Connection To Digital Input X10; Digital Inputs X10 - SMA DATA MANAGER M Operating Manual

6 Connection
Procedure:
1. Connect the connection cable to the RS485 device (see the manual from manufacturer).
2. Remove the sheath from the connection cable.
3. Fold the surplus cable shield back over the cable sheath.
4. Strip the insulation off the wires.
5. Connect the connection cable to the supplied 6-pole
connector. Ensure that the conductors are plugged
completely into the terminal points up to their
insulation.
6. If the product is at the beginning or end of the
RS485 bus, install a jumper wire as a line terminator
between pin 5 and pin 6 on the six-pole connector.
7. Plug the 6-pole connector into the socket X9 on the product. Observe the pin assignment.
8. Ensure that the connector is securely in place.
9. Ensure that all conductors are correctly connected.
10. Ensure that the conductors sit securely in the terminal points.
11. Fit the cable shield onto an external shielding clamp.

6.10 Connection to digital input X10

6.10.1 Digital inputs X10

External signal sources with potential-free switching contacts can be connected to the six digital
inputs X10 (e.g., for active power limitation). You can use ripple control receivers or remote
terminal units, for example, as external signal sources.
In a system with multiple SMA Data Managers, the external signal sources must be connected to
the digital inputs of the System Manager.
