7.15.1 Lining up panels with busbar coupling
Panel interconnection is done via busbar couplings which compensate tolerances between
adjacent panels by means of spherical fixed contacts and movable contact couplings.

Preparation
NOTICE
Reusing components
Reused components may be damaged and can damage the switchgear during operation.
⇨ Use only new original components.
NOTICE
Damage to the busbar bushes
Removing the protective caps with pointed or sharp-edged objects can damage the busbar
bushes and cause an internal arc during operation.
⇨ Do not remove the protective caps using pointed or sharp-edges objects.
Protective caps are mounted on the busbar bushes at the factory as transport protection.
Do not
use the protective caps as surge-proof caps.
1. Remove the protective caps
1
from the busbar bushes on both panels by hand.
2. If they have not been pre-assembled at the factory, hook the tension springs for earthing
2
into the clamping plate in the left-hand panel.
