TEMPERATURE MEASUREMENTS
Temperature measurements should be made at the points shown Figure 3 to ensure that the
maximum values are not exceeded under any circumstances. Forced air cooling may be required in
order to achieve this.
Figure 3 Temperature Measurement Points
Figure 3 defines where measurements should be made to determine module and casting
temperatures, top side and bottom side (the difference between the two points is defined as the
delta). There must be sufficient air flow through the drive so as not to exceed the casting and
module temperature limits.

During file start up and seeking, 12 volt ripple is generated by the file (referred to as dynamic
loading). If several files have their power daisy chained together then the power supply ripple
plus other file's dynamic loading must remain within the regulation tolerance window of +/- 5%.
A common supply with separate power leads to each file is a more desirable method of power
distribution.
