A - 1 A - 1 SAFETY PRECAUTIONS (Read these precautions before using.) W hen using Mitsubishi equipment, thoroughly read this manual and the associat ed manuals introduced in this manual. Also pay careful att ention to safet y and handle t he module properly.
A - 2 A - 2 [DESIGN PRECAUTIONS] ! DANGER W hen overcurrent which exceeds the rating or caused by short-circuited load flows in t he output module for a long time, it may cause smoke or f ire. To prevent t his, configure an external safety circuit, such as fuse.
A - 3 A - 3 [INSTALLATION PRECAUTIONS] ! CAUTION Use the PLC in an environment t hat meets the general specifications cont ained in this manual. Using this PLC in an environment out side the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.
A - 4 A - 4 [WIRING PRECAUTIONS] ! CAUTION Be sure to ground the FG terminals and LG t erminals to the protectiv e ground conductor. Not doing so could result in electric shock or erroneous operation. W hen wiring in the PLC, be sure that it is done correctly by checking the product's rated v oltage and the terminal layout.
A - 5 A - 5 [STARTUP AND MAINTENANCE PRECAUTIONS] ! DANGER The online operations conducted for the CPU module being operated, connecting the peripheral device (especially , when changing dat a or operation stat us), shall be conducted after t he manual has been carefully read and a sufficient check of safety has been conducted.
