Safety Precautions
Alert Symbols in this Document
WARNING
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.
SYSDRIVE MX2 Series USER'S MANUAL (3G3MX2-Axxxx)
5
Safety Precautions
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 p ower 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.
CAUTION
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.

Precautions for Safe Use
Main Circuit Power Supply
Confirm that the rated input voltage of the Inverter is the same as AC power supply voltage.
Operation and Adjustment
Be sure to confirm the permissible range of motors and machines before operation because the
Inverter speed can be changed easily from low to high.
Provide a separate holding brake if necessary.
Maintenance and Inspection
Be sure to confirm safety before conducting maintenance, inspection or parts replacement.
The life of the capacitor depends on ambient temperatures. Refer to the diagram of product life
specified in the manual. When the capacitor stops operating at the end of the product's life, the

Precautions for Correct Use
Precautions for Correct Use
Installation
Mount the product vertically on a wall with the product's longer sides upright.
The material of the wall has to be nonflammable such as a metal plate.
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
replace parts according to their service life.

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
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 Inver ter 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.

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.
