Please use the terminal arrangement below corresponding to your inverter model.
NOTE: An inverter powered by a portable power generator may receive a distorted
power waveform, overheating the generator. In general, the generator capacity should be
five times that of the inverter (kVA).
CAUTION: Be sure that the input voltage matches the inverter specifications:
• Single/Three phase 200 to 240 V 50/60 Hz (up to 2.2kW) for NFEF/NFU models
• Three phase 200 to 240V 50/60Hz (above 2.2kW) for LFU models
• Three phase 380 to 480 V 50/60Hz for HFEF models
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.
