STARTING INSTALLATION OR WIRING WORK. FAILURE TO SHUT OFF ALL
PHASES MAY CAUSE ELECTRICAL SHOCK OR PRODUCT DAMAGE.

CAUTION
• Make sure that no foreign matter such as cutting chips or wire scraps
enter the robot controller. Malfunctions, breakdown or fi re may result if
they have entered.
• Always store the cables connected to the robot controller in a conduit or
clamp them securely in place. If the cables are not stored in a conduit or
properly clamped, excessive play or movement or mistakenly pulling on
the cable may damage the connector or cables, and poor cable contact
may cause equipment malfunctions.
• Do not modify the cables and do not place any heavy object on them.
Handle them carefully to avoid damage. Damaged cables may cause
malfunction or electrical shock.
• If there is a possibility that the cables connected to the robot controller
may be damaged, protect them with a cover, etc.
• Do not apply excessive loads or impacts to the connectors when making
cable connections. The connector pins may become bent or the internal
PC board may be damaged.
• When disconnecting the cable from the robot controller, detach by
gripping the connector itself and not by tugging on the cable. Loosen the
screws on the connector (if fastened with the screws), and then
disconnect the cable. Detaching by pulling on the cable itself may
damage the connector or cables, and poor cable contact may cause
equipment malfunctions.
