"UniVert 2" inverter
Switches S3.7 and S3.8: number of redundant INVs
| S3.7 | S3.8 |
|
|
|
0 INVs | 0 | 0 |
|
|
|
1 INV | 0 | 1 |
|
|
|
2 INVs | 1 | 0 |
|
|
|
3 INVs | 1 | 1 |
|
|
|
The settings must be the same on all INVs and the SBS!
Standard setting: S3.7 and S3.8 open
Switches S3.4 and S3.5: not used
Switch S3.6: Switchover with gap (yes/no)
Standard setting: switchover not with gap - S3.6 open
i.e. in the event of phase deviations between INV and SBS, the SBS blocks.
If switchover with gap is selected (- S3.6 closed), the SBS does not block in the event of a phase deviation (see chapter 4.12).
