2.2 Mounting (continued)
2.2.2 Minimum Spacing
As shown in figure T2.2, you must maintain a
minimum spacing of 2 inches (50.8 millimeters)
from enclosure walls, wireways, adjacent equip-
ment, etc. for adequate system ventilation.
Also note that the SD4840EK drives must be
mounted in the orientation shown in the figure.
Mounting the system in any other orientation will
decrease the efficiency of the ventilation slots in
the top and bottom of each module which may
lead to system overheating and malfunction.
When installing multiple SD4840EK drives that
are all running at the full 4.0 A motor current, it is
possible for the drives to overheat. It is difficult to
calculate when this can occur because it is based
on not only the current and duty cycle of the
motor, but also such variables as enclosure size
and ambient temperature. If overheating does
occur, you have two choices. You can install a
cooling fan beneath the drives to force additional
air up through the modules or you can increase
the space between the drives to limit mutual heat-
ing.
The SD4840EK has a bit in the network data that signals when the module is close to overheating. This bit is
the Temperature_Above_90C bit, and is available in Status Word 1 of the network input data while in Com-
mand Mode. This bit is further explained in the
STATUS_word1 Format
section starting on page 76.
2.2.3 Mounting the SD4840EK Module
Mounting an SD4840EK is a very simple process thanks to the design of the enclosure.
1) Engage the top of the clip on the back of the enclosure with the top of the DIN rail
2) Rotate the module down until the metal bracket snaps on to the DIN Rail.
Once all of your drives are installed, it is strongly suggested to use the end caps from Phoenix Contact with
the part number of 271 37 80 to secure the modules on the DIN Rail. These end caps prevent the drives from
sliding along the DIN rail if it is subjected to shock or vibration during machine operation.
