SAFETY PRECAUTIONS (Read these precautions before using.) When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in this manual. Also pay careful attention to safety and handle the module properly. These SAFETY PRECAUTIONS classify the safety precautions into two categories: "DANGER" and "CAUTION". DANGER Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
[DESIGN PRECAUTIONS] ! DANGER When overcurrent which exceeds the rating or caused by short-circuited load flows in the output module for a long time, it may cause smoke or fire. To prevent this, configure an external safety circuit, such as fuse. Build a circuit that turns on the external power supply when the PLC main module power is turned on. If the external power supply is turned on first, it could result in erroneous output or erroneous operation.
[INSTALLATION PRECAUTIONS] ! CAUTION Use the PLC in an environment that meets the general specifications contained in this manual. Using this PLC in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product. Hold down the module loading lever at the module bottom, and securely insert the module fixing latch into the fixing hole in the base unit.
[WIRING PRECAUTIONS] ! CAUTION Be sure to ground the FG terminals and LG terminals to the protective ground conductor. Not doing so could result in electric shock or erroneous operation. When wiring in the PLC, be sure that it is done correctly by checking the product's rated voltage and the terminal layout. Connecting a power supply that is different from the rating or incorrectly wiring the product could result in fire or damage.
[STARTUP AND MAINTENANCE PRECAUTIONS] ! DANGER The online operations conducted for the CPU module being operated, connecting the peripheral device (especially, when changing data or operation status), shall be conducted after the manual has been carefully read and a sufficient check of safety has been conducted. Operation mistakes could cause damage or problems with of the module. Do not disassemble or modify the modules. Doing so could cause trouble, erroneous operation, injury, or fire.

8 EMC AND LOW VOLTAGE DIRECTIVE MELSEC-Q 8.1.2 Installation instructions for EMC Directive The PLC is open equipment and must be installed within a control cabinet for use. This not only ensures safety but also ensures effective shielding of PLC-generated electromagnetic noise. (1) Control cabinet (a) Use a conductive control cabinet. (b) When attaching the control cabinet's top plate or base plate, mask painting and weld so that good surface contact can be made between the cabinet and plate.
8 EMC AND LOW VOLTAGE DIRECTIVE MELSEC-Q 8.1.3 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 cable 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. The use of a shielded cable also increases noise resistance.
8 EMC AND LOW VOLTAGE DIRECTIVE MELSEC-Q (2) MELSECNET/H module Always use a double-shielded coaxial cable (MITSUBISHI CABLE INDUSTRIES, LTD.: 5C-2V-CCY) for the coaxial cables MELSECNET/H module.
