WARNING

Caution

Provide an appropriate stopping device on the machine side to secure safety. (A holding brake is not a stopping device for securing safety.) Not doing so may result in injury.

Provide an external emergency stopping device that allows an instantaneous stop of operation and power interruption. Not doing so may result in injury.

Be sure to install the product in the correct direction and provide specified clearances between the Inverter and control panel or with other devices. Not doing so may result in fire or malfunction.

Caution

Do not allow foreign objects to enter inside the product. Doing so may result in fire or malfunction.

Do not apply any strong impact. Doing so may result in damage to the product or malfunction.

Installation Chapter 2-1

Installation Direction and Dimensions

Install the Inverter under the following conditions.

• Ambient temperature for operation (panel-mounting): -10°C to 50°C

• Humidity: 95% or less (no condensation)

Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally enclosed panel that is completely protected from floating dust.

When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter.

Do not install the Inverter on inflammable material such as wood.

Direction Install the Inverter on a vertical surface so that the characters on the

nameplate are oriented upward.

Dimensions When installing the Inverter, always provide the following clearances to allow

normal heat dissipation from the Inverter.

W = 30 mm min.

Inverter Inverter Inverter

W W W 100 mm min.

Ambient Temperature Control

To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature changes.

If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50°C. The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air temperature as low as possible.

The surface temperature of the Inverter may rise approximately 30°C higher than the ambient temperature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment and wires are easily influenced by heat.

Wiring must be performed by authorized personnel. Not doing so may result in electrical shock or fire.

Be sure to confirm operation only after wiring the emergency stop circuit. Not doing so may result in injury.

Always connect the ground terminals to a ground of 100 Ω or less for the 200V AC class, or 10 Ω or less for the 400V AC class. Not connecting to a proper ground may result in electrical shock.

Install external breakers and take other safety measures against shortcircuiting in external wiring. Not doing so may result in fire.

Confirm that the rated input voltage of the Inverter is the same as the AC power supply voltage. An incorrect power supply may result in fire, injury, or malfunction.

Connect the Braking Resistor and Braking Resistor Unit as specified in the manual. Not doing so may result in fire.

Caution

Be sure to wire correctly and securely. Not doing so may result in injury or damage to the product.

Be sure to firmly tighten the screws on the terminal block. Not doing so may result in fire, injury, or damage to the product.

Do not connect an AC power to the U, V, or W output. Doing so may result in damage to the product or malfunction.
