2.2 Activating the bus termination resistor for PROFIBUS-DP
If the EU5C-SWD-DP gateway is the first or last field bus module, a bus ter-
mination resistor must be connected externally. This resistor can either be a
separate bus termination resistor or a special D-sub plug with an integrated
bus termination resistor, e.g., ZB4-209-DS2. This plug has an integrated bus
termination resistor that can be enabled and disabled.
2.3 Mounting Considerations
Install the EU5C-SWD-DP gateway in a control cabinet, a panelboard, or an
enclosure in such a way that the power supply and terminal connections can-
not be touched accidentally during operation. Snap the device onto an IEC/
EN 60715 top-hat rail or fix it in place using fixing brackets. EU5C-SWD-DP
gateways can be mounted either vertically or horizontally.
For ease of wiring, leave a clearance of at least 3 cm between the device ter-
minals and the wall or adjacent devices.
