2.3 Mounting at the wall
It is also possible to install the drive controller directly at the cabinet or housing
wall. It has to be installed always vertically. Verify that the circuit board is
ventilated adequately (free convection). The circuit board contains four mounting
holes and must be fixed at all four holes. Mounting distance to housing wall must
be min. 10 mm. If necessary, suitable spacing bolts must be used. The following
figure shows the fastening dimensions.

2.4 Connection/Wiring
Note also the safety and mounting notes in section 2.1.
CAUTION
•
When connecting the drive controller please note that the
programming can be application specific and therefore it
can differ from the standard programming described in this
manual. Note the appropriate drawings and wiring
diagrams!
•
The connection and wiring has to be carried out in
accordance with EMC! A maximum line length of 10 m for
the wiring may not be exceeded.
•
To avoid interferences the connected motors have to be
grounded well.
•
Connect only interference-free motors.
The connectors of the drive controller are located on two plug-in terminal strips
with screw terminals. For an easy mounting the plug-in terminal strips at the
drive controller are pluggable and can be pulled off.
The connectors are labelled appropriately. Further information to the inputs and
outputs of the drive controller can be found on page 29. The figure on page 28
shows the assignment for standard programming.
The control inputs can be operated either directly by floating contacts or via an
external PLC or other electronic switches. If the control inputs are controlled by
