Mitsubishi Electric RV-4FM-SE Series Instruction Manual page 5

WARNING
When the robot arm has to be moved by hand from an external area, do not
place hands or fingers in the openings. Failure to observe this could lead to
hands or fingers catching depending on the posture.
CAUTION
Do not stop the robot or apply emergency stop by turning the robot controller's
main power OFF. If the robot controller main power is turned OFF during
automatic operation, the robot accuracy could be adversely affected. Moreover,
it may interfere with the peripheral device by drop or move by inertia of the arm.
CAUTION
Do not turn off the main power to the robot controller while rewriting the
internal information of the robot controller such as the program or parameters.
If the main power to the robot controller is turned off while in automatic
operation or rewriting the program or parameters, the internal information of the
robot controller may be damaged.
DANGER
Do not connect the Handy GOT when using the GOT direct connection function
of this product. Failure to observe this may result in property damage or bodily
injury because the Handy GOT can automatically operate the robot regardless
of whether the operation rights are enabled or not.
DANGER
Do not remove the SSCNET III cable while power is supplied to the controller.
Do not look directly at light emitted from the tip of SSCNET III connectors or
SSCNET III cables. Eye discomfort may be felt if exposed to the light.
(Reference: SSCNET III employs a Class 1 or equivalent light source as
specified in JIS C 6802 and IEC60825-1 (domestic standards in Japan).)
DANGER
Attach the cap to the SSCNET III connector after disconnecting the SSCNET
III cable. If the cap is not attached, dirt or dust may adhere to the connector
pins, resulting in deterioration connector properties, and leading to malfunction.
CAUTION
Make sure there are no mistakes in the wiring. Connecting differently to the way
specified in the manual can result in errors, such as the emergency stop not
being released. In order to prevent errors occurring, please be sure to check
that all functions (such as the teaching box emergency stop, customer emer -
gency stop, and door switch) are working properly after the wiring setup is com -
pleted.
CAUTION
Use the network equipments (personal computer, USB hub, LAN hub, etc)
confirmed by manufacturer. The thing unsuitable for the FA environment
(related with conformity, temperature or noise) exists in the equipments
connected to USB. When using network equipment, measures against the noise,
such as measures against EMI and the addition of the ferrite core, may be
necessary. Please fully confirm the operation by customer. Guarantee and
maintenance of the equipment on the market (usual office automation
equipment) cannot be performed.
