power to the
backplane bus of 70 W
● PM 190W 120/230VAC: Supply voltage with 120/230 V AC and infeed power to the
backplane bus of 190 W
Also note the following FAQ on the You can use system power supplies with the CPUs and the interface modules IM 155-
5 PN ST and IM 155-5 PN HF.
If the power fed from the CPU/interface module into the backplane bus is not sufficient to
supply all connected modules with power, system power supplies (PS) are required.
Whether or not you need a system power supply depends on the power consumption of the
modules used. The power supplied by the CPU/interface module and the system power
supplies must be greater than the power required by the I/O modules.
During configuration, STEP 7 compares the supplied power and the power required by the
modules. If the required power is too high, you receive a corresponding message from
STEP 7.
In addition, the system power supply PS 60W 24/48/60V DC HF buffers the power in the
event of power failures and therefore enables the retentivity of the data of a CPU – without a
battery and therefore maintenance-free.
Slots for system power supplies
The following slots may be used for system power supplies:
● A system power supply in slot 0 to the left of the CPU/interface module
● Up to 2 system power supplies in the slots to the right of the CPU/interface module
(power segments) A power segment consists of a power supply module and the modules
supplied by it.
Note
The system power supply PS 60W 24/48/60V DC HF can only be inserted in slot 0.If you use the TIA Portal for configuring, it automatically checks the configuration for
consistency and informs you as of which module you must open up a new power segment.
Overload in the power segment
If an overload occurs in the power segment, the red SF LED on the system power supply
(PS) flashes. All I/O modules to the right of the PS in the power segment will be switched off.
Remedy:
1. Correct the configuration in the power segment of the overloaded PS.
2. Switch the supply voltage power off and on again via the on-off switch on the PS.
3. Switch the CPU from STOP to RUN mode.
Reference
Information about the required power is available in the section Power balance calculation

Page 104).
Additional information on the performance values (power feed, power consumption) of the
CPU, interface module, system power supply, and I/O modules can be found in the manuals There are three options for the infeed of the required system voltage in the backplane bus:
● Infeed via CPU/interface module
● Infeed via CPU/interface module and system power supply
● Infeed only via system power supply in slot 0
Infeed via CPU/interface module
Infeed via the CPU/interface module generally suffices for small and medium hardware
configurations. The power consumption of the connected modules must not exceed the
power supplied by the CPU/interface module.
In this configuration variant, supply the CPU/interface module with 24 V DC from a load
current supply.
Procedure
To set up the supply by means of the CPU/interface module, follow these steps:
1. Open the "Properties" tab of the CPU/interface module in STEP 7 and select the "System
power supply" in the navigation.
2. Select the option "Connection to supply voltage L+For larger hardware configurations, infeed into the backplane bus by the CPU/interface
module alone no longer suffices. If the modules consume more power in total than the power
supplied by the CPU/interface module, you must insert an additional system power supply.
Supply the system power supply with the permissible supply voltage and the CPU/interface
module with 24 V DC.
Both the system power supply and the CPU/interface module feed current into the backplane
bus. The supplied power is summed.
Power addition: "Infeed power of the system power supply" + "Infeed power of the
CPU/interface module"To set up the supply by means of the CPU/interface module and system power supply,
follow these steps:
1. Open the "Properties" tab of the CPU/interface module in STEP 7 and select the "System
power supply" in the navigation.
2. Select the option "Connection to supply voltage L+".As a further possibility you can supply the required power to the backplane bus using only a
system power supply (in slot 0). In this case, the CPU/interface module is not supplied with
24 V DC, and draws its supply from the backplane bus. The system power supply must be
inserted to the left of the CPU/interface module for this.
In general, you can use system power supplies with AC or DC infeed for the configuration.
If no supply voltage with 24 V DC is present (and e.g. only CMs/CPs are inserted next to the
CPU), you can use a system power supply with 230 V AC because the CMs/CPs are
supplied via the backplane bus.
