is likely to result in serious injury or may result in death. Additionally there may be severe property damage.

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

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.

Do not put on or take off the Digital Operator•control circuit terminal block•terminal block cover 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 remove the terminal block cover during the power supply and 5 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.

Do not change wiring, mode change switches, optional devices or replace cooling fans while power is being supplied. Doing so may result in a serious injury due to an electric shock.

Page 8

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 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.

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.

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.

•Do not connect the power supply other than to R/L1, S/L2, or T/L3.

•Do not remove the short-circuit bar between P/+2 and +1, except when a DC reactor is connected.

Note 1: Install an earth leakage breaker on the power supply input side.

(Select an earth leakage breaker having a larger high-frequency sensed current and avoid unnecessary operations.) If the wiring between the Inverter and the motor is too long (longer than 10 m), the thermal relay may malfunction due to harmonics. Install an AC reactor on the Inverter output side, or use a current sensor instead of the thermal relay.

Note 2: Connect securely to the ground as specified (type-D grounding for 200-V class, and type-C

• For the main circuit terminals, always use insulated electrical wires with a rated voltage of 600 V and a rated temperature of 80°C or higher.

• Use the crimp-type terminal with an insulating sleeve to connect to the terminals.

• Up to two wires can be connected to one terminal.

• To prevent possible voltage drops, increase the wire size in accordance with the cable length.

• To connect the 100-V or 200-V model to the relay output terminal, use a wire of 0.75 mm

• To connect seven wires or more to the control circuit terminal block, use a shield wire of 0.5 mm

or less.

• Strip the signal line by 5 to 6 mm, and connect the exposed wire. (In the case of stra nded wires, make sure that the wires are not unraveled.)

• Make sure that the maximum outside coating diameter of the signal line is 2.0 mm or less (except for the alarm signal line). (For the mark tube mounted cable and multi-core cable, keep both the mark tube and the sheathstripped length 40 mm or more from the connecting end. A thick line may prevent proper closing of the cover of the terminal block.)

• To meet the UL standards, always insert a UL-standard fuse (J type) on the power supply side.

• Use a ground wire with a larger diameter than that of the power cable shown above.

Wiring the Main Circuit Terminals (Input Side)

Installing a Molded-case Circuit Breaker (MCCB)

•Always connect the Inverter and power supply via a molded-case circuit breaker (MCCB) to protect the Inverter from damage that may result from short-circuiting.

•Always connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an MCCB, according to the Inverter capacity.

•Install one MCCB per Inverter.

•Choose an appropriate MCCB capacity according to the fuse size on page 2-15.

•When choosing an MCCB's time characteristics, be sure to consider the Inverter's overload protection (1 minute at 150% of the rated output current).

•By programming the sequence as illustrated below, you can turn off the power via the relay outputs (MA, MB, and MC) for the 3G3MX Series.

2-3 Wiring

Design

* Terminal symbols for 3G3MX-AE are indicated in parentheses ( ).

Installing a Ground Fault Interrupter

•The Inverter's output uses high-speed switching, and so generates high-frequency current leakage. (Generally, if the power cable is 1 m, the leakage current is approx. 100 mA per Inverter, and approx. 5 mA is added per additional meter.)

•At the power supply input part, install a special-purpose ground fault interrupter for Inverters that exclude high-frequency leakage current and detect only the leakage current within a frequency range that is hazardous to humans. (Choose a ground fault interrupter with a sensitivity current of at least 10 mA per Inverter.)

•Alternatively, use a general ground fault interrupter with a sensitivity current of 200 mA or more per Inverter, and with an operating time of 0.1 s or more.

Installing a Magnetic Contactor (MC)

•If the power supply of the main circuit is shut off due to sequencing, a magnetic contactor (MC) can be used. (When forcibly stopping the load with an MC on the primary side of the main circuit, however, the regenerative braking does not work and the load coasts to a stop (free run).)

•Frequently opening and closing the magnetic contactor (MC) to start and stop a load may cause the Inverter to break down. To extend the life of the Inverter's internal electrolytic capacitor, limit the frequency to no more than once every 30 minutes.

Connection Sequence to the Terminal Block

•Input power supply can be connected to any terminal because the phase sequence of the input power supply is irrelevant to that of the terminal block (R/L1, S/L2, and T/L3).

2-18

Page 44

Design

2-3 Wiring

Installing an AC Reactor

•If the Inverter is connected to a large-capacity power transformer (660 kVA or more) or the phase advance capacitor is in use, a large peak current may flow through the input power circuit, causing the converter unit to break down.

•Install an optional AC reactor on the input side of the Inverter. An AC reactor will also improve the power factor of the power input side.

Installing a Surge Absorber

•Always use a surge absorber or diode when magnetic contactors (MC), electromagnetic relays, solenoid valves, solenoid, and magnetic brakes are used.

Connecting a Regenerative Braking Unit

When running a load with a large inertia or a vertical axis, regenerative energy will return to the Inverter. If overvoltage in the main circuit is generated during deceleration, this indicates that the regenerative energy exceeds the capacity of the Inverter. In this case, use a regenerative braking unit.

•When using a regenerative braking unit, be sure to include a sequence whereby the power supply for the Inverter will be turned off in the event of abnormal overheating. Not doing so may result in fire.

For a regenerative braking unit: Use the error contact output (MA, MB).

Installing a Noise Filter on the Input Side

•The Inverter's output uses high-speed switching, so noise may be transmitted from the Inverter to the power line, affecting peripheral devices.

