| Frequency converter maintenance |
| 1, the inverter has a large electrolytic capacitor, cut off the power after the capacitor is still remaining voltage, so should be in the off power about 10min, "charging" indicator completely extinguished or confirm the positive and negative bus voltage in the following 36V to maintain the operation.
2, must be professionals to replacement parts, is strictly prohibited to thread or metal objects are left inside the inverter, otherwise it will cause damage to the device.
3, maintenance of the best record before the key parameters of the inverter.
4, after the replacement of the main control board, must be in the power of the operation before the modification, or may cause damage to related equipment.
5, in the energized state no wiring or plug connector etc..
6, do not allow the inverter output terminals (V, W, U) connected to the current power grid.
7, inverter factory has passed the pressure test, the user does not have to carry out the pressure test, otherwise it will damage the device. | | | author: Published at: 2015/6/30 17:06:22 |  |
