5.4 Screwing the transport units together
NOTICE
Material damage caused by mechanical pressure on components
Stress that occurs during transport may exert mechanical pressure on the components.
Material damage can result.
● Line the cabinets up precisely with each other in order to avoid shearing forces when the
base units are screwed together.
● Install the converter only on a level and horizontal surface.
5.5 Connect to the foundation
Four holes for M12 screws are provided on each cabinet panel to secure the cabinet to the
foundation. Information on mounting holes and their fixing dimensions are specified in the
dimension drawing.
Install the transport units in accordance with the specifications provided in the accompanying
dimension drawings. When doing this, maintain the specified distance between the top of the
cabinet and the ceiling.