•It is recommended that a noise filter be installed on the input side to minimize noise transmission. (Installing a noise filter on the input side can also reduce the noise from the power line to the Inverter.)

Wiring the Main Circuit Terminals (Output Side)

Connect the Terminal Block to the Load

•Connect motor output terminals U/T1, V/T2, and W/T3 to motor lead wires U, V, and W.

•Check that the motor rotates forward with the forward command. Switch over any two of the output

Never Connect a Power Supply to the Output Terminals

terminals (U/T1, V/T2, W/T3) and reconnect if the motor rotates in reverse to the forward command.

•If voltage is applied to the output terminals, the internal circuit of the Inverter will be damaged. Never connect a power supply to output terminals U/T1, V/T2, or W/T3.

Design

Never Short-circuit or Ground the Output Terminals

•Never touch the output terminals by hand.

•If the output wires come into contact with metal materials, an electric shock or ground fault will occur. This is extremely hazardous. Be careful not to short-circuit the output wires.

Do Not Use a Phase Advance Capacitor or Noise Filter

•Doing so may result in damage to the Inverter or cause the parts to burn. Never connect a phase advance capacitor or LC/RC noise filter to the output circuit.

Do Not Use an Electromagnetic Switch

•If a load is connected to the Inverter during running, an inrush current will actuate the overcurrent protective circuit in the Inverter. Do not connect an electromagnetic switch or magnetic contactor (MC) to the output circuit.

Install a Noise Filter on the Output Side

Connect a noise filter to the output side of the Inverter to reduce induction and radio noise.

Cable Length Between Inverter and Motor

Use a cable of 50 m or less between the Inverter and the motor. If the cable length is increased, the stray capacitance between the Inverter outputs and the ground is increased proportionally. An increase in stray capacitance causes high-frequency leakage current to increase, affecting the current detector in the Inverter's output unit and peripheral devices. If your system configuration requires a cable length of 50 m or more, perform the following:

•Wire in metallic ducts.

•Use separate cables for each phase.

•Set the Inverter to a lower carrier frequency (b083).

Do Not Use Single-phase Motors

•A single-phase motor uses the capacitor start method or split-phase start method to determine its rotation direction at startup, and thus is not suitable for the variable speed control via the Inverter. Do not use single-phase motors.

*If a capacitor start motor is used, the capacitor may be damaged by a sudden electric charge and

discharge caused by Inverter output. If a split-phase start motor is used, the startup coil may burn because the centrifugal switch does not operate.

*1. By factory default, multi-function output terminals, [P1] and [P2] are set to NO contact. To switch to NC contact,

change the C031 and C032 settings. In addition, these terminals are reset to NO contact when initialized.

*2.The factory default setting (C036) of the relay output terminals (MA, MB-MC) is set to NC contact.

In addition, these terminals are reset to NC contact when initialized. To use the Inverter as an alternative to a conventional model or for built-in use with a system, check the

contact logic of the relay output terminal setting (C036), and match the logic with that of the peripheral circuit before use. If these contact logics conflict with each other, a system breakdown may occur.

Conforming to EC Directives

Conforming Standards

•EMC directive EN 61800-3

•Low-voltage directive EN 61800-5-1

Concept of Conformity

EMC Directive

OMRON products are the electrical devices incorporated and used in various machines or manufacturing equipment. For this reason, we make efforts to conform our products to their related EMC standards so that the machines or equipment which have incorporated our products should easily conform to the EMC standards. The 3G3MX models have conformed to the EMC directive EN 61800-3 by following the installation and wiring method as shown below. Your machines or equipment, however, vary in type, and in addition, EMC performance depends on the configuration, wiring, or location of the devices or control panels which incorporate the EC directive conforming products. This in turn does not allow us to confirm the condition and the conformity in which our products are used. Therefore, we appreciate confirmation of the final EMC conformity for the whole machine or equipment on your own.

Wiring the Power Supply

•Be sure to connect the power input terminals (R/L1, S/L2, and T/L3) and power supply via an EMC conforming dedicated noise filter 3G3AX-EFI .

•Keep the ground cable as short as possible.

•Keep the cable between the Inverter and the noise filter as short as possible.

Connecting a Motor to the Inverter

•When connecting a motor to the Inverter, be sure to use shield braided cables.

•Keep the cables as short as possible.

Low-voltage Directive

The 3G3MX models have conformed to the EMC directive EN61800-5-1 by performing the machine installation and wiring as shown below.

•The 3G3MX models are an open type device. Be sure to install it inside the control panel.

•The power supply and voltage (SELV) with reinforced or double insulation should be used for wiring to the control circuit terminals.

•To satisfy requirements of the LVD (low-voltage) directive, the Inverter must be protected with a molded case circuit breaker (MCCB) in case a short-circuiting accident occurs. Be sure to install a molded case circuit breaker (MCCB) on the power supply side of the Inverter.

•Use one molded case circuit breaker (MCCB) per Inverter.

•Use the crimp-type terminal with an insulation sleeve to connect to the main circuit terminals.

•When not using the braking resistor or braking resistor unit, connect the crimp-type terminal with an insulation sleeve to the braking resistor connection terminals (P/+2, N/-).

WARNING

Operation

Do not remove the terminal block cover during the power supply and 5 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.

Do not change wiring, mode change switches, optional devices or replace cooling fans while power is being supplied. Doing so may result in a serious injury due to an electric shock.

CAUTION

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.

Safety Information

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.

Precautions for Use

Error Retry Function

•Do not come close to the machine when using the error retry 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.
