HANDLING AND INSTALLATION
37

The cabinet must be installed in a location from which you can easily inspect it when the door is open.

The cabinet must be installed at least 500mm from the nearest wall to allow maintenance access.
12.4. Connection
WARNING
！
The system must be grounded. Failure to ground equipment may result in injury from fire or electric
shock.
Before grounding the system, turn off the power supply and lock the main power switch. Failure to
observe this caution may result in injury and electric shock.
Do not touch any unit inside the controller for five minutes after turning off the power supply.
Capacitors inside the controller store electricity after power is turned off. Exercise caution whenever
handling circuit boards. Failure to observe this caution may cause electric shock.
Power cannot be turned on unless the door is closed. Interlocks prevent power from being turned on.
Failure to observe this caution may result in fire and electric shock.
Any occurrence during wiring while the cabinet is in the emergency stop mode is the user’s
responsibility. Do an operation check once the wiring is completed. Failure to observe this caution
could lead to injury or mechanical failure.
CAUTION
！
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 Manuals. 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.
12.4.1. Notes on Cable Junctions
The cables that connect the controller to peripheral device 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
cabled 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 damage. One connects the manipulator
and the cabinet. Another connects the cabinet and peripheral device. 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.
