How to use and maintain UPS uninterruptible power supply
Uninterruptible power supply - how to extend UPS power supply time?
There are two ways to extend the power supply time of an uninterruptible power supply system:
1. External high-capacity battery pack: according to the required power supply time corresponding to the corresponding capacity of the battery pack, but be aware that this method will cause a relative increase in battery charging time, and also increase the area and maintenance costs, it is necessary to seriously evaluate The
2. Optional large capacity uninterruptible power supply system: This method not only can reduce maintenance costs, if the load equipment expansion, the larger capacity of the uninterruptible power supply system can still operate immediately.
UPS power system on and off
The first boot
(1) Closed in the following order: Energy storage battery switch → Auto bypass switch → Output switch is set to "ON".
(2) press the UPS start panel "open" button, UPS power system will start slowly, "inverter" indicator light, delay 1 minute, "bypass" lights off, UPS to power supply, complete the boot.
After about 10 minutes of no-load operation, the load is started according to the load power from small to large boot sequence.
Daily boot
Just press the UPS panel "ON" button, about 20 minutes later, you can open the computer or other instruments to use. Usually after the start of the UPS to enter a stable work before you can open the load device power switch (Note: manual maintenance switch in the normal operation of the UPS, "OFF" state).
Shut down
First turn off the computer or other equipment, let UPS run for 10 minutes, the heat after discharge, then press the panel "off" button.
Precautions
1) UPS use of the environment should pay attention to good ventilation, conducive to heat, and keep the environment clean.
2) Do not carry inductive load, such as Dianchao Ji, fluorescent, air conditioning, etc., in order to avoid damage to the uninterruptible power supply bad.
3) UPS output load control in about 60% for the best, the highest reliability.
4) UPS with light (such as 1000VA UPS with 100VA load) may cause the battery depth of discharge, will reduce the battery life, should be avoided.
5) the appropriate discharge, contribute to the activation of the battery, such as long-term non-stop electricity, every three months should be cut off the mains with UPS with a load discharge time, this can extend the battery life.
6) for most small UPS, work and then open the UPS, boot to avoid the boot start, get off work should be shut down UPS; UPS for the network room, because most of the network is 24 hours of work, so UPS must also run around the clock.
7) UPS discharge should be promptly charged to avoid the battery due to excessive self-discharge and damage.
