Eaton HMX01131NA – Frequently Asked Questions

1) What motor sizes will the Eaton H-Max IntelliPass VFD run at 208V?
The H-Max IntelliPass drive is a 208V three-phase drive built for small motor loads. Two builds are offered: an 11 amp output on an FR4 frame (HMX01131NA) and a 17 amp output on an FR5 frame (HMX01731NA). The 11 amp version is rated 3 hp. Size the drive to the motor's full-load amps off the nameplate, not to horsepower alone, since actual FLA varies by motor design.
2) Can I mount an H-Max NEMA 1 drive outdoors or in a washdown area?
No. The H-Max IntelliPass enclosure is NEMA 1, which is indoor-only protection against incidental contact and falling dirt. It is not rated for rain, hosedown, dust-tight, or corrosive locations. For a rooftop, mechanical yard, or wet area you need a drive in a NEMA 3R, 4, or 12 enclosure instead. The circuit boards are varnished and corrosion resistant, but that protects the electronics from atmosphere, not the enclosure from water ingress.
3) What does the IntelliPass option on the H-Max actually give me over a plain drive?
IntelliPass is the bypass configuration. The keypad kit includes HOA (hand-off-auto) bypass functionality, so if the drive faults you can run the motor across the line and keep the fan or pump going until the drive is serviced. That is why this build is common on HVAC fans and pumps where the load cannot simply stop. If your application tolerates downtime on a drive fault, a non-bypass H-Max is the simpler and smaller package.
4) Will the H-Max drive handle a high-inertia load that needs dynamic braking?
Not as built. This is a no-brake-chopper configuration, so there is no provision for dumping regenerated energy into a braking resistor. It suits fans, pumps, and other loads that coast to a stop. Fast decel on a high-inertia load, or an overhauling load such as a hoist or a large centrifuge, needs a drive ordered with the brake chopper option and a resistor sized for the duty.
5) Can I use this drive to replace an older solid-state starter or an existing VFD on a 208V fan?
Yes, that is one of its intended uses. The H-Max IntelliPass is built for VFD retrofits and solid-state motor control upgrades, and it integrates into panelboards and motor control centers. Two things to confirm on a retrofit: your supply is 208V, and the motor's full-load amps fall within 11 amps for the FR4 build or 17 amps for the FR5. The NEMA 1 enclosure also means the mounting location has to be indoors and dry.
6) Do I need to add a line reactor or harmonic filter with the Eaton H-Max drive?
A DC link choke is already built in, along with integrated EMI/RFI filters, so the drive ships with harmonic and noise mitigation on board. That covers typical commercial distribution. On a job where the engineer specifies a harmonic distortion limit at the service, calculate it for the installation rather than assuming the internal choke satisfies the spec on its own.
7) Is the Eaton H-Max VFD listed for use on a code-compliant commercial project?
It is cUL Certified and CE Marked. Those are the listings carried on the H-Max IntelliPass drive, which is what an inspector or a spec reviewer normally wants to see for indoor commercial and industrial motor control work.
8) What is the difference between the FR4 and FR5 frame H-Max drives?
Frame size tracks output current and physical size. The FR4 build is the 11 amp drive; the FR5 build is the 17 amp drive. FR5 is the larger chassis, so if you are swapping up in horsepower on an existing panel or wall location, confirm you have the depth and wire-bending room before ordering the FR5. Both are the same 208V H-Max IntelliPass platform.
9) Which Eaton H-Max part number do I order for an 11 amp 208V drive?
Order HMX01131NA for the 11 amp, FR4 frame, 208V NEMA 1 IntelliPass configuration. The 17 amp FR5 version is HMX01731NA. Both carry cUL certification and CE marking.
10) Which software version does the H-Max drive ship with, and does it matter for HVAC programming?
Type A software is loaded, which is the standard application platform for setup and parameter configuration. For ordinary fan and pump speed control, PID setpoints, ramps, and min/max frequency, Type A is what you commission against. If a submittal calls out a different software type, that is a separate order code, not a field download.
11) Does the H-Max keep its clock and schedule settings through a power outage?
A battery is included to maintain the real-time clock, so time-based functions and timestamped fault logs survive a loss of power. That matters if you are using the drive's scheduling or trending to troubleshoot nuisance trips on a building system.
