Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. In this manual, the safety precautions are classified into two levels: "...
  • Page 4 [DESIGN PRECAUTIONS] WARNING (2) When the programmable controller detects the following error conditions, it stops the operation and turn off all the outputs. • The overcurrent protection device or overvoltage protection device of the power supply module is activated. • The programmable controller CPU detects an error such as a watchdog timer error by the self-diagnostics function.
  • Page 5 [DESIGN PRECAUTIONS] WARNING When controlling a running programmable controller (data modification) by connecting a peripheral device to the CPU module or a PC to a special function module, create an interlock circuit on sequence programs so that the whole system functions safely all the time. Also, before performing any other controls (e.g.
  • Page 6 CAUTION Do not install the control lines or communication cables together with the main circuit or power lines, or bring them close to each other. Keep a distance of 100mm (3.94inch) or more between them. Failure to do so may cause malfunctions due to noise. When an output module is used to control the lamp load, heater, solenoid valve, etc., a large current (ten times larger than the normal one) may flow at the time that the output status changes from OFF to ON.
  • Page 7 [INSTALLATION PRECAUTIONS] CAUTION Use the programmable controller under the environment specified in the user’s manual. Otherwise, it may cause electric shocks, fires, malfunctions, product deterioration or damage. Insert the module fixing projection into the fixing hole in the base unit and then tighten the module mounting screw within the specified torque.
  • Page 8 [WIRING PRECAUTIONS] WARNING Be sure to shut off all phases of the external power supply used by the system before wiring. Failure to do so may result in an electric shock or damage of the product. Before energizing and operating the system after wiring, be sure to attach the terminal cover supplied with the product.
  • Page 9 [STARTUP AND MAINTENANCE PRECAUTIONS] WARNING Do not touch any terminal during power distribution. Doing so may cause an electric shock. Properly connect batteries. Do not charge, disassemble, heat or throw them into the fire and do not make them short-circuited and soldered. Incorrect battery handling may cause personal injuries or a fire due to exothermic heat, burst and/or ignition.

    3.1.2 Installation instructions for EMC Directive The programmable controller is open equipment and must be installed within a control cabinet for use.* This not only ensures safety but also ensues effective shielding of programmable controller-generated electromagnetic noise. Also, each network remote station needs to be installed inside the control panel.

(a) Provide an earthing point near the power supply module. Earth the power supply's LG and FG terminals (LG : Line Ground, FG : Frame Ground) with the thickest and shortest wire possible.

  • Page 38: Cables

    3.1.3 Cables The cables extracted from the control panel contain a high frequency noise component. On the outside of the control panel, therefore, they serve as antennas to emit noise. To prevent noise emission, use shielded cables for the cables which are connected to the I/O modules and intelligent function modules and may be extracted to the outside of the control panel.
  • Page 39 A1SJ71AR21, A1SJ71LR21 and A1SJ71BR11. Noise in the range of 30 MHz or higher in radiation noise can be suppressed by the use of double-shielded coaxial cables (manufactured by MITSUBISHI CABLE INDUSTRIES, LTD: 5C-2V-CCY). Earth the outer shield to the ground.

(8) Measures against static electricity When using an insulation displacement connector without connector cover, a connected cable for the connector is thin in applicable wire size and coating.

  • Page 45: Ferrite Core

    3.1.5 Ferrite core Use of ferrite cores is effective in reducing the conduction noise in the band of about 10 MHz and radiated noise in 30 to 100 MHz band. It is recommended to attach ferrite cores when the shield of the shielded cable coming out of the control panel does not work effectively, or when emission of the conduction noise from the power line has to be suppressed.

  • Page 48: Requirements For Compliance With Low Voltage Directives

    3.2 Requirements for Compliance with Low Voltage Directives The Low Voltage Directives apply to the electrical equipment operating from 50 to 1000VAC or 75 to 1500VDC; the manufacturer must ensure the adequate safety of the equipment. Guidelines for installation and wiring of MELSEC-AnS series programmable controller are provided in Section 3.2.1 to 3.2.7 for the purpose of compliance with the EMC Directives.
  • Page 49 (2) I/O module For I/O module with rated input voltage of 100/200 VAC, select a model in which the internal area between the first order and second order is intensively insulated, because it has hazardous voltage area. For I/O module with 24 VDC rated input, a conventional model can be used.

  • Page 50: Power Supply

    3.2.3 Power supply The insulation specification of the power module was designed assuming installation category II. Be sure to use the installation category II power supply to the programmable controller. The installation category indicates the durability level against surge voltage generated by a thunderbolt. Category I has the lowest durability; category IV has the highest durability.
  • Page 51 (2) Dustproof and waterproof features The control panel also has the dustproof and waterproof functions. Insufficient dustproof and waterproof features lower the insulation withstand voltage, resulting in insulation destruction. The insulation in our programmable controller is designed to cope with the pollution level 2, so use in an environment with pollution level 2 or below.

  • Page 52: Module Installation

    3.2.5 Module installation (1) Installing modules contiguously In QAnS series programmable controllers, the left side of each I/O module is left open. When installing an I/O module to the base, do not make any open slots between any two modules. If there is an open slot on the left side of a module with 100/200 VAC rating, the printed board which contains the hazardous voltage circuit becomes bare.

    (6) When installing the base unit to DIN rail in an environment with large vibration, use a vibration-proofing bracket (A1S-PLT-D). Mounting the vibration-proofing bracket (A1S-PLT-D) enhances the resistance to vibration. Depending on the environment to set up the base unit, it is also recommended to fix the base unit to the control panel directly.

  • Page 61 In such cases, all I/O points turn ON or OFF depending on the problem, and normal operation and safety cannot be maintained. Though Mitsubishi programmable controllers are manufactured under strict quality control, they may fail or malfunction due to unspecified reasons. To prevent the whole system failure, machine breakdown, and accidents, build a fail-safe circuit outside the programmable controller.
  • Page 62 Since YB0 turns ON and OFF alternatively at 0.5 second intervals, use a contactless output module (a transistor is used in the above example). If an offdelay timer (especially miniature timer) is not available, construct the failsafe circuit using an ondelay timer shown on the next page.
