Wiring - Cautions for Electrical Practices

WARNING: “Suitable for use on a circuit capable of delivering not more
than 100,000 rms symmetrical amperes, 480 V maximum.” For models
with suffix H.

....

HIGH VOLTAGE: Be sure to ground the unit. Otherwise, there is a
danger of electric shock and/or fire.

....

HIGH VOLTAGE: Wiring work shall be carried out only by qualified
personnel. Otherwise, there is a danger of electric shock and/or fire.

....

HIGH VOLTAGE: Implement wiring after checking that the power
supply is OFF. Otherwise, you may incur electric shock and/or fire.

....

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.

....

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

....

CAUTION: If you power a 3-phase-only inverter with single phase
power, you must derate the output current. Be sure to call your Hitachi
distributor for assistence. Otherwise, there is the possibility of damage to
the inverter and the danger of fire.
