Safety precautions
NO. Task Precautions
z
Securely connect the cable connectors in a manner
free
from disconnection or looseness.
Failure to do so may result in fire, electric shock or product malfunction.
z
Do not cut and reconnect the cables of the product to extend or shorten the cables. Doing
so may result in fire or product malfunction.
(3) Grounding
z
Be sure to provide class D (former class 3) grounding for the controller. Grounding is
required to prevent electric shock and electrostatic charges, improve noise resistance and
suppress unnecessary electromagnetic radiation.
4 Installation/startup
(4) Safety measures
z
Implement safety measures (such as installing safety fences, etc.) to prevent entry into the
movement range of the robot when the product is moving or can be moved. Contacting the
moving robot may result in death or serious injury.
z
Be sure to provide an emergency stop circuit so that the product can be stopped
immediately in case of emergency during operation.
z
Implement safety measures so that the product cannot be started only by turning on the
power. If the product starts suddenly, injury or product damage may result.
z
Implement safety measures so that the product will not start upon cancellation of an
emergency stop or recovery of power following a power outage. Failure to do so may result
in injury, equipment damage, etc.
z
Put up a sign saying “WORK IN PROGRESS. DO NOT TURN ON POWER,” etc., during
installation, adjustment, etc. If the power is accidently turned on, electric shock or injury
may result.
z
Implement measures to prevent the loads, etc., from dropping due to a power outage or
emergency stop.
z
Ensure safety by wearing protective gloves, protective goggles and/or safety shoes, as
necessary.
z
Do not insert fingers and objects into openings in the product. Doing so may result in injury,
electric shock, product damage, fire, etc.
5 Teaching
z
Whenever possible, perform teaching from outside the safety fences. If teaching must be
performed inside the safety fences, prepare “work rules” and make sure the operator
understands the procedures thoroughly.
z
When working inside the safety fences, the operator should carry a handy emergency stop
switch so that the operation can be stopped any time when an abnormality occurs.
z
When working inside the safety fences, appoint a safety watcher in addition to the operator
so that the operation can be stopped any time when an abnormality occurs. The safety
watcher must also make sure the switches are not operated inadvertently by a third party.
z
Put up a sign saying “WORK IN PROGRESS” in a conspicuous location.
* Safety fences --- Indicate the movement range if safety fences are not provided.
6 Confirmation
operation
z
After teaching or programming, carry out step-by-step confirmation operation before
switching to automatic operation.
z
When carrying out confirmation operation inside the safety fences, follow the specified work
procedure just like during teaching.
z
When confirming the program operation, use the safety speed. Failure to do so may result
in an unexpected movement due to programming errors, etc., causing injury.
z
Do not touch the terminal blocks and various setting switches while the power is supplied.
Touching these parts may result in electric shock or malfunction.
