WARNING
AC and DC are not supported as power input at the same time!
*To ensure the safety of your electrical installation, it’s essential either a Miniature Circuit Breaker (MCB) or a Residual Current operated Cicuit-breaker with Integral Overcurrent protection(RCBO) with an electrical rating of 10A that meets national safety standards has been installed before the MINI-D. An overcurrent protection device with a rated current of 3A needs to be used in the control circuit of the MINI-D.
- DC low power load wiring
- Dry contact wiring
① Applicable to devices that can be controlled via dry contact.
② To ensure compatibility with the garage door motor, please short-circuit the terminals of the motor that were originally used to connect to the wall switch ( the short-circuiting process is safe, so don’t worry). If the garage door motor operates after short-circuiting, it is compatible; if the motor does not operate, it is not compatible.
*Make sure all wires are connected correctly.
