4.8.1.1 Feedback of the Enable Switch
The feedback of the Enable switch can be queried via the terminals (-X6.1-2).
Cable requirements:
• Connection lines of the feedback, conductor cross-section 1 mm
2
Procedure:
1. Connect the connecting lines between the terminals (-X6.1-2) (Figure 98).
4.8.1.2 External Disconnecting Device
An external disconnecting device can be integrated into the Enable circuit (Figure 98).
Cable requirements:
• Connection lines of the coupling relay, conductor cross-section 1 mm
2
Required material (not included in scope of delivery):
• Coupling relay
Procedure:
1. Remove the jumper of terminals (-X6.3-4).
2. Mount the coupling relay in Section +C1 (Figure 99, Pos. 1).
3. Connect a disconnecting device between the terminals (-X6.3-4) (Figure 99).
4.9 Connecting of MV Skid Interfaces
4.9.1 MV Skid monitored by the APS
NOTICE: This section shows the typical connection of the MV components. Depending
on the type of the MV components, the connections may differ. In case of a specific
customer connection, a wiring diagram will be provided separately.
Terminal strips (-X8.2) and (-X10.2) are in:
• Section (+C3) (valid for 1-2 APUs) or
• Section (+C6) (valid for 3-4 APUs).
Procedure:
1. Route signal cables through the side opening and connect them to provided
terminals (Figure 100).
