Protective Features
Motor Protection:
I2t overload protection - 150% for 60 secs, 200% fo
r 3 secs (provides class 10 protection)
Overcurrent: 200% hardware limit, 300% instantaneous fault
100-120VAC Input -- Trip occurs at 405VDC bus volta
ge (equivalent to 150VAC incoming line)
200-240VAC Input -- Trip occurs at 405VDC bus volta
ge (equivalent to 290VAC incoming line)
380-480VAC Input -- Trip occurs at 810VDC bus volta
ge (equivalent to 575VAC incoming line)
Over Voltage:
460-600VAC Input -- Trip occurs at 1005VDC bus volt
age (equivalent to 711VAC incoming line)
100-120VAC Input -- Trip occurs at 210VDC bus volta
ge (equivalent to 75VAC incoming line)
200-240VAC Input -- Trip occurs at 210VDC bus volta
ge (equivalent to 150VAC incoming line)
380-480VAC Input -- Trip occurs at 390VDC bus volta
ge (equivalent to 275VAC incoming line)
Under Voltage:
460-600VAC Input -- If P042 = 1 "High Voltage" trip
occurs at 487VDC bus voltage (344 VAC incoming
line); If P042 = 0 "Low Voltage" trip occurs at 390
VDC bus voltage (275VAC incoming line)
Controller Ride Through: Minimum ride through is 0.5 secs, typical value is
2 secs.
Faultless Power Ride Through:
100 milliseconds

Ambient Operating Temperature:
NEMA type 1 (IP20)
-10 to 40 degrees Celsius (14 to
104 degrees Fahrenheit)
Atmosphere: NEMA type 1 (IP20)
Important: Controller must not be installed in an area where the ambient
atmosphere contains volatile or corrosive gas, vapo
rs, or dust. If the controller
is not going to be installed for a period of time, it must be stored in an area
where it will not be exposed to a corrosive atmosph
ere.
Relative Humidity:
0 to 95% non-condensing
