1,To protect the safety of the equipment and user, please read the manual carefully before doing the test, and operate according to the manual.
2,The power supply of equipment: AC A, B, C, N. The A, N provide power supply for the control unit, and B, C provide power for the regulator.
3,To ensure safety, the equipment has protective earth terminals, ensure connect the test transformer and controller are connected to earth.
4,To ensure the sampling is exact, please ensure the earthing terminals of the test transformer and controller are connected to the grounding grid, and make sure the two earthing terminals are connected to the same grounding grid; the earthing continuity value is less than 0.1.
5,During the testing, the user should keep a safe distance for safety( less than 20KV per meter in air)
6,Measure the insulation resistance for the transformer before testing. The insulation resistance value between input to ground should be more than 2M, and it should be more than 10M between output to ground.
7,Check if the contacts on each component are loose, and if the connection is well, if each protection system works normally.
8,Please discharge for high voltage end after finishing the test. Store the equipment in a dry, ventilated place.
9,The working and storage places of this device should be free from gases, vapors, chemical dust,t and other explosive and corrosive media that seriously affect insulation.
10,This device must be operated by professionals, and the operating procedures must be strictly followed
