This operating manual explains the function and operation, describes the installation and
provides guidelines on how to connect the product.
1.1.1 Retaining the documentation
This documentation is intended for instruction and should be retained for future reference.
1.1.2 Terminology: System environment A and B
The PSSu system can be used in two different system environments. The module's applic-
ation area is described in the chapter "Intended Use" of the manual.
The distinction is made between
}PSSu in system environment A
}PSSu in system environment B
The distinction is based on the application area of the PSSu system.
PSSu in system environment A may be used in the
}Decentralised system PSSu I/O
}Not in the automation system PSS 4000
PSSu in system environment B may be used in the
}Automation system PSS 4000, e.g. with

The module PSSu E F PS2-T is suitable for use where there are increased environmental
requirements (see Technical Details).
The module PSSu E F PS2-R is suitable for use where there are increased environmental
requirements demanded by railway applications (see Technical details).
When using the module for railway applications, a mains filter should be connected up-
stream in order to comply with the limit values for conducted high frequency interference
voltages on the supply voltage connections, in accordance with EN 50121-4. The mains fil-
ter must have suitable properties, such as the Schaffner mains filter, type FN2070-3.
Intended use includes making the electrical installation EMC-compliant. Please refer to the
guidelines stated in the "PSSuniversal Installation Manual". The module is designed for use
in an industrial environment. It is not suitable for use in a domestic environment, as this can
lead to interference.

4.2 Module features
4.2.1 Supply voltage
The product provides the module supply and periphery supply for the modules on the mod-
ule bus:
}Module supply
Supply voltage for subsequent module (right-hand side)
}Periphery supply
Supply voltage for sensors, actuators and test pulses
}C-rail
Infeed of the permitted additional supplies for the C-rail; a detailed description of how to
use the C-rail can be found in the system description.
When the supply voltage is fed in separately, the module supply and periphery supply are
galvanicaly isolated. If galvanic isolation is not required, a common power supply may be
used for the periphery supply and module supply.
The module enables
}The module supply and periphery supply to be refreshed:
The relevant base module interrupts the connection to the incoming (left-hand) module
supply, periphery supply and C-rail on the module bus. The 0 V supply on the module
supply is connected to the left and right.
}Supply groups to be formed
The relevant base module interrupts the connection to the incoming (left-hand) peri-
phery supply and C-rail on the module bus. Each supply group requires its own supply
module.

4.2.1.1 Current load capacity
Ensure you comply with the current load capacity of the module and periphery supply (see
"Technical Details"). If the current load is higher, an additional supply voltage module is re-
quired to refresh the module supply and periphery supply.
}Module supply
The current load is the total current consumption of all the electronic and compact mod-
ules.
The module supply does not automatically switch off if values exceed or drop below
their limits. However, the "5 V" LED will light and a message will be entered in the dia-
gnostic log.
}Periphery supply
The current load is the total current consumption of the sensors, actuators and test
pulses supplied via the input/output modules.
The periphery supply does not automatically switch off if values exceed or drop below
their limits. However, the "24V" LED will light and a message will be entered in the dia-
gnostic log.
Please refer to the derating diagram.
}C-rail
If the current load is higher, the C-rail must use a different supply to prevent overload.
Please refer to the derating diagram.

5.2 Installing the base module
Prerequisite:
}The head module must be installed.
}If the head module does not have an integrated power supply, a supply voltage module
must be installed to the right of the head module.
Please note:
}For mechanical reasons it is not possible to mix base modules with screw terminals and
base modules with cage clamp terminals.
}All contacts should be protected from contamination.
}The mechanics of the base modules are designed for 50 plug in/out cycles.
Procedure:
}We recommend that you wire up the base modules before inserting the electronic mod-
ules.
}Slot the groove on the base module on to the mounting rail from below [1].
}Push the base module back [2] until you hear it lock into position.
}On the mounting rail, slide the base module to the left until you hear the two lateral
mounting hooks on the adjacent module lock into position [3].

5.3 Inserting and removing an electronic module
Please note:
}Only insert on to base modules that are already installed.
}Preferably these base modules should be ready wired.
}Electronic modules with outputs may only be inserted and removed when the load is
switched off. Unforeseeable error reactions may be triggered if modules are inserted
and removed under load.
}When an electronic module is plugged into a base module for the first time, one part of
the coding element remains on the electronic module, while its counterpart is fixed on to
the base module. This is how the base module is coded.
}The mechanics of the electronic modules are designed for 50 plug in/out cycles.

5.3.3 Changing an electronic module during operation
It is possible to change an electronic module during operation. The configuration data is re-
tained when a module is changed.
Effects:
}System environment A:
– In the event of a potential FS communication error, the FS section of the PSSu sys-
tem and all relevant I/O-Groups (SafetyBUS p) switch to a STOP condition.
}System environment B:
– All FS hardware outputs on the PSSu system switch to a safe condition.
– The substitute values are used for the modules' FS outputs, with Valid Bits =
FALSE.
CAUTION!
Sparking can cause interference and errors!
Only change the module when the load is switched off!

6 Wiring
6.1 General wiring guidelines
Please note:
}The requirements of the supply voltages can be found in the chapter entitled "Technical
Details".
}Protective separation must be ensured for the external power supplies that generate
the supply voltages. Failure to do so could result in electric shock.
}The external power supplies must comply with the current applicable standard EN
60950-1, EN 61140, EN 50178 or EN 61558-1.
}The maximum current load for the periphery supply on the module bus is 10A. Please
refer to the derating diagram in the chapter entitled "Function Description".
}Earth the 0 V supply on the periphery supply or monitor each supply group for earth
faults.
}The connection of the 0 V supply to the central earth bar or earth fault monitor must be
in accordance with relevant national regulations (e.g. EN60204-1, NFPA 79:17-7,
NEC:Article 250).
}Details of the minimum range for conductor cross sections on connection terminals can
be found in the section entitled "Technical Details".
}Use copper wiring.
6.1.1 Mechanical connection of the base modules
Procedure:
}Use a flat blade screwdriver (DIN 5264-A)!
DIN 5264-A
}Strip the wire back 8 mm.
}If necessary, label the connection level with a colour marker [3].
}Base module with screw terminals:
– Use a screwdriver to loosen the screw on the screw terminal [1]
– Insert the stripped cable into the round fixing hole [2], as far as it will go.
– Tighten up the screw on the screw terminal.
– Check that the cable is firmly seated.
