CAUTION
• Tighten the terminal screws within the specifi ed torque range. A loose terminal
screw could lead to short-circuiting or malfunctioning. If the terminal screw is
too tight, short-circuiting or malfunctioning could occur due to screw damage.
• Make sure that foreign matter, such as cutting chips or wire scraps, do not enter
the robot controller.
• The communication cables connected to the CC-Link compatible module must
be placed in a conduit or fi xed with a clamp. If the cable is not placed in a
conduit or fi xed with a clamp, the module or cable could be damaged by the
cable shifting, movement or unintentional pulling leading to malfunctioning
caused by an improper cable connection.
• Do not disconnect the communication cable connected to the CC-Link
compatible module by pulling on the cable section. Loosen the screws on the
connector, and then disconnect the cable. Pulling on the cable fi xed with
screws could lead to module or cable damage, or malfunctioning caused by
an improper cable connection.
