How to connect the wires to a Drutex roller shutter? Diagram and doubts

The discussion addresses wiring a Drutex roller shutter with five wires and clarifies confusion about the provided wiring diagram. The blue wire is designated as live (phase), and the grey wire corresponds to neutral (zero). The black and brown wires are intended for manual control switches (up and down), which are tactile buttons; however, in the case of remote control operation only, these wires should remain insulated and unconnected. The remote control communicates wirelessly with the actuator, which contains an internal radio module that manages the shutter movement by shorting the black or brown wires internally. It is emphasized that connecting black and brown wires directly to neutral simultaneously can damage the actuator. Proper connection involves linking live (L) to blue, neutral (N) to grey, and grounding the protective earth (PE). The black and brown wires are only used if manual switch control is present. The original manual excerpt provided by the user is suspected to be unofficial or altered, lacking manufacturer markings and containing non-standard wire color designations. A reliable manual from the INEL website is recommended for accurate wiring instructions. The user later confirms a successful connection by matching wire colors (brown to brown, blue to blue, green/yellow to ground) and insulating black and grey wires, resulting in correct operation. The discussion highlights the importance of following official documentation and understanding the actuator's internal radio control mechanism to avoid wiring errors and potential damage.
