Commissioning without function test
Putting defective switchgear into operation can cause life-endangering injury due to an
internal arc.
⇨ Execute a mechanical function test and test operation successfully before
commissioning. Never put switchgear into operation if a part of it does not work as
described.
⇨ If faults cannot be cleared on site, do not put the switchgear into operation, and contact
the Siemens Service Hotline.
Sharp-edged sheets
If covers have to be removed from the switchgear, sharp-edged sheets inside the switchgear
can cause cuts. Sharp-edged sheets inside the switchgear can damage cables.
⇨ Wear personal protective equipment (e.g. cut-resistant gloves and arm sleeves).
⇨ When working inside the switchgear, it must be observed that cables do not touch any
sharp-edged sheets. Cover sharp-edged spots, if required.
1. Check the data on the rating plate and the auxiliary voltage of the control and end devices
against the requirements.
2. Check service readiness [▶ Page 135, "Ready-for-service indicator"].
3. Check switchgear fixing.
4. Check connection to substation earth.
5. Check connection of all earthing connections.
6. Check earthing of cable terminations on all connected high-voltage cables.
7. If intended by the customer, perform cable test [▶ Page 163, "Cable testing"].
8. On all feeders without connected high-voltage cables, switch the switching devices to
EARTHED position and lock them, or close all bushings in a surge-proof way.
9. Check the tightening torques of the bolted joints of the low-voltage equipment at random.
10. Check all switchgear parts that have been disassembled and assembled again on site during
installation, or that have been installed subsequently, in order to verify correct assembly and
completeness.
11. Check the wiring of all auxiliary wire connections against the circuit diagrams.
12. Check clamping and plug connections at random (perfect contact, labels, etc.).
13. Remove any attached instruction labels or documents that are no longer required for
operation.
14. Remove any tools, materials etc. that are no longer required from the area of switchgear.
15. Remove dirt from the area of the switchgear.
16. Fit all covers.
17. Put the covers on the capacitive test sockets.
18. Touch up scratches and impacts in the surface painting with a paint pen.
19. Check the version of the firmware installed on the protection devices, and update if required
[▶ Page 9, "IT security"].
20. Keep the following accessories ready to hand:
▪ Operating instructions
▪ Operating levers for switching the panel
▪ Circuit diagrams
