This inverter produces 230 V AC; improper use can cause electric shock, fire, or serious injury. Read the supplied operating manual completely before installation and first use, and keep it for later reference. Use the product only for its intended purpose; never operate it in damp, wet, or salty environments, near flammable materials or aggressive vapors, or in areas with an explosion hazard. Do not operate the device if it or its connection cables show visible damage; a damaged cable must be replaced by the manufacturer, its service department, or a similarly qualified person, and repairs may only be carried out by qualified specialists. Observe correct battery polarity and never allow the red and black terminals to touch; reverse polarity damages the unit. Use battery cables with adequate cross-section, route them so they cannot be pinched or damaged, and never touch bare wires. Disconnect the device from the power supply before any cleaning, fuse replacement, or other work on the unit; note that parts of the device can remain live even after the fuse has tripped. Mount the inverter on a stable surface so it cannot tip or fall, keep at least 10 cm clearance on all sides for ventilation, and never cover the air inlets and outlets. Keep away from heat sources and out of the reach of children; this device is not a toy. Do not exceed the rated continuous power and account for start-up peaks of connected devices (see technical specifications and manual). For installation in vehicles or mobile units, observe the grounding and isolation-monitoring requirements described in the operating manual.
