Installing a Rolling Shutter Motor: Complete Walkthrough

Prerequisites

• Tubular shutter motor (size matched to shutter width and weight)
• 220V power supply at the installation point
• Shutter in good mechanical condition — no broken slats, smooth manual operation
• Step ladder, hex key set, cable clips, conduit

Step 1: Select the Correct Motor

Measure the shutter width and weigh the curtain (or estimate: steel slats weigh approx 6–8 kg per m²). Select a motor torque rating at least 30% above the calculated load. For shutters wider than 4 metres, use a motor with built-in thermal protection.

Step 2: Remove the Existing Axle Supports

Lower the shutter fully. Remove the end caps from both sides of the barrel. Slide out the axle. The tubular motor replaces the axle — it fits inside the barrel tube.

Step 3: Insert and Secure the Tubular Motor

Slide the motor into the barrel from the motor-head end (the end with the power cable exit). The motor head should protrude slightly from the barrel. Fit the anti-rotation bracket to the motor head and fix it to the shutter bracket on the wall to prevent the motor body from spinning.

Step 4: Refit the Barrel and Slats

Slide the barrel (with motor inside) back onto the support brackets. Refit the end cap on the idle side. Reconnect the shutter curtain to the barrel using the slat-to-barrel clip.

Step 5: Wire the Motor

The tubular motor cable has 3 or 5 cores. For a basic 3-wire motor: Brown = UP, Blue = DOWN, Green/Yellow = Earth. Connect to a 3-position wall switch or the receiver board if using remote control. Run all wiring in conduit and secure with cable clips every 300 mm.

Step 6: Set the Limit Switches

Most tubular motors have internal limit adjusters accessible through a port on the motor head. Power the motor and run it UP — use the UP limit adjuster to stop the barrel at the exact fully-open position. Run it DOWN and use the DOWN limit adjuster to stop precisely at the floor seal. Fine-tune until the shutter stops cleanly with no mechanical tension.

Step 7: Test and Commission

Operate the shutter 10 complete cycles. Listen for any grinding or clicking sounds from the barrel. Check that the curtain stacks evenly at the top. Verify the motor housing temperature — it should not feel hot to the touch after 5 cycles.
