Aligning and joining the panels

Lining up the auxiliary transformer panel with lateral cable connection as an end panel
Particularities for lining up depending on the mounting direction and the position of the
auxiliary transformer panel as an end panel:
Auxiliary transformer panel as left or right end panel
• To enable working on the lateral cable connection, a wall distance of ≥ 500 mm must be
available.
Auxiliary transformer panel as right end panel
• It is recommended to line up from right to left
• Before being able to line up panels to the left, all installation work at the lateral cable
connection must have been completed.
• Lining up from left to right:
- Position the right end panel at a distance of ≥ 500 mm from the installed panels.
- Mount the cable at the lateral cable connection.
- Line up the right end panel with the existing panels.
- If work has to be executed at the lateral cable connection after lining up the right end panel,
the end panel must be removed again.
To interconnect the panels (busbar interconnection of panels) more easily, already pre-
assembled low-voltage compartments can be removed for interconnecting the panels. Low-
voltage compartments on end panels may remain mounted.
➭ Remove pre-assembled low-voltage compartments.
The first panel is on its mounting position and the others are placed at a small distance.
➭ Align the first panel laterally.
➭ Lay shims under the panels to align them in vertical and horizontal position.
➭ Carefully approach the next panel to the one that has already been aligned.
➭ Align the approached panel by means of the alignment brackets provided at the vessel. If
required, use shims to align the panel vertically and at the necessary height.
Panels that were intended for free-standing arrangement, but implemented in wall-mounting
arrangement, cannot be taken out of the switchgear assembly if the sealing strips are
mounted.
➭ Do not mount sealing strips on panels provided for wall-standing arrangement.
In case of free-standing arrangement of the switchgear, mount the sealing strips on the rear
wall of the switchgear.
➭ Mount the sealing strips on the rear wall of the switchgear. To mount the sealing strips, use
the M5x45 Torx bolts from the pressure relief duct. Take the other bolts from the
supplementary equipment.
