4.2 Module features
4.2.1 Supply voltage
Module supply
}The module supply provides the module with voltage.
The product provides the periphery supply for the modules on the module bus:
}Refreshing the periphery supply: The relevant base module interrupts the connection to
the incoming (left-hand) periphery supply and C-rail on the module bus.
}Supply to the module bus:
– Periphery supply for subsequent modules (right-hand side)
– C-rail supply for subsequent modules (right-hand side)
}The periphery supply does not automatically switch off if values exceed or drop below
their limits. However, the "24V" LED will light and a message will be entered in the error
stack or diagnostic log.
4.2.1.1 Current load capacity
Ensure you comply with the current load capacity of the periphery supply (see "Technical
Details"). If the current load is higher, an additional supply voltage module is required to re-
fresh the periphery supply.
}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 er-
ror stack or diagnostic 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.

4.2.2 Integrated protection mechanisms
The module has the following protection mechanisms:
}Periphery supply
– Voltage monitoring (exceeding upper/lower limit)
The module registers the following errors:
}Start-up error
}Configuration error
}FS communication error
}Bus termination error
}Temperature error: too warm
}Overvoltage error
}Undervoltage error
}Error in the overvoltage protection diodes
4.3 Configuration
The module does not have to be configuriert.
4.3.1 Addresses in the process image
The module does not occupy any addresses in the process image.
4.3.2 FS error behaviour
In the case of a safety-related error on an FS output, all FS outputs in the affected I/O-
Group (SafetyBUSp) are shut down.
In the case of a safety-related error on an FS input, the process image of all FS inputs in
the affected I/O-Group (SafetyBUSp) is set to zero.
The I/O-Group switches to a STOP condition. An error telegram is then triggered on Safety-
BUS p and the error is entered in the PSSuniversal error stack.

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.
