• Single phase 200V to 240V 50/60Hz (up to 2.2kW) for SFEF model
• Single/Three phase 200V to 240V 50/60Hz (up to 2.2kW) for NFU model
• Three phase 200V to 240V 50/60Hz (7.5kW) for LFU model
• Three phase 380V to 480V 50/60Hz (up to 7.5kW) for HFx model
CAUTION: Be sure not to power a three-phase-only inverter with single phase
power. Otherwise, there is the possibility of damage to the inverter and the danger
of fire.
