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.
