Safety Precautions

Indications and Meanings of Safety Information

In this user's manual, the following precautions and signal words are used to provide information to ensure the safe use of the 3G3MX2 Inverter. The information provided here is vital to safety. Strictly observe the precautions provided.

Meanings of Signal Words

Alert Symbols in this Document

Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury, or may result in serious injury or death. Additionally there may be significant property damage.

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage.

WARNING

CAUTION

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.

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 block cover during the power supply and 10 minutes after the power shutoff. Doing so may result in a serious injury due to an electric shock.

Do not operate the Digital 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 has been 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 shutoff function is activated.

Do not change wiring, slide switches, or optional devices while power is being supplied. Always turn off the power supply to the Inverter before changing wiring, changing the slide switches, or attaching/removing options.

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 shutoff. Doing so may result in a burn.

WARNING

Safety Precautions

SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-A@@@@)

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 overheating 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 this product. Doing so may result in an injury.

SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-A@@@@)

Design

Precautions for Correct Use

Installation

 Install the Inverter vertically on a wall.

Install the Inverter on a nonflammable wall surface material, like metal.

Installation Environment

Make sure the ambient temperature remains within the rated range (−10 to 50°C). Take note that if the ambient temperature reaches or exceeds 40

C, the carrier frequency and output current must be derated. If the Inverter is used in an environment exceeding the allowable operating temperature range, the product life of the Inverter (specifically, the capacitor) will be shortened. Measure and check the temperature approx. 5 cm from the bottom center of the Inverter body.

Provide sufficient space around the Inverter because it can become very hot (up to 150°C or so). Keep the Inverter away from heating elements (such as a Braking Resistor, reactor, etc.). Although side-by-side installation is possible. The ambient temperature of the installation site must not exceed 40°C and the carrier frequency and output current must be derated if side-byside installation is used.

Do not install the Inverter in hot, humid sites or other sites subject to frequent bedewing. Make sure that the humidity in the installation site is within the allowable operating range (20% to 90% RH), as defined in the standard specifications.

Design

In particular, make sure that the installation site is free from condensation. If condensed water adheres to the Inverter's internal parts, the electronic components may short-circuit, causing failure of the Inverter. In addition to avoiding condensation, avoid installing the Inverter under direct sunlight. Avoid an environment where the Inverter may be exposed to dust, gases (corrosive, explosive, and/or flammable), grinding fluid mist, or salt. If a foreign object (e.g. dust) enters the Inverter, it could result in failure of the Inverter. If using the Inverter in a dusty place, take appropriate measures. (For example, place the Inverter in a closed panel.)

When several Inverters are installed in a panel and a ventilation fan is mounted in the panel, be careful about the layout of the Inverters and the air intake apertures. Depending on the layout, the Inverter's cooling effect may deteriorate, resulting in an increase in the ambient temperature.
