1. Product introduction
UPS power supplies in this series provide comprehensive protection against overvoltage and voltage spikes as
well as against high power density. Thanks to the built-in voltage stabilizer, the UPS can continue to work online
and provide stable power when voltage fluctuations. The built-in microprocessor driver ensures high reliability.

liquid-containing vessels on or near the UPS.
Caution! In the event of any emergency, press the off button and disconnect the power cord from the AC
power supply to properly disable UPS.
Caution! Do not attach a power strip or surge suppressor to the UPS.
Caution! If the UPS is equipped with a metal housing, it is necessary to reduce the leakage current below
3.5mA for safety reasons during installation of the UPS.
Pay attention to the risk of electric shock. Disconnecting the device from the network can be just as dangerous
as there may still be voltage available through battery power. The battery supply should be disconnected and
isolated before maintenance or service work are made inside the UPS.
Caution! Servicing of batteries should be performed or supervised by personnel who have knowledge about
batteries and required precautions.
Caution! When replacing the batteries, use the same number and same type of batteries,
Caution! Internal battery voltage is 12V DC. Sealed, lead-acid, 6-cell battery.
Caution! Do not dispose batteries in fire. The battery may explode. Do not open or mutilate the battery.
Released electrolyte is harmful to the skin and eyes.
Caution! Do not use liquid or spray detergent to clean the UPS. Unplug the UPS before cleaning.
Caution! The battery may cause an electric shock and short circuit. Before replacing it, the following
