Rockwell Automation SP600 AC Drive User Manual Version 1.0 - Manual (Page 43)

Mounting the Drive 3-5
2. 5 HP or Less Drives
In addition to the conditions listed under All Drives:
• The nearest supply transformer is larger than 100 kVA or the
available short circuit (fault) current is greater than 100,000 A.
• The impedance in front of the drive is less than 0.5%.
If any or all of these conditions exist, it is recommended that the
user install a minimum amount of impedance between the drive and
the source. This impedance could come from the supply
transformer itself, the cable between the transformer and drive, or
an additional transformer or reactor.
3.1.2 Making Sure Environmental Conditions are Met
Before deciding on an installation site, consider the following
guidelines:
• Verify that NEMA 1 drives can be kept clean, cool, and dry.
• The area chosen should allow the space required for proper air
flow as defined in section 3.1.3.
• Be sure that NEMA 1 drives are away from oil, coolants, or other
airborne contaminants.
• Do not install the drive more than 3300 feet above sea level
without derating output power. For every 300 feet above 3300
feet, derate the output current 1%.
• Verify that the drive location will meet the temperature and
environmental requirements in table A.3 in Appendix A.
