Specifications subject to change without notice. SAFETY PRECAUTIONS (Always read these instructions before the exercise.) When designing the system, always read the relevant manuals and give sufficient consideration to safety. During the exercise, pay full attention to the following points and handle the product correctly. [EXERCISE PRECAUTIONS] WARNING Do not touch the terminals while the power is on to prevent electric shock. When opening the safety cover, turn off the power or conduct a sufficient check of safety before operation. Caution Follow the instructor’s direction during the exercise. Do not remove the module of the demonstration machine or change wirings without permission. Doing so may cause failures, malfunctions, personal injuries and/or a fire. Turn off the power before installing or removing the module. Failure to do so may result in malfunctions of the module or electric shock. When the demonstration machine (X/Y table, etc.) emits abnormal odor/sound, press "Power switch" or "Emergency switch" to turn off. When a problem occurs, notify the instructor as soon as possible.
