Each unit fits in its cubicle within the vertical
section. You may need to adjust the height of a
cubicle when changing or adding units. Refer to
the following two examples as a reference when
adjusting the height of a cubicle.
To convert three 12E height (300 mm/11.8 in)
compartments to a single 36E height
compartment follow this procedure:
Disassembly
• Pull out the three withdrawable units. (See
Remove/Insert Withdrawable Units section).
• Disconnect power and control cables. Take outthe
two upper control terminal block supports (fig.
45) with their control terminal blocks (fig. 44).
• The lower support may remain unchanged or, if
necessary, can be relocated and converted to one
or two, 12-pole control terminal blocks. When
converting from two to one control terminal
blocks, the remaining one must be at the top
of the support.
• Dismantle the two middle compartment bottom
plates (fig. 48) with their guide rails (fig. 47).
The lower bottom plate remains unchanged.
