4. TECHNICAL DESCRIPTION
Operating principle
•This device is designed to operate with lead-acid maintenance-free 12 V AGM type batteries and
belong to line-interactive uninterrupted power supply of continuous action with a long backup time.
The principle of operation is based on the conversion of DC current from external batteries into pure
sinewave AC current. The main purpose is to power household and industrial equipment critical to
the form of the input current (boiler equipment, automation systems, etc.).
•The device is equipped with an automatic voltage regulator (AVR), which allows you to ensure the
correct power supply of the load when the mains voltage increases/decreases without switching to
battery operation mode.
•The "autostart" function ensures automatic switching on after power supply. If the input voltage
after the power supply exceeds the limits of 160 V - 265 V, "autostart" is not activated, protection
against low or high voltage is activated.
Recommendations for choosing batteries
•Select the capacity of the battery depending on the power of the connected load and for the
required power reserve time, see tables 1 and 2 below. Based on the selected capacity, select the
specific battery.
•The minimum recommended battery capacity is 50Ah for the 500VA model and 100Ah for the
1000VA model.
•Battery storage conditions must meet the requirements of the battery manufacturer.
Notes:
•When using a battery of two or more units, they must be of the same type and capacity (if the
batteries have different capacities, they will have different internal resistance, as a result of which
the charge level will be different).

•Connect the UPS to a single-phase mains using the power cord. It is not necessary to turn on the
UPS by button, after connecting to the mains - "autostart" function will start it automatically.
•Batteries need to be charged.
•To do this, leave the UPS on until the battery is fully charged.
•After charging the battery, press and hold the button until the device turns OFF.
•Disconnect the UPS from the network by removing the plug of the power cord from the outlet.
•Connect consumer devices to the switched-offUPS. Insert the mains plugs of the consumer
devices into the UPS sockets.
•Reconnect the UPS plug to the mains, the "autostart" function will start it automatically.
•Then turn on the connected devices (the most powerful device first and the least powerful device
last) using their switches.
Notes:
•If you need to forcibly shut down the UPS, first turn off the mains circuit breakers of the
consumers, and then turn off the UPS in the order described above. To turn on the UPS again,
press and hold the button.
•If the UPS is not used for a long time, the battery should be charged every three months.
Check the battery manufacturer's care instructions.
•If the UPS is not used for a long time, disconnect it from the mains and disconnect the

short beeps. During battery operation, the UPS emits periodic beeps.
•To turn offthis function for a short time, press the button bon the front control panels, or turn
offthe beeps using the button on the back panel kto permanently disable beeps.
•In the case of a low battery charge (in battery operation mode), the UPS emits sound signals.
•If a connected load is higher than the rated load, the UPS will beep and then automatically shut
down.
•In the case of an emergency situation (short circuit in the connected device or connection of the
device with a load higher than the nominal one), fuse may fail.
Storage conditions
•The temperature and humidity of the room where you intend to install the device must meet the
standards specified in the "Technical characteristics" table.
•The UPS should be stored with fully charged batteries.
