If the units are not arranged directly horizontally, you will need a longer
cable for the connection of the X1 terminals:

Arranging the units vertically
Note:
With a combined unit arrangement, it is absolutely necessary
that between the two rows of drive units a baffle is mounted, in
order to prevent the blowers of the upper row from sucking in
the warm air of the bottom row.
CAUTION
Property damages due to overheated units!
⇒
Mount a baffle between the two unit rows. Otherwise
the performance data of the units can decrease and
the units can be damaged with undiminished
performance requirement.
If the units in the control cabinet are arranged vertically, you need to use
twisted single conductors for the power connection of the drive and
control systems (terminal L+, L-) instead of the supplied copper strands.
The single conductors for the power connection of the drive and control
systems may have a maximum length (twisted) of 1 m (Material number
of cable: 291 268; Length: 1,2 m).
The ground connections of units (unit rows) that are vertically arranged
must be connected by a separate cord. The minimum cross section for
this cord is 10 mm
2
.
The control voltage bus must be connected with the designed Rexroth
cable (designation: INB0647). Lay the shield of this cable to the unit
grounding bolt (terminal X12) on the supply module.
