The following items are safety precautions for qualified design or installation
personnel: (cont.)
WARNING

Do not open the cover(s) of the Controller except while maintaining it. Opening
the cover(s) of the Controller is extremely hazardous and may result in electric
shock even when its main power is OFF because of the high voltage charge
inside the Controller.

Make sure that the power to the Controller is turned OFF before connecting or
disconnecting any cables. Connecting or disconnecting any cables with the
power ON is extremely hazardous and may result in electric shock and/or
malfunction of the Controller.

Be sure to connect the cables properly. Do not allow unnecessary strain on the
cables. (Do not put heavy objects on the cables. Do not bend or pull the cables
forcibly.) The unnecessary strain on the cables may result in damage to the
cables, disconnection, and/or contact failure. Damaged cables, disconnection,
or a contact failure is extremely hazardous and may result in electric shock and/or
improper function of the system.

When connecting the plug to fit the outlet in your factory, make sure that it is done
by qualified personnel. When connecting the plug, be sure to connect the earth
wire of the AC power cable colored green/yellow on the Controller to the earth
terminal of the factory power supply. The equipment must be grounded properly
at all times to avoid the risk of electric shock. Always use a power plug and
receptacle. Never connect the Controller directly to the factory power supply.
(Field wiring)
CAUTION

The serial number of the Manipulator that should be connected is indicated on the
Connection Check Label on the Controller. Connect the Controller and the
Manipulator correctly. Improper connection between the Controller and the
Manipulator may cause improper function of the robot system and also safety
problems.

When using remote I/O, always make sure of the following. Using the robot
system under unsatisfactory conditions may cause malfunction of the system
and/or safety problems.
- Assign remote functions to inputs/outputs correctly and wire correctly when
setting up remote I/O signals.
- Make sure that the functions correspond to the correct input/output signals
before turning ON the system.
- When verifying the robot system operation, prepare for failures with initial
settings or wiring. If the Manipulator functions unusually by the failures with
initial settings or wiring, press the Emergency Stop switch immediately to stop
the Manipulator.
