Before installing or operating the Manipulator, make sure that no parts of the Manipulator are missing and that it has no damage or other external defects. Missing parts or damage may cause malfunction of the Manipulator, is extremely hazardous, and may result in serious injury to operators and/or severe equipment damage.
Do not use the Manipulator near devices that generate strong magnetic forces. This may cause Manipulator failure or malfunction.
Do not use the Manipulator in areas where there is a risk of electromagnetic interference, electrostatic discharge, or radio frequency interference. This is dangerous because the Manipulator may malfunction.
Do not use the Manipulator where it is exposed to combustible gases, combustible dusts, gasoline, solvents, or other flammable liquids that may cause an explosion or fire. This may cause serious accidents involving injury or death as well as fires.
Keep hands and other objects away from moving parts of the Manipulator. There is a risk of injury due to pinching.
Do not install the Controller upside down or at an angle.
For protected-model
Connect the power cable connector and the signal cable connector to the connector plate immediately after installing the Manipulator. When the Manipulator is unconnected, protection at IP65 cannot be ensured.
This may result in electric shock and/or malfunction of the robot system.
If the Manipulator is installed on a movable platform ( linear axis, movable cart, AGV, etc.), be sure to design the system so that the movable platform also stops when the Manipulator is stopped in an emergency. If the movable platform continues to operate without stopping, it is extremely hazardous and may result in serious injury to operators and/or severe damage.
WARNING
Always use a power plug or a disconnecting device for the power cable, and never connect directly to the factory power supply or the like.
Do not open the cover of the Controller or Manipulator except during maintenance. There is a high-voltage charging section inside, and there is a risk of electric shock even when the power is turned off.
Be sure to turn off the power to the robot system before connecting or disconnecting cables. Working with the power on may result in electric shock and/or malfunction of the robot system.
Use cables with securely protected high-voltage sections and connect them securely. Also, do not put heavy objects on the cables, bend them severely, pull them forcibly, or pinch them. Damaged cables, broken wires, or contact failure is extremely hazardous and may result in electric shock and/or malfunction of the robot system.
If installing a power plug to match a factory power socket, the installation should be performed by personnel with specialized knowledge and skills in the field. When installing the power plug, be sure to connect the ground wire (green/yellow) of the AC power cable to the ground terminal of the power distribution system. If the ground wire is improperly connected to ground, it may result in the electric shock.
Always use a circuit breaker for the Controller's power supply. Failure to use a circuit breaker may result in electric shock and/or malfunction of the robot system.
When connecting the Controller power supply to a transformer, connect the N and PE terminals of the AC power cable to the neutral terminal of the transformer.
Installation for options should be performed by people who have received maintenance training provided by Epson and the suppliers. Be sure to turn off the power to the robot system and disconnect the power cables during work. Working with the power on or with the high-voltage charging sections not fully discharged may result in electric shock and/or serious safety problems.
Remove the power plug when opening the front of the Controller. Touching the AC power input terminal block or other components inside the enclosure may result in electric shock and/or serious safety problems.
The Manipulator is grounded by connecting it to the Controller. Ensure that the Controller is grounded and the cables are correctly connected. If the ground wire is improperly connected to ground, it may result in the fire or electric shock.
Be sure to turn off the power and tag out (e.g., with a "DO NOT TURN ON" sign) before performing wiring. Performing any work procedure with the power turned on is extremely dangerous and may result in electric shock and/or malfunction of the robot system.
If there is a brake release unit and external short connector
Turn off the power to the Controller and brake release unit when connecting or replacing the brake release unit or external short connector. Inserting or removing connectors with the power on may result in electric shock and/or malfunction of the robot system.
Do not touch the terminals. Doing so may cause electric shock, product damage, or malfunction.
