Turn off the power supply and implement wiring correctly.
Not doing so may result in a serious injury due to an electric shock.
Wiring work must be carried out only by qualified personnel.
Not doing so may result in a serious injury due to an electric shock.
Do not change wiring and slide switches (SW1), put on or take off Operator and optional devices,
replace cooling fans while the input power is being supplied. Doing so may result in a serious injury
due to an electric shock.
Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or
fire.
(200-V class: type-D grounding, 400-V class: type-C grounding)
Do not remove the terminal cover during the power supply and 10 minutes after the power shut off.
Doing so may result in a serious injury due to an electric shock.
Do not operate the Operator or switches with wet hands.
Doing so may result in a serious injury due to an electric shock.
Inspection of the inverter must be conducted after the power supply was turned off. Not doing so
may result in a serious injury due to an electric shock.
The main power supply is not necessarily shut off even if the emergency shut off function is activated.
Do not touch the inverter fins, braking resistors and the motor, which become too hot during the
power supply and for some time after the power shut off. Doing so may result in a burn.
Do not connect resistors to the terminals (+1, P/+2, N/–) directly. Doing so might result in a
small-scale fire, heat generation, or damage to the unit.
Install a stop motion device to ensure safety. Not doing so might result in a minor injury.
(A holding brake is not a stop motion device designed to ensure safety.)
Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking
resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might
result in a moderate burn due to the heat generated in the braking resistor/regenerative braking
unit. Configure a sequence that enables the inverter power to turn off when unusual over eating is
detected in the braking resistor/regenerative braking unit.
The inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or
other property. Place covers on the openings or take other precautions to make sure that no metal
objects such as cutting bits or lead wire scraps go inside when installing and wiring.
Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the
inverter capacity on the power supply side.
Not doing so might result in damage to property due to the short circuit of the load.
Do not dismantle, repair or modify the product.
Doing so may result in an injury.
