Technical data of product parameters

Impermissible external voltages (especially e.g. 230 VAC to earth or L-) can be measured with PXI-4071
a multimeter. We recommend checking each connection for impermissible external voltage.When testing the external cables for insulating resistance, short-circuits and wire breaks, the
cables must be disconnected at both ends in order to avoid damaging or destroying the modules with excessive voltage.
The testing for earth faults is carried out after the disconnection of the free connectors for the
sensors and control elements. The voltage connections of the free connectors on the potential
distributors must also be disconnected. The supplies of the sensors must be disconnected as PXI-4071
well as the negative pole must be separated at the control elements.
If the negative pole is set up for earthed operation, the earth connection must be interrupted
while testing for earth faults. This also applies for the earth connection of possibly existing
earth fault testing facilities.
Any connection can be tested to earth with a resistance meter or a special testing device.In this state the system is set up for testing if individual lines or a group PXI-4071
of lines are insulated against earth, but not if two lines are insulated
against each other. Otherwise there is a risk of damage.
The guideline for test voltages and insulating resistance is IEC/EN
61131-2 or DIN VDE 0160/EN 50178.For functional testing check the equipment of the control cabinet completely with help of the
label and/or documentation printout “I/O subrack”. All free connectors of the input/output modules have to be connected to the allocated input/output racks, and the voltage connections of
the cable connectors to the allocated voltage distributors. All control elements (control devices)
must be released by the factory management or be driven without auxiliary power.We recommend marking all required switch positions etc. in copies of the data sheets of the
respective control cabinet and keeping the copies in the pocket of the cabinet door. Should
modules have to be exchanged, the necessary information will thus be immediately available.
