Package List: 1 x Surge Protector Note: 1. The indicator window of the module is green (normal). When the module is deteriorated, the indicator window turns red and must be replaced in time2. The surge protector can be equipped with (for FS) remote remote signal alarm. The remote signal contact has one normally open and one normally closed. If one or more modules of the surge protector fail, the contact will be closed and a fault alarm signal will be sent. Indicates that the module is faulty and must be replaced3. Frequently check the air switch or fuse connected in series on the line
