Somfy builds the Glydea ULTRA 35 in a plug version and a bare-lead version. Reference 1003153 is the bare-lead one. It arrives with a 1.5 m VVF cable, four conductors, stripped ends, ready for an electrician to land in a junction box above the track. Installers choose it for ceiling pockets, closed valances and commercial rooms where an outlet beside a drapery rail would show.
The motor pulls a Glydea ULTRA track through a toothed belt and a drive pulley. It traverses 35 kg of fabric, which works out to 77 lb of lined drapery on a straight rail. That capacity figure, not the torque number, settles whether this motor suits the panel you have drawn.
Fabric weight sets the model number
Glydea model numbers carry their capacity. A 35 handles 35 kg. A 60 handles 60. Measure the panel weight before anything else: fabric weight per yard, times the width you are gathering, plus lining and any hem weights. A 120 inch wide blackout panel in a heavy velvet closes on that 77 lb ceiling faster than most people guess, and a sheer of the same width sits nowhere near it.
Track length matters second. Somfy rates traction, and a long rail with many carriers adds rolling resistance on top of the fabric load. Keep a margin. A panel that reads 70 lb on paper belongs on a 60 rather than sitting at the top of a 35.
This motor runs 0.6 Nm at 105 rpm, and that speed is what buyers notice in a finished room. A 12 foot bi-parting pair closes in seconds. The motor holds 38 dB while it runs, quiet enough for a bedroom track above a headboard.

Two rows on that table drive the install plan. Class I means the motor needs a protective earth conductor, and the four-wire cable carries one. IP 30 keeps this motor inside, away from bathrooms with open showers and away from any rail that sees weather.
Wiring a Class I motor with stripped leads
The 1.5 m lead gives you 4.92 ft of reach from the motor head to your junction box. Plan the box position around that, because extending the run belongs to your electrician and your local code, not to a splice inside a curtain pocket. The four conductors cover line, neutral, earth and the control leg.
Power the motor before you mount the fabric. A Glydea ULTRA head sets its limits electronically, and running the belt with an empty carrier train lets you confirm the travel path without dragging 70 lb of velvet through a bad stop. Mount, wire, power, set limits, then hang.
The thermal cutout runs 7 minutes. Continuous cycling during a commissioning session will trip it, and the motor resumes after it cools. Build that pause into the schedule on a job with twenty tracks.
Track hardware, carriers and the drive pulley
A Glydea ULTRA motor arrives as a head. The rail, the belt and the carrier train come from the same family, and the parts below are the ones a 35 kg track build needs.
The Somfy Glydea Drive Pulley (1780945) sits at the far end of the rail and returns the belt. Every motorized Glydea run carries one. Order it with the motor rather than after, because a pulley-less rail cannot be commissioned.
Carrier spacing sets the fold depth. The Somfy RippleFold 80% Carriers, 5 per ft (1780903) give the shallow wave most designers specify for a contemporary room. Fuller 100% and 120% spacings exist in the same family for deeper folds and more fabric per foot of rail, which pushes the panel weight up toward the 35 kg ceiling.
The Somfy Glydea Heavy Duty Master Carrier (1781344) clamps the belt and tows the leading edge of the panel. Heavy blackout and lined velvet earn the heavy duty version. A light sheer will run on the standard carrier.
Mounting comes down to the pocket. The Somfy Glydea One Touch Ceiling Bracket (1780907) snaps the rail up into a ceiling or a soffit and releases with a press, which saves time on a rail you will pull down for fabric cleaning. Use 35 rail components throughout. Parts cut for a 60 rail will not seat on a 35 profile.
Control and integration path
Out of the box this head answers a wired control leg. That suits a job already running low voltage or line voltage control from a panel, and it suits an integrator who wants the drapery on a contact closure from a third-party system.
Somfy publishes two add-on modules for the Glydea ULTRA platform. The Zigbee (2-Way) Module 9000043 brings the track onto a Zigbee network with two-way feedback. The RS485 (2-Way) Module puts it on a Somfy Digital Network bus alongside Sonesse motors, where one wiring run addresses many motors and reports position back. Either path lets a wired track join a TaHoma scene later without replacing the motor head.
Plan the module decision at rough-in. Pulling a data pair to the motor pocket during construction costs nothing. Pulling one through a finished ceiling costs a drywall patch.
Rooms that suit the no-plug version
Hotel rooms, conference suites and open-plan residences share a problem: the drapery track lives where no outlet belongs. Reference 1003153 answers it. The motor lands in the ceiling, the feed lands in a box, and the finished room shows a rail and fabric with no cord in sight.
Retrofits work the other way. A room with an outlet above the window and no appetite for an electrician suits the plug versions of the ULTRA 35 instead. Buy the bare-lead head when an electrician is already on the job.

Frequently asked questions
How much drapery will a Glydea ULTRA 35 pull?
Somfy rates the traction force at 35 kg, which converts to 77 lb of fabric. That covers the panel, its lining and any hem weights on the carrier train. Weigh a sample yard of the specified goods and multiply by the gathered width. Panels that land above 70 lb belong on a Glydea ULTRA 60.
Does the no-plug version need an electrician?
Reference 1003153 ships with a 1.5 m four-conductor VVF cable with stripped ends and no plug fitted. It carries a Class I earth conductor, so the connection belongs in a junction box wired to code. Position the box within 4.92 ft of the motor head before the ceiling closes.
What track hardware do I need with reference 1003153?
Every motorized Glydea run needs a drive pulley at the far end, a master carrier on the belt, the RippleFold carriers that match your fold depth, and brackets sized for the rail. Order 35 rail components. A 60 rail part will not seat on a 35 profile.
Can I add Zigbee or RS485 control later?
Yes. Somfy publishes a Zigbee (2-Way) Module 9000043 and an RS485 (2-Way) Module for Glydea ULTRA motors. Either one snaps onto the head and brings the track onto a network with two-way position feedback. Pull a data pair to the motor pocket at rough-in to keep that option open.
