UPS for external batteries
• 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-off UPS. 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
battery pack. Since this UPS implements the "autostart" function, a voltage failure in the
network will lead to an automatic start of the UPS.
"Cold start" function

a
button
.
Note. It is not recommended to use the cold start function if a heavy load is connected.
Sound alarm and protection

short beeps. During battery operation, the UPS emits periodic beeps.
• To turn off this function for a short time, press the button
off the beeps using the button on the back panel
• 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.
• Battery storage conditions must meet the requirements of the battery manufacturer.
