CAUTION: Be sure that the input voltage matches the inverter specifications:
 Single-phase 200 to 240 V 50/60 Hz (0.1kW~2.2kW) for SF models

Three-phase 200 to 240 V 50/60 Hz (0.1kW~15kW) for LF models
 Three-phase 380 to 480 V 50/60Hz (0.4kW~15kW) for HF 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.
CAUTION: Be sure not to connect an AC power supply to the output terminals.
Otherwise, there is the possibility of damage to the inverter and the danger of injury
and/or fire.
CAUTION: Remarks for using ground fault interrupter breakers in the main power
supply: Adjustable frequency inverter with integrated CE-filters and shielded
(screened) motor cables have a higher leakage current toward earth GND. Especially
at the moment of switching ON this can cause an inadvertent trip of ground fault
interrupters. Because of the rectifier on the input side of the inverter there is the
possibility to stall the switch-off function through small amounts of DC current.
Please observe the following:
 Use only short time-invariant and pulse current-sensitive ground fault interrupters
with higher trigger current.
 Other components should be secured with separate ground fault interrupters.
 Ground fault interrupters in the power input wiring of an inverter are not an
absolute protection against electric shock.
CAUTION: Be sure to install a fuse in each phase of the main power supply to the
inverter. Otherwise, there is the danger of fire.
CAUTION: For motor leads, ground fault interrupter breakers and electromagnetic
contactors, be sure to size these components properly (each must have the capacity for
rated current and voltage). Otherwise, there is the danger of fire.
