Important Notices & Maintenance
1. Check for correct voltage prior to wiring.
2. Turn power off before servicing or for maintenance purpose.
3. Use sealant to seal conduit connections after wiring to prevent dusting or water contamination.
4. The angle of electric actuator installation must be between 0~180 degree. Do not install upside down or below the
horizontal.
5. When more than one electric actuator needed to operate simultaneously, please connect with the individual cables or
install the coupling board.
6. Not intended for vacuum spaces and avoid installing near explosive atmospheres.
7. Actuators should be placed at clean and dry place for storage, and protected with outer carton from being affected by
great temperature difference or serious vibration.
8. To avoid functional failure caused by statics, do not touch any components on the PCB with metal tools or bare hands.
9. Please connect the ground wire to PE inside the electric actuator.
10. The warranty period of our products is one year.
