Connection Notice Diagram
NOTICE

A. Be sure to make the correct connection according to the product nameplate and the wire marking. The wrong connection will cause the damage of the product, and even result in the danger of fire and so on.

B. To ensure safety, a fuse should be connected to the input terminal to prevent permanent damage caused by wrong connection of positive and negative poles and over-voltage. Some products have been installed with a fuse before leaving the factory, and due to current reasons, you’d better match a fuse for those products without one.
