Mounting
When mounting, observe the information in the chapter entitled Mounting rail installation [
}
17] .
1. Ensure that the system is powered down and in a safe state.
2. Install the first bus terminal block, consisting of the fieldbus coupler and the desired Bus Terminals, on
a mounting rail.
Instead of a standard End Terminal (KL9010), install an End Terminal with RJ45 socket (KL9020) as
the last terminal at the end of the first Bus Terminal block.
3. Install the first expansion terminal block, consisting of a Coupler Terminal (KL9050) and the desired
Bus Terminals, on a mounting rail [
}
13] .
Install a standard End Terminal (KL9010) as the last terminal at the end of the first expansion terminal
block.
4. Connect one RJ45 plug of an Ethernet cable into the RJ45 socket of the KL9020 of the first bus termi-
nal block until it clicks into place.
Connect the other RJ45 plug of the Ethernet cable into the RJ45 socket (labelled
IN ) of the expansion
terminal block Coupler Terminal (KL9050) until it clicks into place.
5. Install the next expansion terminal block, consisting of a Coupler Terminal (KL9050) and the desired
Bus Terminals, on a mounting rail [
}
13] .
Install a standard End Terminal (KL9010) as the last terminal at the end of this expansion terminal
block.
6. Connect one RJ45 plug of an Ethernet cable into the RJ45 socket (labelled OUT ) of the KL9020 of the
previous expansion terminal block until it clicks into place.
Connect the other RJ45 plug of the Ethernet cable into the RJ45 socket (labelled
IN ) of the KL9050 of
the added expansion terminal block until it clicks into place.
7. Repeat steps 5 and 6 in order to connect further expansion terminal blocks. A maximum of 31 expan-
sion terminal blocks can be connected.
8. Set the Function Switch [
}
16] on all Coupler Terminals (KL9050) correctly.
