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.
Doing so may result in a serious injury due to an electric shock.

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-Axxxx)

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.

Restart after Trip

 Do not come close to the machine when using the Restart During Momentary Power Interruption

function because the machine may abruptly start when stopped by an alarm.

 Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine

may abruptly start.

Operation Stop Command

 Provide a separate emergency stop switch because the STOP key on the Digital Operator is valid

only when function settings are performed.

 When checking a signal during the power supply and the voltage is erroneously applied to the

control input terminals, the motor may start abruptly. Be sure to confirm safety before checking a
signal.

Maintenance and Parts Replacement

 The Inverter consists of many parts, and these parts must operate properly in order to make full

use of the designed functions of the Inverter. Among the electronic components, there are some
that require maintenance depending on their usage conditions. In order to keep the Inverter
operating normally over a long period of time, it is necessary to perform periodic inspections and

 When transporting the Inverter, hold the fin, not the fro nt cover or terminal block cover.
 Do not connect an AC power supply to the control I/O te rminals. Doing so may cause damage

to the Inverter.

 Be sure to tighten the screws on the terminal block securely.Perform the wiring after installing

the Inverter.

 Do not connect any load other than the 3-phase induction motor to the output terminals (U/

T1, V/T2, W/T3) of the Inverter.

 Take appropriate and sufficient countermeasures when using the Inverter in the following

locations.Not doing so may result in damage to the Inverter.

 Locations subject to static electricity or other forms of noise.
 Locations subject to strong electromagnetic fields.
 Locations close to power supplies.

Main Circuit Power Supply

 Confirm that the rated input voltage of the Inverter matches the AC power supply voltage.

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 b ody.

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 mis t, o r s alt. 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.
