– Cage clamp terminals
The base modules are the carrier units for the electronic modules and are used to connect
the field wiring. The electronic modules are inserted on to the base modules and determine
the module's function.
Details of the base modules that can be used are available in the chapter entitled “Intended
Use”.
2.2 Module features
The product has the following features:
}The module routes the periphery supply from the module bus to the base module ter-
minals.
}LED for:
– Periphery supply
}Application range depends on the base module
}T-type:
PSSu E PD-T: for increased environmental requirements

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!

6.1 General wiring guidelines
Please note:
}Use copper wiring.
}The terminal configuration as stated on the front plate applies for base modules with C-
rail. The terminal configuration as stated in the technical documentation applies for all
other base modules.
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.
}Base module with cage clamp terminals:
– Insert the screwdriver [4] into the square hole [1].
– Insert the stripped cable into the round fixing hole [2], as far as it will go [5].

Please note:
}The minimum cable cross section for field connection terminals on the base modules is
0.14mm2 (AWG26).
}The maximum cable cross section for field connection terminals is:
– Digital inputs: 1.5mm2 (AWG16)
– Digital outputs: 2.0 mm2 (AWG14)
– Inputs/outputs on the counter modules: 1.5mm2 (AWG16)
– Analogue inputs/outputs: 1.5mm2 (AWG16)
– Communication cables: 1.5mm2 (AWG16)
– Test pulse outputs: 1.5mm2 (AWG16)
– Power supply: 2.5 mm2 (AWG12)
– Functional earth: 2.5 mm2 (AWG12)
}On base modules with screw terminals:
– If you use a multi-strand cable to connect the I/Os, it is recommended that you use
ferrules conforming to Parts 1 and 2 of DIN 46228, 0.14 ... 1.5mm2, Form A or C,
although this is not essential. To crimp the ferrules you can use crimp pliers (crimp
form A or C) conforming to EN 60947-1, such as the PZ 1.5 or PZ 6.5 from
Weidmüller, for example.
– Maximum torque setting: 0.8Nm
