1. After the UPS power supply is shut down, the output terminal is still powered, but the UPS power supply does not play a role at this time, and it is in a bypass state.
2. The UPS power supply will not be powered off after it is shut down, because the UPS power supply will go bypass after the shutdown, there is still a mains input at this time, so that the UPS power supply is all powered off and the UPS power supply input switch can be turned off directly.
3. The battery in the UPS should be floated up when the mains power is normal to ensure that the battery capacity is sufficient, and it can be quickly put into operation of the inverter when the mains power is blocked, so as to ensure that the computer will not be shut down suddenly. Therefore, a complete disconnection of the power supply is not advocated, which may result in a loss of battery power.
UPS power supply complete shutdown method:
1. After the switch of the panel is turned off, the panel screen shows UPSOFF, but the bypass is still energized, the machine is still hot, and the fan is spinning wildly.
2. At this time, the input of the mains power can be directly blocked, but such a blockade will cause the load equipment to be unable to have power input, and it will not be able to operate. This completely closed words do not advocate, generally after the personal computer is shut down, the mains input of the UPS power supply can also be closed, most of the occasions are not closed.
It is no problem to cut off the power when you need to pay attention, but the UPS should also be completely closed to avoid no-load power consumption.
Another point is that if the UPS power supply used by the personal computer needs to be shut down, it is recommended to shut down the computer first, let the UPS uninterruptible power supply wait for ten minutes, and let the heat in the uninterruptible power supply equipment be exhausted, and then carry out the operation method of correct shutdown.

Schneider circuit breaker maintenance method
1. Insist that the air is moist or unclean, and the pipes are not clean, which may have the following consequences:
(1) The wet gas is decomposed into mixed gases such as hydrogen and oxygen under the effect of arcing, destroying the insulation between the fractures after the main contact is broken, which is difficult to arc or arc re-ignition, and in severe cases, arc extinguishing will be formed.
