Insulation test
PE power contacts
release the pressure the terminal will automatically close and hold the wire
securely and permanently.
The connection between bus couplers and bus terminals is automatically
effected by latching the components together. The K-bus is responsible for
passing data and power to the electronic components of the bus terminals.
In the case of digital bus terminals, the field logic receives power via the
power contacts. Latching the components together has the effect that the
series of power contacts constitutes a continuous power track. Please refer
to the circuit diagrams of the bus terminals: some bus terminals do not loop
these power contacts through, or not completely (e.g. analog bus terminals
or 4-channel digital bus terminals). Each power input terminal interrupts the
series of power contacts and constitutes the beginning of a new track. The
bus coupler can also be used to supply power to the power contacts.
The power contact labeled ”PE” can be used as protective earth or ground.
This contactcontacts first for safety reasons and can carry short-circuit
currents of up to 125A. Note that in the interests of electromagnetic com-
patibility the PE contacts are capacitively connected to the supporting
track. This may lead to spurious results and even damage to the terminal
when you test the insulation (e.g. insulation test for breakdown using a
230V mains supply to the PE line). You should therefore disconnect the PE
line on the bus coupler while you carry out insulation tests. You can dis-
connect other power supply points for the duration of the test by drawing
the power supply terminals out from the remaining row of terminals by at
least 10mm. If you do this, there will be no need to disconnect the PE con-
nections.
The protective earth power contact (”PE”) may not be used for any other
connections.
Electrical data
DeviceNet couplers may have different configuration levels. The electrical
data specific to the fieldbus is listed in the appropriate chapter. The follo-
wing data distinguishes between the standard version and the economy
version (BK5200 and BK5210). Either version is fully compatible to the
DeviceNet, but the economy version has only a limited number of I/O
points, which is why it permits you to attach only digital inputs and outputs.
