Safety Precautions 3

•Do not apply voltages or connect loads to the built-in outputs in excess of the maximum switching capacity. Excess voltage or loads may result in burning.

•Disconnect the functional ground terminal when performing withstand voltage tests. Not disconnecting the functional ground terminal may result in burning.

•Wire correctly and double-check all the wiring or the setting switches before turning ON the power supply. Incorrect wiring may result in burn- ing.

•Check that the DIP switches and data memory (DM) are properly set before starting operation.

•Check the user program for proper execution before actually running it on the Module. Not checking the program may result in an unexpected oper- ation.

•Resume operation only after transferring to the new Module the contents of the DM Areas, programs, parameters, and data required for resuming operation. Not doing so may result in an unexpected operation.

•Do not pull on the cables or bend the cables beyond their natural limit. Doing either of these may break the cables.

•Do not place objects on top of the cables. Doing so may break the cables.

•Use the dedicated connecting cables specified in operation manuals to connect the Modules. Using commercially available RS-232C computer cables may cause failures in external devices or the Coordinator Module.

•Do not connect pin 6 (+5V) on the RS-232C port on the Coordinator Mod- ule to any external device other than the NT-AL001 or CJ1W-CIF11 Con- version Adapter. Doing so may result in damage to the external device and the Coordinator Module.

•When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may result in malfunction or burning.

•When transporting or storing the product, cover the PCBs with electrically conductive materials to prevent LSIs and ICs from being damaged by static electricity, and also keep the product within the specified storage temperature range.

•Do not touch the mounted parts or the rear surface of PCBs because PCBs have sharp edges such as electrical leads.

•When connecting the Power Supply Unit, Coordinator Module, Motion Control Module, and End Module, slide the upper and lower sliders until a click sound is heard to lock them securely. Desired functionality may not be achieved unless Modules are securely locked in place.

•Be sure to mount the End Module supplied with the Coordinator Module to the rightmost Module. Unless the End Module is properly mounted, the FQM1 will not function properly.

•Make sure that parameters are set correctly. Incorrect parameter settings may result in unexpected operations. Make sure that equipment will not be adversely affected by the parameter settings before starting or stop- ping the FQM1.
