4.1 Notes on Cable Junctions
• The cables that connect the controller to peripheral equipment are low voltage circuits.
Keep controller signal cables away from the primary power circuit. High voltage power
lines should not be run in parallel to controller signal cables. If running parallel cables is
unavoidable, use metal ducts or conduit to isolate electrical signal interference. If cables
must be crossed, run the power cables perpendicular across the signal cables.
• Confirm the connector and cable numbers to prevent misconnection and equipment dam-
age. One connects the manipulator and XRC. Another connects the XRC and peripheral
equipment. A wrong connection can cause damage to electronic equipment.
• Clear the area of all unauthorized personnel while making cable connections. Place all
cables in a covered cable channel in the floor.
• Wiring must be performed only by authorized personnel.
Incorrect wiring may cause fire and electric shock.
• Perform wiring in accordance with the rated capacity as specified in
the Instructions.
Incorrect wiring may cause fire or mechanical breakdown.
• Be sure the power circuit screws are securely tightened.
Loose power circuit wires can cause fire and electric shock.
• Do not handle the circuit board directly by hand.
The IC board may malfunction due to static electricity.
