3. DRIVE (CDM) DESIGN
• Ensure that access to rotating arts of fans is prevented.
• Air used to cool the product is unfiltered. Air ejected from the product may contain foreign particles. Air
outlets should be arranged to deflect the air away from the eyes.
• The combined audible noise emitted by fans in an installation can be greater than 70 dB(A), dependent on
the air flow path.
Measure the audible noise in the installation.
When the audible noise level exceeds 70 dB(A), appropriate warning notices should be displayed.
3.1 INTRODUCTION
This section is aimed primarily at the designer of the ‘Complete Drive Module’ (CDM). The design requires
detailed Engineering knowledge and circuit design experience. The data given here cannot replace that
knowledge, but is intended to give additional information for particular requirements for the MV3000 DELTA
products.
Design data for other parts of the Power drive system can be found in Section 4: PDS Design.
If the drive (CDM) has been supplied as a complete item of cubicalised equipment, then this chapter can be
ignored.
