A power cut does not trap a rolling shutter fitted with a Simu DMI5. The crank fitting sits in the motor head, and the owner winds the shutter open by hand with a pole and a universal joint. Somfy builds that override into every DMI5, and the 30 Nm 12 rpm version, reference 2000774, holds the middle of the wired range. Installers choose it for exterior rolling shutters and cassette awnings that need a manual path out.

The crank fitting adds length at the head end. Somfy builds the DMI5 at 24.29 in (617 mm) overall, and the 6 mm and 7 mm override fittings project past that face. Measure the shutter box before you order, then set the bracket so the crank shaft clears the guide rail and the lintel. A 27:1 reduction sits behind the fitting, so a short pole handle moves a full aluminum curtain.
Count the turns before you commit. Somfy rates the progressive end-limits at 28 turns of travel, which covers most residential shutter drops on a 60 mm tube. The compact 24 mm motor head helps in a shallow box, and a flat plate behind it keeps the head square to the tube.
Shutters and awnings the 30 Nm rating drives
Somfy lists the DMI5 for rolling shutters and awnings. 30 Nm at 12 rpm suits a shutter curtain heavy enough to need torque and short enough to stay inside 28 turns of travel. 12 rpm is the slower speed in this part of the DMI5 range, and a slower motor keeps an aluminum curtain quiet in the guide rails.
Torque sizing on a shutter comes from curtain weight, drum diameter and rail friction. Run those numbers against the shutter drawing rather than against window size. Installers who need more head room step up to the 35 Nm or 40 Nm DMI5. Lighter curtains run on the 20 Nm version at the same 120V supply.

Specifications verified against Somfy's published reference for 2000774.
Tube fit, crowns and drives
Somfy's accessory list for 2000774 reaches across the T5 and LT50 crown and drive range, so the motor fits octagonal and round shutter tube. A 70 mm octagonal tube takes the T5/T6 70mm Octagonal Aluminum Drive (9011878). A 60 mm octagonal tube takes the 2.5 inch octagonal crown 9707025 with the 60 mm octagonal drive 9751001.
Round tube work splits by diameter. Somfy lists hard clip and soft clip drives for 2 inch round tube, the 60 mm round crown 9707026 for 2.5 inch round tube, the SM65 63 mm round set for shutter drums at that size, and the DS 78 mm and 85 mm Simbac sets for the largest drums. Order the crown and the drive as a pair. The crown carries the motor nose inside the tube and the drive passes torque to the wall, and a mismatched pair slips under load. Add the Drive Stop and Screw 9910004 to lock the drive against the tube.
Brackets and the override shaft
The DMI head mounts on a plate rather than a clip. Somfy lists the 1-piece round adjustable cast plate 9420647, the 100mm x 100mm plate 9706034, the 2-piece inside mount adjustable U 2005701 and the 2-piece inside mount 9520074 for this reference. Pick the plate from the box geometry. A flat box face takes the 1-Piece Round Adjustable Cast Plate (9420647). A deep box with a rear mounting surface takes the 2-Piece Inside Mount Adjustable U (2005701).

The crank side needs a shaft. Somfy lists the Extension Shaft 7mm Hex L=330mm with Screw (9420659) and the 220 mm version 9420657 for the DMI5, plus the 7 mm hex to 8 mm square universal joint 2005416 where a crank pole meets the shaft at an angle. Measure from the override fitting to the inside face of the window reveal before you order a shaft length. A shaft cut short leaves the eye above the reach of a hand crank.
Wiring, limits and first run
120V/60Hz AC feeds the DMI5 through an 8.2 ft 4-wire cable. Wire it to a momentary wired switch across line, neutral, up and down. The DMI5 carries no radio receiver, so a Somfy RTS handheld does nothing on this motor on its own. Owners who want remote control wire a Somfy RTS receiver ahead of the motor, and a Somfy dealer matches that receiver to the 1.5 A draw.
Set the limits at the head. The DMI5 uses progressive mechanical end-limits with 28 turns of capacity, adjusted at the motor face with the limit tool. Drive the curtain to the closed position and set the stop there, then run it open and set the second stop. IP 44 protection and Class I insulation suit an exterior shutter box. Check the cable gland and the box drainage against local code before you close the box, and leave the crank eye reachable from inside the room.
Order the DMI5 30Nm and the parts around it
Shade Motors Direct stocks the Somfy Simu DMI5 30Nm 12rpm 120V (2000774) with the parts Somfy names for the reference. Order the motor with a bracket plate, a crown and drive set matched to the tube, an override shaft that reaches the window reveal, and a drive stop to lock the drive.
Somfy's own accessory list for 2000774 includes the 1-Piece Round Adjustable Cast Plate (9420647), the 2-Piece Inside Mount Adjustable U (2005701), the T5/T6 70mm Octagonal Aluminum Drive (9011878) for a 70 mm octagonal tube and the Extension Shaft 7mm Hex L=330mm (9420659) for the crank side. The 5 year Somfy warranty covers the motor.
Frequently asked questions
Does the Simu DMI5 30Nm work with a Somfy RTS remote?
Not on its own. The DMI5 is a wired motor with no built in radio receiver, and it takes its commands from a momentary wired switch. Add a Somfy RTS receiver upstream of the motor and a handheld then drives it. Match the receiver to the 1.5 A rated current of the motor.
What tube does the Simu DMI5 30Nm fit?
Somfy lists crowns and drives for this reference across 60 mm and 70 mm octagonal tube, 2 inch and 2.5 inch round tube, SM65 63 mm round, DS 78 mm and 85 mm Simbac round. Measure the tube inside diameter and the profile, then order the crown and drive as a matched pair.
How much travel does the manual override give?
Somfy rates the DMI5 progressive end-limits at 28 turns of tube travel. A 27:1 reduction behind the 6 mm and 7 mm crank fittings lets one person wind a loaded aluminum curtain by hand. Count the turns your shutter drop needs on the chosen tube diameter before you order.
Where can the DMI5 30Nm be installed?
Somfy rates the motor IP 44 with Class I insulation and an operating range of -4°F to 158°F, which suits an exterior rolling shutter box or an awning cassette. Keep the cable gland sealed and the box drained. Mount the crank eye where someone inside the room can reach it.
