601/604/607 US Supplement
For IP 54 enclosures with Normal Use:
Below +40
°
C: Locate the pertinent drive type code in the Derate
Table to determine the curve number to apply. Find the ambient
temperature at the bottom of the Derate Curves. Follow this
temperature up vertically to where it meets the applicable curve
number. From the point of intersection read across horizontally to
determine the appropriate percent derate. The current rating equals
the I
2N
current from the Drive Output Ratings table times the percent
derate.
Above +40
°
C: Calculate the I
2N
current derate (if any) at 40
°
C
per the IP 54 Normal Use, Below +40
°
C instructions immediately
above. Starting from this current level decrease the current rating an
additional 3.5% of I
2N
for each 1
°
C above 40
°
C.
For IP 54 enclosures with Heavy Duty Use:
Below +40
°
C: Use the I
2HD
current rating given in the Drive
Output Ratings table. No derating is required.
Above +40
°
C: Calculate a tentative derated current per the IP 54
Normal Use, Above +40
°
C instructions above. Compare this
calculated value with the I
2HD
current given in the Drive Output
Ratings table. The current rating equals the smaller of I
2HD
from the
Drive Output Ratings table or the calculated derated current.
ACx 607 Drives
Maximum temperature in all cases should not exceed 50
°
C.
For IP 21/22 enclosures with Normal Use:
Below +40
°
C: Use the I
2N
current rating given in the Drive Output
Ratings table. No derating is required.
Above +40
°
C: Decrease I
2N
by 1.5% for every 1
°
C above
40
°
C.
For IP 21/22 enclosures with Heavy Duty Use:
Below +40
°
C: Use the I
2HD
current rating given in the Drive
Output Ratings table. No derating is required.
Above +40
°
C: Use the I
2HD
current rating given in the Drive
Output Ratings table. No derating is required.
For IP 54 enclosures with Normal Use:
Below +40
°
C: Use the I
2N
current rating given in the Drive Output
Ratings table. No derating is required.
Above +40
°
C: Decrease I
2N
by 1.5% for every 1
°
C above
40
°
C.
For IP 54 enclosures with Heavy Duty Use:
Below +40
°
C: Use the I
2HD
current rating given in the Drive
Output Ratings table. No derating is required.
Above +40

C: Use the I
2HD
current rating given in the Drive
