Lining up panels

The panel to be lined up is moved evenly by two people, if possible, using hydraulic hoisting
cylinders, hydraulic jacks or lifting jacks. A third person acts as an observer and corrects
the joining of the busbar sections and the flanges during the process.
Risk of property damages to the panel
When the panels are joined, the busbar housings, busbars, busbar supports, or other
components may be damaged.
➭ To avoid damages to the panel to be lined up, use auxiliary means such as hydraulic
equipment or lifting jacks carefully when joining the panels. Apply auxiliary means at floor
level and only at the base frame of the panel. Place boards under the points where auxiliary
means are applied.
➭ Join the panels carefully. While doing so, observe the position of the busbar supports.
➭ While working at the busbars or the busbar housings, prop up only on the frame of the
panels.
➭ Do not prop up on sensitive parts of the switchgear like gas pipes, bursting discs, shafts,
etc.
For proper busbar assembly, remove all busbar housing covers
➭ Remove all busbar housing covers from the panels before starting installation.
➭ Keep the busbar housing covers and toroidal sealing rings (O-rings) for later reuse.
➭ Apply one lifting gear each at the rear and at the front of the base frame of the panel to be
shifted. Prop the lifting gear up at the surrounding walls.
➭ Place one person in observer position at the already mounted panel. The observer must
watch the movement of the flanges and the busbars and must be able to reach the busbar
sections by hand through the assembly openings.
➭ If the flange connections are equipped with a compensator or insulating joint:
Fix the associated insulating rings / insulating washers provisionally at the flange side of the
already fixed-mounted panel.
➭ On the observer's command, push the panel to be lined up towards the already fixed-
mounted one using the lifting gear. The observer checks and corrects the approach of
the busbar sections.
➭ Continue approaching the panels until the flanges touch evenly.
➭ In case of deviations, correct the position of the panel, compensating any floor unevenness
with shims under the corners (same points as for roller pads / tubes).
