Quick Setup Guide
DANGER!
Always disconnect the main power supply before touching any
electrical component associated to the inverter. Several
components can remain charged with high voltages or remain
in movement (fans) even after the AC power is disconnected or
switched off.
Wait at least ten minutes after turning off the input power for the
complete discharge of the power capacitors.
Always connect the grounding point of the inverter to the
protection earth (PE).
