4.2 Supply
}The module is supplied with voltage via the head module.
}The module refreshes the periphery supply for adjacent modules on the right.
4.2.1 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 switches off if the level drops below 14 V. The periphery supply
does not switch off automatically if levels drop below the limit values. However, the red
LED flashes and a message is entered in the diagnostic log.
4.3 Energy-saving functions
The energy-saving levels are controlled by the head module and are not configurable. The
module supports the following energy-saving levels:
}Switching off the LEDs
– The LED that displays module status is switched off.
}Standby mode
– All module functions are inactive.
– The LEDs that displays module status are switched off.

6.2 Inserting and removing an electronic module
Please note:
}Backplane must be installed first.
}Electronic modules may only be plugged or unplugged if the terminal block has been re-
moved first.
}The module may only be inserted if the connection to the left-hand modules has already
been interrupted on the backplane. The procedure is described in the operating manual
"PSS u2 B1/B4" for the backplane, under "Form supply groups".
}The mechanics of the electronic modules are designed for 20 plug in/out cycles.

}Module bus communication between the other modules is not interrupted.
}The configuration data is retained.
}The module is detected automatically as soon as the module is re-inserted.
Procedure:
1. Removing an electronic module [ 13]
2. Inserting an electronic module [ 11]
A new electronic module can be inserted during operation.
Procedure:
}Inserting an electronic module [ 11]
Effects:
}Module bus communication between the other modules is not interrupted.
}To detect the new module the following steps can be necessary:
– Creating a new configuration or changing an existing configuration
– Download of the configuration to the head module
– Restart of the head module. After a restart, the system behaves as after a warm reset
using a reset pushbutton (see operating manual of the head module, chapter “Reset
pusbutton", section "Carrying out a warm reset (restart)").

7 Wiring
7.1 General wiring guidelines
Please note:
}The requirements of the supply voltages can be found under "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 8A.
}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:Art-
icle 250).
}Details of the minimum range for conductor cross sections on connection terminals can
be found in the section entitled Connection mechanism for terminal blocks [ 15].
}Use copper wiring.
7.1.1 Connection mechanism for terminal blocks
Please note:
}The minimum cable cross section for field connection terminals on the terminal blocks is
0.15mm2 (AWG26).
}The maximum cable cross section for field connection terminals on the terminal blocks is
1.5mm2 with ferrules (AWG14)
}Use copper wiring.
Procedure:
}Use a flat head screwdriver.
}Strip the wire back 9 mm.
}Feed the stripped cable as far as it will go into the opening for the spring-loaded terminal.
}Check that the cable is firmly seated.

}Too warm:
If the module temperature exceeds a threshold value, then:
– a warning is sent to the head module.
If the temperature drops back below the threshold value, the module sends an all-clear.
}Too hot:
If the module temperature exceeds another threshold value, then:
– an error message is sent to the head module
After the "too hot" message has been received, if the temperature drops back below the
"too warm" threshold value, the module will switch to an error-free state.
}Messages about a missing periphery supply can be suppressed through the configura-
tion.
