HIGH VOLTAGE: Be sure to ground the unit. Otherwise, there is a
danger of electric shock and/or fire.
.... 2–17
HIGH VOLTAGE: Wiring work shall be carried out only by qualified
personnel. Otherwise, there is a danger of electric shock and/or fire.
.... 2–17
HIGH VOLTAGE: Implement wiring after checking that the power
supply is OFF. Otherwise, you may incur electric shock and/or fire.
.... 2–17
HIGH VOLTAGE: Do not connect wiring to an inverter or operate an
inverter that is not mounted according the instructions given in this
manual. Otherwise, there is a danger of electric shock and/or injury to
personnel.
.... 2–17
WARNING: Make sure the input power to the inverter is OFF. If the drive
has been powered, leave it OFF for five minutes before continuing.

CAUTION: Fasten the screws with the specified fastening torque in the
table below. Check for any loosening of screws. Otherwise, there is the
danger of fire.

CAUTION: Be sure that the input voltage matches the inverter specifica-
tions: • 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
.... 2–20
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.
.... 2–20
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.
