Weak current College】 【electronic equipment maintenance operation rules】.

1. live measurements prevent even the electricity, the table amount to not slip, table pen sharpened or tied on needle on the head.
2. remove the inverter will have to wait for the power DC voltage disappears after.
3. overhaul with large capacitance electronic board, first conducted for capacitance self-discharge.
4. plug the circuit board is strictly prohibited.
5. removable devices ensure that bolt, equipment parts orderly, cannot cause the bolt or parts Assembly.
6. touch sensitive element before the body to the Board to discharge, avoid direct hand contact CUVC plate and electrostatic sensitive components.
7. replace the sensitive components, electric iron must be grounded, or cut off power supply for welding.
8. check in-line fuse matches, DC wire terminals and three-phase output terminals for shorts or on land.
9. when the inverter power supply test must check the wiring is correct, that first connected to 24V power supply, debugging CUVC plate, trouble-free and then send the DC.
10. change after power-on test, the hand cannot leave the power switch, is found to be smoke, spark off, avoid failure immediately.
11. on equipment maintenance, and repair time and marked correctly.
12. the inventory tool before work, packed live, in strict accordance with the requirements of good maintenance records
