Toshiba TOSVERT VF-AS3 Schnellstartanleitung Seite 5

• Carry the inverter by two people or more when the inverter is the model mass 20kg or more (VFAS3-
2110P - 2370P, VFAS3-4220PC - 4750PC, VFAS3-4110PCE - 4370PCE). If you carry the inverter
alone, this will result in injury.
• Transport a large-capacity inverter (VFAS3-2450P, 2550P, VFAS3-4900PC - 4280KPC, VFAS3-
4450PCE - 4750PCE) by a crane. If you transport a heavy load by hand, this will result in injury. Please
take the utmost care for the operator's safety, and please handle the inverter carefully in order not to
damage the product.
For lifting the inverter, hang the inverter with wire ropes via hanging bolts
(hanging holes) provided at upper part or lower part of the inverter as shown
below.
• Please make sure that the inverter is hanged by two wire ropes in a balanced
manner, and please be careful that the inverter does not receive excessive force
Mandatory during the hanging operation.
action • Carry the inverter with the cover attached, and avoid holding or putting your
hands in the wiring holes during the transportation. Otherwise, you can have
your hands pinched and injured.
• Transport the operation panel in accordance with law. Please transport the
operation panel by airplane or ship in accordance with law as a lithium battery is
used in the operation panel.
• Install the inverter at a place which can support the unit's mass. If you install the
inverter at a place which does not support the unit's mass, the unit will fall,
resulting in injury.
• Install the mechanical brake when it is necessary to hold a motor shaft. A brake
function of the inverter cannot perform mechanical hold, and it results in injury.
■ Wiring
• Do not connect power supply to the output (motor side) terminals [U/T1], [V/T2] and [W/T3]. Connecting
power supply to the output will damage the inverter and result in fire.
• Do not insert a braking resistor between DC terminals [PA/+] and [PC/-] or [PO] and [PC/-]. This will
result in fire. Please connect the braking resistor in accordance with the instruction manual.
• Do not touch wires of equipment (e.g. ELCB) that is connected to the inverter power side at least 15
minutes after turning off the power. If an electric charge remains in a capacitor in the inverter, touching
the wires before the indicated time will result in electric shock.
• Do not touch output terminals [U/T1], [V/T2] and [W/T3] on the PM motor side while the PM motor is
Prohibited
rotating even after turning off the power. While the PM motor is rotating even after the power is turned
off, as a high voltage is generated in the output terminals [U/T1], [V/T2] and [W/T3] on the PM motor
side, touching the output terminals will result in electric shock.
• When using this 480V class inverter with a power supply system that is grounded in other than the
neutral point, the grounding capacitor should not be grounded (or the capacity of the grounding
capacitor should not be increased). Otherwise, it will result in failure or fire.
• Electrical construction work must be done by a qualified expert. Erroneous connection of power supply
by someone who does not have that expert knowledge will result in fire or electric shock.
• Install a protective device against earth leakage such as an earth leakage circuit breaker (ELCB)
between the power supply and the inverter (primary side) into your system. If proper protection device
against earth leakage is not installed, it can result in fire.
• Connect output terminals (motor side) correctly. If the phase sequence is incorrect, the motor will
operate in reverse and that can result in injury.
• Wiring must be done after installation. If you perform wiring prior to installation, this will result in electric
Mandatory
shock or other injury. Verify that the power is turned off and the charge lamp is off before starting wiring.
action
If you perform wiring without verification, this will result in electric shock.
• Tighten the screws on the terminal block to specified torque. If the screws are not tightened sufficiently
to the specified torque, this will result in fire.
• Verify that the power supply voltage is within +10% and -15% (±10% when the load is 100% in
continuous operation) of the applied power supply voltage written on the name plate. If you do not use
the appropriate power supply voltage, this will result in failure or fire.
• The grounding wire must be connected securely. If the grounding wire is not securely connected, when
the inverter has failure or earth leakage, this will result in electric shock or fire.
