• The ACS850-04 is an IP20 (UL open type)
drive to be used in a heated, indoor
controlled environment. The drive must be
installed in clean air according to enclosure
classification. Cooling air must be clean, free
from corrosive materials and electrically
conductive dust. See the Hardware Manual
for detailed specifications.
• The maximum ambient air temperature is
40 °C (104 °F) at rated current. The current
is derated for 40 to 55 °C (104 to 131 °F).
• The drive is suitable for use in a circuit
capable of delivering not more than 100,000
rms symmetrical amperes, 500 V maximum.
• The cables located within the motor circuit
must be rated for at least 75 °C (167 °F) in
UL-compliant installations.
• The input cable must be protected with fuses
or circuit breakers. Suitable IEC (class gG)
and UL (class T) fuses are listed in the
Technical data section of the Hardware
Manual. For suitable circuit breakers, contact
