Step 1

 Enclose the controller in a solid, impermeable plastic bag.

 Step 2

 Plastic bags should be turned upside down, and the inlets and outlets of electrical wires should also be turned upside down (to avoid being filled with rainwater).

 Step 3

 Tie the plastic bag opening with a rope, and secure the controller well (to prevent the controller from being reversed).

 Price does not include tax. Additional tax points will be added for invoicing. For details, please consult customer service.
