Never disassemble, modify or repair the unit, keep the front cover attached when power is on, and avoid touching terminals while the inverter is energized.
Large capacity models should be lifted with a crane, using balanced sling ropes, and the unit must be placed on a non‑flammable base that can support its weight.
Turn off all input power, wait at least 15 minutes until the charge lamp is off, and verify the DC voltage with a tester capable of measuring 800 VDC or more.
