The following table provides an overview of the most important components of the S7-1500
automation system:
Table 2- 1 Components of the S7-1500 automation system
Components Function Diagram
Mounting rail The mounting rail is the rack of the S7-1500 automation system.
Components according to EN 60715 (modules from the S7-1200 and
ET 200SP ranges, terminals, circuit breakers, small contactors or
similar components) can be mounted directly on the integrated
standard tophat profile in the lower part of the mounting rail. You can
use the entire length of the mounting rail in the assembly (marginless
assembly).
The mounting rails may be ordered as accessories (Page 193).
PE connection element
for mounting rail
The set of screws is threaded into the mounting rail's T-profile groove,
and is required for grounding the mounting rail.
The set of screws is contained in the scope of delivery of the mounting
rails in the standard lengths (160 to 830 mm), and may be ordered as
an accessory (Page 193).
System power supply
(PS)
The system power supply is a diagnostics-capable power supply
module, that can be connected with the backplane bus using a
U connector.
A system power supply is required, if the power fed from the CPU into
the backplane bus is not sufficient to supply the connected modules
with power.
System power supplies are available in various models:
•PS 25W 24V DC
•PS 60W 24/48/60V DC
•PS 60W 120/230V AC/DC
A power cable connector with coding element and a U connector are
included in the scope of delivery of the system power supply, and may
be ordered as a spare part (Page 193).

Shielding bracket The shielding bracket is an insertable bracket for modules with
EMC-critical signals (e.g., analog modules, technology modules), and
(together with the shielding clamp) permits the low impedance
application of shielding with minimal installation times.
The shielding bracket is included in the scope of delivery of the analog
and technology modules, and may be ordered as an accessory
(Page 193).
Shield clamp The shield clamps are used to attach cable shielding to the shielding
bracket.
The shield clamp is included in the scope of delivery of the analog and
technology modules, and may be ordered as an accessory
(Page 193).
Power supply element The power supply element is inserted in the front cable connector, and
serves to supply power to modules with EMC-critical signals (analog
modules, technology modules).
The power supply element (connection technology: screw terminal) is
included in the scope of delivery of the analog and technology
modules, and may be ordered as an accessory (Page 193).
Labeling strips for the
exterior of the front
cover of the
I/O modules
Labeling strips can be inserted for the system-specific labeling of
modules. The labeling strips can be printed, and are available in
various colors.
The labeling strips are included in the scope of delivery of the
I/O modules. Additional labeling strips may be ordered as Accessories
(Page 193).
4-pole connection plug
for supply voltage of
the CPU
In the delivery condition of each CPU a 4-pole connection plug is
plugged on the CPU.
Load current supply
(PM)
A load current supply supplies the S7-1500 automation system
through a front connector of the CPU. A load current supply does not
occupy a slot in the configuration and is not included in the system
diagnostics.
If you are using load current supplies, we recommend the devices
from our SIMATIC series. These devices can be mounted on the
mounting rail.
The load current supply can be planned using STEP 7.
Load current supplies are available in various models:
•PM 70W 120/230V AC
•PM 190W 120/230V AC
