Procedure:
1. Connect the connection cable to the digital signal source (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 six-pole plug:
• Depending on the digital signal source and the pin assignment in terminal
X4
, identify the
conductor entries that are required for connecting the connection cable. The voltage
supply (24 V) and the reference potential (GND) only need to be connected once for
each signal source.
• Release the required conductor entries using a screwdriver and insert the insulated
conductors into the conductor entries. Observe the pin assignment.
3. Connect the six-pole plug to terminal
X4
. Observe the pin coding.
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.
6.12.2.3 Connecting a Signal Source to a Digital Input for Reactive
Power Setpoint
Digital signals for reactive power setpoints can be transmitted to up to four pin groups at terminal
X5
on the Cluster Controller. A ripple control receiver or a remote terminal unit can be used as a
digital signal source, for example.
Additionally required material (not included in the scope of delivery):
☐ Up to four digital signal sources
☐ Connection cable (see Section 6.3 "Cable Requirements", page 28)
Requirements:
☐ The signal source must be technically suitable for connection to the digital inputs (see
☐ The connection cable must be prepared for connection to the multipole plug (see Section 6.5,
