MODEL AJ71LP21GE-U-E MODEL 13J813 CODE IB(NA)-66590-D(0706)MEE ©1996 MITSUBISHI ELECTRIC CORPORATION z SAFETY PRECAUTIONS z (Always read before starting use.) Before using this product, please read this manual and the relevant manuals introduced in this manual carefully and pay full attention to safety to handle the product correctly. The instructions given in this manual are concerned with this product. For the safety instructions of the programmable controller system, please read the CPU module user's manual. In this manual, the safety instructions are ranked as "DANGER" and "CAUTION". DANGER CAUTION Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury. Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage. Note that the CAUTION level may lead to a serious consequence according to the circumstances. Always follow the instructions of both levels because they are important to personal safety. Please store this manual in a safe place and make it accessible when required. Always forward it to the end user. [INSTALLATION PRECAUTIONS] CAUTION z Use the programmable controller in an environment that meets the general specifications contained in CPU module user’s manual. Using this programmable controller 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. z Fully insert the projection on the bottom of the module into the hole in the base unit and press the module into position. Not installing the module correctly could result in malfunction, damage, or drop of some pieces of the product. If using the product in a vibratory environment, tighten the module with the screws. Always tighten the module fixing screws within the specified torque range. Loose tightening could result in drop of some pieces of the product, short-circuit, and malfunction. Tightening the screws too much could result in drop of some pieces of the product, short-circuit, or malfunction due to the breakage of a screw or the module. [INSTALLATION PRECAUTIONS] CAUTION z Do not directly touch the printed circuit board, the conducting parts and electronic parts of the module. It may cause damage or erroneous operation. z Before handling the module, touch a grounded metal object to discharge the static electricity from the human body. Failure to do so may cause malfunction or failure of the module. z Completely turn off the externally supplied power used in the system before mounting or removing the module. Not doing so could result in damage to the product. [WIRING PRECAUTIONS] DANGER z Before wiring, be sure to shut off all phases of the external power supply used by the system. Failure to do so may cause electric shocks or damage the product. CAUTION z Be sure there are no foreign substances such as sawdust or wiring debris inside the module. Such debris could cause fires, damage, or erroneous operation. z Make sure to place the communication and power cables into a duct or fasten them using a clamp. Cables not placed in the duct or not clamped may hang or shift, allowing them to be accidentally pulled, which may cause a module malfunction and cable damage. z When removing the communication cable or power cables from the module, do not pull the cable. When removing the cable with a connector, hold the connector on the side that is connected to the module. When removing the cable connected to the terminal block, first loosen the screws on the terminal block. Pulling the cable that is still connected to the module may cause malfunction or damage to the module or cable. About the Manuals The following product manuals are available.

Wiring 5.1 Precautions for Laying Optical Fiber Cables (1) When connecting an optical fiber cable, the following restrictions on the bending radius must be observed. Make sure of the specifications of the cable to be used. (2) The optical fiber cable is wired in the following manner. There is no problem even if not wiring in order of the station number. There is no problem even if station how many become control station.

If oil from the hands, dirt or dust should adhere to the core, the transmission loss will increase, causing a malfunction in the data link. Also, do not remove the cover from the module connector until an optical fiber cable is connected. (4) When attaching or detaching the optical fiber cable to/from the module, hold the cable connector securely with the hands. (5) Connect the cable connector and module connector securely until you hear a "click" sound. (6) Please wire IN/OUT of the connector for the cable correctly. Please do loopback test, the set confirmation test, and the bureau order confirmation test after wiring. It might be generated that a baton abnormal passing cannot be generated when miswiring and the downed bureau which cannot do the loopback of an arbitrary bureau do the row again even by the reclosing of the power supply. (7) Completely turn off the externally supplied power used in the system when connecting or disconnecting the cable. 2 (0.08) 5 (0.20) 6.
