Connection procedure
Note:
Before making the cable connections, check that the input of the auxiliary
voltage transformer (T10) is selected correctly according to the supply voltage.
1. Open the door of the cabinet.
2. Remove any shrouds that protect the input busbars and cable entries.
3. Lead the cables into the inside of the cubicle. It is recommended to apply 360°
grounding of the cable shields at the entry as shown below.
4. Connect the cables as follows:
• Twist the cable shields into bundles and connect to cabinet PE (ground) busbar.
Connect any separate ground conductors or cables to cabinet PE (ground)
busbar.
• Connect the phase conductors to the input power terminals (L1, L2, L3). For the
tightening torques, see chapter
Technical data
.
5. Provide support for the cables whenever necessary.
6. Refit all shrouds removed earlier and close the door.
