• Always use a crimp-on terminal with flexible wiring.
• Avoid short circuits by bundling and fixing both the mains wiring and the low voltage
wiring as close to the connector as possible. See picture above.
• Compared to the mains wiring, the low voltage wiring must be double insulated. The
cross section and insulation of the mains wiring must comply with applicable local
installation regulations.
• If double crimp-on terminals are used, the sum of the currents of all the relay outputs
of the same module may not exceed 20 A.
• During maintenance work on field equipment connected to a relay output, or when
removing a connector of a relay output, always turn off the mains power supply using
an external local isolator. An open relay contact must not be considered to be a safe
separation.
Across inductive loads (such as a reed switch) use a spark extinguisher. This significantly
extends the service life of the switch contacts.
Ethernet connections
With the Ethernet connections on the controller you can connect the system to a network. The
Ethernet connections do not provide Power over Ethernet (PoE).
Connecting an Ethernet port
The shielding of the Ethernet ports is fitted externally to the shield connection on the controller. The
Shield connection is located below the Ethernet ports. In principle, this shielding does not have to
be connected, as this is coupled internally and at a high frequency (capacitive coupling) with the
functional earth (FE). The shield connection only has to be connected directly to the functional earth
(FE) if communication problems arise as a result of low-frequency electromagnetic interference.
