The work environment
1.0 - (40 ℃), the relative humidity of < 70%;
2. Altitude: no more than 2500 meters;
3. Avoid exposure to rain, moisture, high temperature, high heat or direct sunlight. The distance between the cooling vent and the surrounding object should be no less than 40cm.
4. Prevent working in corrosive liquid, gas, dust, conductive fiber or places with more metal fine particles;
5. Prevent working in the place of vibration or electromagnetic interference;
6. Avoid long-term upside-down storage and transportation, and avoid strong impact.
Connection mode
1. The "input" and "output" terminals of the short-connection transformer are used to test the insulation resistance of the transformer and the ground wire with a megohm meter. The resistance value of 1000V megohm meter is greater than 2M ohm.
2. The cross-section distribution of the input and output power line of the transformer shall meet the requirements of its current value; According to 2-2.5A/min2 current density configuration is appropriate.
3, input, output, three-phase power supply cord shall be in accordance with the transformer wiring board bus bar color yellow, green, and red respectively by A, B, C phase, the zero line should connect with transformer transformer neutral zero line, ground wire, the center of the shell and transformer connected. Usually we say that the ground is from transformer neutral point and the zero line of. (if the transformer has a box, it shall be connected with the box body ground line logo).
Check the input and output lines to make sure they are correct.
4. Start with no-load power connection and observe that the input and output voltage meet the requirements. Simultaneous observation machine
If there is abnormal phenomenon such as abnormal sound, fire, odor, etc., if there is any abnormality, please immediately disconnect the input power.
5. Only when the no-load test is complete and normal can the load be connected.
