Installation matters
1.Instructions for breaking away from failure
When the surge protector is overheated or broken down due to deterioration, the failure release device can automatically disconnect it from the grid, and red (window) signals (a normal window display for the green), which suggests that the protector has failure need to be replaced immediately.
2.the remote communication alarm device
Remote communication contact for a normally open - a normally closed contact, when the failure of one or more modules, dry contact state.
