4. Installation
Proper installation is crucial for the safe and efficient operation of your tubular motor. If you are unsure about any steps, please consult a qualified electrician or installer.
4.1 Pre-installation Checklist
- Ensure the power supply is disconnected before starting any electrical work.
- Verify that the motor's crown and driver are compatible with your roller blind's driving tube (e.g., 50mm, 55mm, 65mm, 70mm). The standard package includes components for a 55mm tube.
- Have the necessary mounting brackets and idler set ready. These are typically purchased separately.
- Confirm the remote controller (RF433mhz) is available for initial setup and operation.

4.2 Assembly Steps
- Prepare the Driving Tube: Insert the tubular motor into the driving tube (e.g., 55mm grooved tube). Ensure the crown and driver are correctly seated and engaged with the tube's internal grooves.
- Mount Brackets: Securely attach the one-pair bracket to the wall or ceiling where the roller blind will be installed. Ensure the brackets are level and spaced correctly to support the driving tube.
- Install Motor and Tail Plug: Place the motor end of the driving tube onto one bracket. Insert the tail plug into the opposite end of the driving tube and secure it to the other bracket.
- Attach Fabric: Connect the blind fabric to the driving tube.
- Wiring: Connect the motor's electrical wiring to your power supply according to local electrical codes. Refer to Figure 4.2 for a general wiring overview. It is recommended to have this step performed by a qualified electrician.



5. Operation
The A-OK AM45-20/17-MEL-PZ motor supports both RF433 remote control and Tuya Zigbee smart home integration.
5.1 Remote Control (RF433mhz)
To operate the motor using an A-OK RF433mhz remote controller:
- Pairing: Follow the specific pairing instructions provided with your A-OK RF433mhz remote controller. This typically involves a sequence of button presses on the remote and a brief power cycle of the motor.
- Basic Functions:
- UP/OPEN: Press the 'Up' button to raise the blind/awning.
- DOWN/CLOSE: Press the 'Down' button to lower the blind/awning.
- STOP/MY: Press the 'Stop' or 'My' button to halt the movement at any desired position.
- Setting Limits: Refer to your remote controller's manual for instructions on setting the upper and lower travel limits of the blind/awning. This is essential for preventing damage to the motor and the blind system.

5.2 Tuya Zigbee Smart Control
For smart home integration, the motor can be connected to a Tuya Zigbee gateway (sold separately).
- Gateway Setup: Ensure your Tuya Zigbee gateway is set up and connected to your home network according to its own instructions.
- Adding Device: Put the motor into pairing mode (refer to the motor's specific instructions for this, often a button press or power cycle sequence). Open the Tuya Smart app, select your Zigbee gateway, and initiate the device search.
- App Control: Once paired, you can control the motor (open, close, stop, set percentages) via the Tuya Smart app. You can also integrate it into scenes, schedules, and voice control systems (e.g., Amazon Alexa, Google Assistant) if supported by your Tuya setup.
6. Maintenance
The A-OK AM45-20/17-MEL-PZ tubular motor is designed for low maintenance. However, regular checks can help ensure its longevity and optimal performance.
