5. Locate the 96-way connector on the PROFIBUS board into the
socket (A) at the back of the control board, as shown in
Figure 3-9. Secure the front panel to the chassis using the two
M4 screws removed at step 3.
6. Attach the label (F) if supplied, and fit dust covers (B) to any
PROFIBUS connector that will be exposed for a lengthy period,
see Figure 3-9.
7. Re-fit the cover plate over the control board, using the five
screws and the M5 nut and washers removed at step 2.
3.7 Connections
CAUTION
This equipment contains solid-state devices that may be
affected by electrostatic discharge. Observe static handling
precautions.
Connections to the PROFIBUS board must use 9 way D-type
PROFIBUS connectors fitted with 440UNC screwjacks.
3.7.1 External
Wiring
It is important to strain relieve the PROFIBUS cable before it is
connected to the drive. Strain relief helps to prevent damage to the
PROFIBUS connection or the cable being unexpectedly unplugged.
Electrical noise and electromagnetic interference can be introduced
into a microelectronics system via the cables and wires connected
to it. To avoid this, wiring which could carry noise, that is ‘dirty’
cables, should be kept away from cables that are to be kept free
from electrical noise or ‘clean’. Wiring that falls into the same group
can be run together, while wiring from different groups should be
kept apart, though paths may cross at right angles. All connections
to the PROFIBUS board are considered to be clean.
3.7.2 PROFIBUS
Connectors
The PROFIBUS board contains 1 external connection, a 9 way D-
type female connector that is used to connect to the PROFIBUS
network cable.
