Caution
！
Connect the unit to batteries with a normal output of 12V DC only. As 6V
batteries voltage is too low, and a 24V battery voltage is too high which will
damage the unit.
Additional Safety Guidelines
！
Do not insert any foreign objects into the unit outlets, vents or fan openings.
Do not expose the unit to rain, water or any other liquid.
Do not connect the unit to any utility power distribution systems or branch
circuits.
Do not use the inverter in temperatures over 104°F(40°C) or under 32°F(0°C).
Failure to follow these safety guidelines will result in personal injury
and/or the damage to the unit. It may also void the warranty.
Certain battery chargers for battery packs used in hand power tools.
These chargers will have a warning label indicating that dangerous
voltages are present at the battery terminals.
Over Input Voltage Shut Off
When the 12 volt DC power supply voltage exceeds 15.5±0.5 volts, the inverter
will automatically shut down, and the digital display showing “OUP”.
Low Input Voltage Shut Off
When the 12 volt DC power supply voltage drops below 10.5±0.3volts, the
inverter will automatically shut down, and the digital display showing “LUP”.
Low Input Voltage Alarm
When the 12 volt DC power supply voltage drops below 11±0.3volts, an audible
alarm will sound, and the digital display showing “LUP”.
Over Heating Shut Off
When the internal temperature exceeds the regulated temperature due to the
