This product must be used with an explosion-proof locking joint certified by an explosion-proof inspection agency to form an explosion-proof and explosion-proof system. The product and field wiring should be shielded cables with a cross-section> 0.5mm2, and the shielding layer must be grounded. The cable should be connected to the positioner through an explosion-proof tube. When the positioner is energized (loading signal), it is strictly forbidden to open the junction box cover and the window cover. The user is not allowed to change the electrical components in the product at will.
