SMA CLUSTER CONTROLLER Installation - Manual (Page 52)

Procedure:
1. Connect the connection cable to the sensor (see the manual from manufacturer). Trim the
unneeded insulated conductors up to the cable shield and note down the conductor colors.
2. Connect the connection cable to the eight-pole plug:
• Unlock conductor entry 8 with a screwdriver and insert the insulated conductor of the
wire into the conductor entry.
• Unlock conductor entries 5 and 7 with a screwdriver and insert the insulated conductors
of the connection cable into the conductor entries. Observe the pin assignment.
3. Insert the eight-pole plug into pin row B in terminal X8.
4. On the connection cable, mark the terminal and the pin row to which the connection cable is
assigned. Use the supplied cable tie with caption field.
5. Write down the terminal assignment on the supplied supplementary sheet.
6.12 Connections for Grid Management Services
6.12.1 Options for Implementing Grid Management Service
Setpoints
You can have the Cluster Controller implement the grid management service setpoints by using
open-loop or closed-loop control.
In the event that the Cluster Controller evaluates a setpoint as invalid or does not receive a setpoint
within a configurable interval, you can make additional settings for the fallback.
Configure the grid management services via the Cluster Controller user interface (see the
Cluster Controller user manual).
Open-loop control
For Cluster Controller systems without self-consumption and with direct limitation of active power
feed-in, the operating mode Open-loop control is used. In this operating mode, the
Cluster Controller can receive the grid management service setpoints from three different types of
signal source. The different types of signal source can be combined so that, for example, the
setpoints for the active power limitation can be received as digital signals and the reactive power
setpoints can be received as analog signals:
Type of setpoint signal Explanation
Digital signals The setpoints are transmitted to the Cluster Controller as
digital signals in the form of binary values. Up to four re-
lay contacts can be used for the active power limitation
and the reactive power setpoint.
