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 the slide switch (SW1), install/remove the Digital Operator and optional
devices, or replace the cooling fan 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 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 and 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 overheating is
detected in the braking resistor and 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.
