3. INSTALLATION

CAUTION INSTALLATION PRECAUTIONS

• Use the product within the generic environment specifications described in this manual. Never use the product in areas with excessive dust, oily smoke, conductive dusts, corrosive gas (salt air, Cl2, H2S, SO2 or NO2), flammable gas, vibration or impacts, or exposed to high temperature, condensation, or rain and wind. If the product is used in such conditions, electric shock, fire, malfunctions, deterioration or damage may occur.

• Do not touch the conductive parts of the product directly to avoid failure or malfunctions.

• Install the product securely using a DIN rail or mounting screws.

• Install the product on a flat surface. If the mounting surface is rough, undue force will be applied to the PC board, thereby causing nonconformities.

• When drilling screw holes or wiring, make sure cutting or wire debris does not enter the ventilation slits. Failure to do so may cause fire, equipment failures or malfunctions.

• Be sure to remove the dust proof sheet from the PLC’s ventilation port when installation work is completed. Failure to do so may cause fire, equipment failures or malfunctions.

FX3GE QUICK START MANUAL

Mitsubishi Electric Automation, Inc.

• Connect the extension cables, peripheral device cables, input/output cables and battery connecting cable securely to their designated connectors. Unsecured connection may cause malfunctions.

• Turn off the power before attaching or detaching the following devices. Failure to do so may cause device failures or malfunctions.

 Peripheral devices, display modules and battery.

• When a dust proof sheet is supplied with units, keep the sheet applied to the ventilation slits during installation and wiring work.

• To prevent temperature rise, do not install the PLC on a floor, a ceiling or a vertical surface. Install it horizontally on a wall.

• Keep a space of 50mm (1.97") or more between the unit main body and another device or structure (part A). Install the unit as far away as possible from highvoltage lines, high-voltage devices and power equipment.

DANGER WIRING PRECAUTIONS

• Make sure to cut off all phases of the power supply externally before attempting installation or wiring work. Failure to do so may cause electric shock or damage to the product.

n CAUTION FOR COMPLIANCE WITH EC DIRECTIVE

Installation in Enclosure

Programmable logic controllers are open-type devices that must be installed and used within conductive control boxes. Please use the FX3GE Series programmable logic controllers while installed in conductive shielded control boxes. Please secure the control box lid to the control box (for conduction). Installation within a control box greatly affects the safety of the system and aids in shielding noise from the programmable logic controller.

Analog input/output

The analog input/output have been found to be compliant to the European standards in the aforesaid manual and directive. However, for the very best performance from what are in fact delicate measuring and controlled output devices, Mitsubishi Electric would like to make the following points.

As analog devices are sensitive by nature, their use should be considered carefully. For users of proprietary cables (integral with sensors or actuators), these users should follow those manufacturers’ installation requirements. Mitsubishi Electric recommends that shielded cables be used. If NO other EMC protection is provided, users may experience temporary loss or accuracy between +10% / -10% in very heavy industrial areas. However, Mitsubishi Electric suggests that adequate EMC precautions be followed for the users complete control system.

 Sensitive analog cables should not be laid in the same trunking

or cable conduit as high voltage cabling. Where possible, users should run analog cables separately.

 Good cable shielding should be used. When terminating the shield

at Earth, ensure that no earth loops are accidentally created.

 When reading analog values, EMC accuracy can be improved

by averaging the readings. This can be achieved either through functions on the analog products or through a user’s program in the FX3GE Series PLC main unit.

4. SPECIFICATIONS AND WIRING

DANGER DESIGN PRECAUTIONS

• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during external power supply problems or PLC failure. Otherwise, malfunctions may cause serious accidents.

 Most importantly, have the following: an emergency stop circuit,

a protection circuit, an interlock circuit for opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the equipment at the upper and lower positioning limits).

 Note that when the PLC CPU detects an error, such as a

watchdog timer error, during self-diagnosis, all outputs are turned off. Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be disabled. External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

 Note that when an error occurs in a relay the output could be

held either on or off. For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe machinery operation in such a case.

• Do not bundle the control line together with or lay it close to the main circuit or power line. As a guideline, lay the control line at least 100mm (3.94") or more away from the main circuit or power line. Noise may cause malfunctions.

• Install module so that excessive force will not be applied to the builtin programming connectors, power connectors or I/O connectors. Failure to do so may result in wire damage/breakage or PLC failure.

• Even if the AC power supply causes an instantaneous power failure for less than 10 ms, the PLC can continue to operate.

• If a long-time power failure or an abnormal voltage drop occurs, the PLC stops, and output is turned off. When the power supply is restored, it will automatically restart (when the RUN input is on).

CAUTION WIRING PRECAUTIONS

• Connect the AC power supply to the dedicated terminals specified in this manual. If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will burn out.

• Do not wire vacant terminals externally. Doing so may damage the product.

• Use class D grounding (grounding resistance of 100Ω or less) with a wire of 2mm² or thicker on the grounding terminal of the FX3GE Series main unit. However, do not connect the ground terminal at the same point as a heavy electrical system.

• When drilling screw holes or wiring, make sure cutting or wire debris does not enter the ventilation slits. Failure to do so may cause fire, equipment failures or malfunctions.

• Make sure to properly wire to the terminal in accordance with the following precautions. Failure to do so may cause electric shock, equipment failures, a short-circuit, wire breakage, malfunctions, or damage to the product.

 The disposal size of the cable end should follow the dimensions

described in the manual.

 Tightening torque should follow the specifications in the manual.

• Input/output wiring 50 to 100m (164'1" to 328'1") long will cause almost no problems of noise, but, generally, the wiring length should be less than 20m (65'7") to ensure the safety.

4.1 WIRING

n CABLE END TREATMENT AND TIGHTENING TORQUE

• For the terminals of FX3GE series PLC, M3 screws are used. The electric wire ends should be treated as shown below.

• Tighten the screws to a torque of 0.5 to 0.8 N•m.

• Do not tighten terminal screws with a torque exceeding the regulation torque.

• Failure to do so may cause equipment failures or malfunctions.

n INSTRUCTIONS FOR CONNECTING INPUT DEVICES In the case of no-voltage contact The input current of this PLC is

5 to 7mA/24VDC. Use input devices applicable to this current. If no-voltage contacts (switches) for large current are used, contact failure may occur.

In the case of input device with built-in series diode The voltage drop of the series diode should be approx. 4V or less. When lead switches with a series LED are used, up to two switches can be connected in series. Also make sure that the input current is over the input-sensing level while the switches are ON.

In the case of input device with built-in parallel resistance Use a device with a parallel resistance of 15kΩ or more. When the resistance is less than 15kΩ, connect a bleeder resistance.

In the case of 2-wire proximity switch Use a two-wire proximity switch whose leakage current is 1.5mA or less when the switch is off. When the current is 1.5mA or more, connect a bleeder resistance.
