Insert the three hole plug on the body of the UPS power supply into the socket of the mains power supply, turn on the UPS power switch, and let the UPS power supply work normally. Then plug the power cord plugs of the computer host and monitor into the sockets behind the UPS power supply body, and turn it on one by one.

Uninterruptible power supply is a system equipment that connects a battery (mostly lead-acid maintenance free battery) to a host and converts DC power into mains power through module circuits such as host inverters. Mainly used to provide stable and uninterrupted power supply to single computers, computer network systems, or other power electronic devices such as solenoid valves, pressure transmitters, etc. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load for use. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the internal battery; When the mains power is interrupted (accident power outage), UPS immediately supplies 220V AC power from the battery to the load through the method of inverter zero switching conversion, so as to maintain normal operation of the load and protect the software and hardware of the load from damage. UPS equipment usually provides protection against high or low voltage.

UPS battery wiring: The red pole of the battery is the positive pole, and the black pole is the negative pole. The batteries are connected in series in the battery box, which means that the positive pole of one battery is connected to the negative pole of another battery. According to this connection method, there will be one positive and one negative lead wire left, which will be connected to the battery discharge port. Pay attention to matching them one by one, generally left positive and right negative. When connecting, pay attention to battery short circuit. Water ingress into the battery in a short time will not affect battery performance. Water is a weak electrolyte with weak conductivity, but it must be dried immediately, otherwise it will oxidize the pole and cause the pole to fall off, resulting in battery damage.
