Assembling the panels
110-0084.9 / 15 NXAIR / ≤ 40 kA 55
INFORMATION
Hereafter, the disassembly of those parts is described, which are later assembled
again at the same place.
Store disassembled parts and connecting elements carefully, and keep
them ready for later reuse.
Busbar compartment is accessible either through the switching-device compartment or through
the side of the panel.
Removing the transverse partition
For panels with transverse partition, the transverse partition plate with the bushings is pre-assembled at
the factory. If the busbars are mounted from the side, the transverse partition plate must be removed.
The bushings remain in the transverse partition plate.
Remove the transverse partition plate from the busbar compartment at the upper and lower
edges together with connecting elements (1), (3) and store both for later use.
