(1) “Applied Rating” refers to the motor that will be connected to the drive. For example, a “D022” drive can be used in Normal Duty mode on a 15 Hp motor, or in Heavy-duty mode on a 10 Hp motor. A “D014” drive can be used in Heavy-duty mode on a 7.5 Hp motor with
the same ratings as a “D011.” The drive can be programmed for either mode. Wiring and fuses can be sized based on the programmed mode. For any given drive catalog number, Normal Duty mode provides higher continuous current but smaller overload current that is
compared to Heavy-duty mode. See parameter 306 [Duty Rating].
(2) Enclosure codes F, N, and R only. See Frame/Rating Cross-reference in PowerFlex 750-Series AC Drives Technical Data, publication 750-TD001
, for frame sizes of other enclosure types.
(3) This drive is the next larger frame size.
(4) Minimum protection device size is the lowest rated device that supplies maximum protection without nuisance tripping.
(5) Maximum protection device size is the highest rated device that supplies drive protection. For US NEC, minimum size is 125% of motor FLA. Ratings that are shown are maximum.
(6) Circuit Breaker – inverse time breaker. For US NEC, minimum size is 125% of motor FLA. Ratings that are shown are maximum.
(7) When using a circuit breaker or time-delay fuse with a drive installed in a ventilated enclosure, the enclosure volume must be greater than or equal to the minimum volume specified in this column. Application-specific thermal considerations can require a larger
enclosure.
(8) Recommended Motor circuit protector – Instantaneous trip circuit breaker. Set the trip setting to the input current of the drive and size for the continuous current of the system.
(9) For Bulletin 140M with adjustable current range, set the current trip to the minimum range that the device will not trip.
(10) Manual Self-Protected (Type E) Combination Motor Controller, UL Listed for 480Y/277V and 600Y/347V AC Input. Not UL Listed for use on 480V or 600V Delta/Delta, corner ground, or high-resistance ground systems.
(11) Bulletin 140M must be frame C (C2E), frame D (D8E), or frame F (F8E).
(12) Bulletin 140M must be frame D (D8E) or frame F (F8E).
(13) When using a Manual Self-Protected (Type E) Combination Motor Controller, the drive must be installed in a ventilated or non-ventilated enclosure with the minimum volume that is specified in this column. Application-specific thermal considerations may require a larger
enclosure.
(14) See Fuse Certification and Test Data in PowerFlex AC Drives in Common Bus Configurations Application Guidelines, publication DRIVES-AT002
, for fuse self-certification and test data for Bussmann 170M and JKS fuses recommended for the DC bus fusing.
