SAFETY INSTRUCTIONS
• KEMOT PROsinus emergency power supply is designed for household and o󰀩ce
use. Do not use this device with specialized equipment or apparatuses (e.g.
industrial, medial equipment).
• Do not overload device. Operating this device with load higher than nominal may
lead to damaging this device.
• Note: Device may work on overload for a short period of time.
• Do not disassemble this device nor open the housing. High voltage might be still
present on the inside elements of the device, even after it has been switched o󰀨.
• Do not use this device if it is not working properly. In such case, turn the device o󰀨
immediately, disconnect it from power supply mains and switch the Battery switch
to OFF.
• Any repair can be carried out in an authorized service point exclusively.
• In case of re, use only dry powder extinguisher. Using water or other types of re
extinguishers can lead to electrocution.
• Position the device vertically, in a properly ventilated place with suitable temperature.
Warning: do NOT cover cooling fan of the device; it may lead to overheat.
• Protect this device from water, humidity as well as sources of heat and direct sunlight.
• Before use, make sure the device is properly grounded.
• Power supply socket should be easily accessible and located near the appliance.
• Warning: Inappropriate use of the device may lead to re or electrocution.
To estimate operation time in case of power-cut, when the external device is supplied
with built-in battery of this emergency power supply device, refer to formula below:
100 W of load = → 10 A current consumption from the battery
Example: having in mind that built-in battery capacity of the URZ3424 is 55 Ah, then with
100 W load estimated operation time is around 55 Ah/10 A≈ (around) 5,5 h.
FEATURES
• KEMOT inverter with pure sine wave serves as an emergency power supply device
for equipments such as: central heating furnace, TV, refrigerator, induction stove,
electric fans, etc.
• Wide range of input voltage, high degree of output voltage accuracy, automatic
voltage regulation.
• Build in protection from overload, short circuit, overvoltage, undervoltage, overheat.
• LED display with current state indicators.

OPERATION
Before plugging this device to power supply mains, make sure that:
• this device is placed in a well ventilated location,
• it is properly grounded,
Note:
• after plugging the device to power supply, output sockets will be under electricity
immediately, even when the equipment is powered o󰀨.
• do not connect this device to overloading equipment (e.g. hair dryer, vacuum
cleaner, etc).
Important!
Device overload will be signalized with sound signal. Please reduce device load and
restart the inverter.
Sound signaling
• Four sound signals: power cut; automatic switch to emergency power supply;
• Sound signal every 1 second: low battery level or overload;
• Rapid sound signals: improper operation, failure.
Switching o󰀨
• Disconnect the external device,
• Use the inverter power switch to turn it o󰀨,
• Move the battery switch to OFF.
STORAGE
• If the device is not going to be used for a longer period of time, power it on and use
it with connected load regularly. Remember that battery switch needs to be in ON
position.
• at least once in 4 months for 12 hours - if the storage temperature is lower than
25°C.
• at least once every 2 months for 12 hours - if the storage temperature is higher
than 25°C.
• IMPORTANT: do not store the device with completely discharged battery. If the
device is not going to be used for a longer period of time, connect the device to
power supply mains until the built-in battery is fully charged. Before storing, make
sure the device has cooled down before storing.
CLEANING
Clean this device with soft, dry cloth. Do not use any chemical agents to clean this
product. Before cleaning, make sure the device is switched o󰀨 and disconnected from
the power supply.
