Hitachi L100 Wiring - Cautions for Electrical Practices

L100 Inverter

v

WARNING: “Suitable for use on a circuit capable of delivering not more	.... 2–13
than 5,000 rms symmetrical amperes, 480 V maximum.” For models with
suffix H.
HIGH VOLTAGE: Be sure to ground the unit. Otherwise, there is a	.... 2–13
danger of electric shock and/or fire.
HIGH VOLTAGE: Wiring work shall be carried out only by qualified	.... 2–13
personnel. Otherwise, there is a danger of electric shock and/or fire.
HIGH VOLTAGE: Implement wiring after checking that the power	.... 2–13
supply is OFF. Otherwise, you may incur electric shock and/or fire.
HIGH VOLTAGE: Do not connect wiring to an inverter or operate an	.... 2–13
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	.... 2–19
has been powered, leave it OFF for five minutes before continuing.

Wiring - Cautions for Electrical Practices

CAUTION: Fasten the screws with the specified fastening torque in the	.... 2–15
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-	.... 2–16
tions: • Single/Three phase 200 to 240 V 50/60 Hz (up to 2.2kW) • Three
phase 200 to 230V 50/60Hz (above 2.2kW) • Three phase 380 to 460 V
50/60Hz
CAUTION: Be sure not to power a three-phase-only inverter with single	.... 2–16
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	.... 2–17
terminals. Otherwise, there is the possibility of damage to the inverter
and the danger of injury and/or fire.
