Electrical connection of the prime conductor

DANGER
High-voltage – danger to life
Test the vacuum circuit-breaker module in the switchbay with high-voltage
applied only after faultless functioning has been ascertained (see "Commission-
ing" on page 43).
Note
Grease the mating contacts with contact grease prior to mounting.
The main current path is automatically closed by the tulip contacts (21.) when the
withdrawable part withdraws.
For this there must be mating contacts in the switchbay that do not deviate by more
than ±2 mm from the nominal dimensions.
The mating contacts can be purchased from the Siemens Service Center.
