Important Notices & Maintenance

Make sure if the voltage is correct before wiring.
Power off before distribution or for maintenance purpose.
Lock tight the casting and conduit entrance after power distribution to prevent from dusting or water spoiling.
The angle of electric actuators must not be below the horizon or stands upside down.
When electric actuators need two sets of unit for simultaneously, please connect with the individual cable.
Don’t install in complete vacuum space directly.
Actuator 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.
