CKD ERL 2-45, Руководство пользователя, Страница: 56 / 64

This product is designed and manufactured as a general industrial machine part.
Therefore, it must be handled by an operator with sufficient knowledge and experience.
Use the product within the specifications range.
This product must be used within its stated specifications. In addition, never modify or additionally machine this
product.
This product is intended for use in general industrial machinery equipment or parts. It is not intended for use outdoors
or for use under the following conditions or environments.
(Note that this product can be used when CKD is consulted prior to its usage and the customer consents to the CKD
product specifications. The customer should provide safety measures to avoid danger in the event of problems.)
Use in applications which require safety such as nuclear energy, railways, aircraft, marine vessels, vehicles,
medicinal devices, devices or applications that come into contact with beverages or foodstuffs, amusement
devices, emergency operation (shutoff, release, etc.) circuits, press machines, brake circuits, or other safety
devices and applications.
Use for applications where life or assets could be significantly affected, and special safety measures are required.
Observe organizational standards and legal regulations, etc., pertaining to the safety of equipment
design.
Do not remove any devices before checking the safety.
Inspect and service the machine and devices after confirming the safety of the entire system related to this
product.
Note that there may be hot or charged sections even after operation is stopped.
When inspecting or servicing the device, shut off the equipment power supply and the power supply of the
corresponding facility, discharge any compressed air from the system, and beware of electric shock.
Observe the warnings and cautions in the instruction manuals for each product to prevent accidents.
Unexpected operations may occur during teaching work and test operation stage, so be sure not to touch the
actuator. When operating from a position where the actual axis cannot be seen, be sure it is safe for the actuator
move before operating.
Be sure to observe the warnings to prevent electric shock.
Do not touch the heat sink, cement resistor, and motor inside the controller.
These parts are very hot and may cause burns. Perform inspection tasks after waiting a sufficient amount of time.
Immediately after the power supply is turned off, a high voltage is applied to the internal capacitor until the built-up
electrical charge is discharged, so do not touch it for about three minutes.
Turn off the switch which provides the controller power supply before performing maintenance and inspection.
There is a risk of electric shock due to high voltage.
Do not attach or remove any connectors with the power supply turned on. Doing so may risk malfunction, failure,
and electric shock.

WARNING
When designing equipment using electric actuators, there is an obligation to check that the safety of the system,
which is operated according to the equipment's machine mechanism and the electric control, can be ensured and to
manufacture safe equipment.
It is important to select, use, handle, and maintain CKD products appropriately to ensure their safe usage.
Observe warnings and precautions to ensure device safety.
Check that device safety is ensured, and manufacture a safe device.

Install an overcurrent protection device.
The wiring to the controller should comply with the JIS B 9960-1:2008 Safety of Machinery - Electrical Equipment of
Machines - Part 1: General Requirements. Install an upstream overcurrent protection device (a shutoff mechanism or
circuit protector for wiring) for the drive (power supply connector, common power supply terminal block) and the control
(input-output connectors) power supply.
(Excerpted from "JIS B 9960-1 7.2.1 General Information")
If there is a possibility that the circuit current within the machinery (electrical equipment) may exceed the smaller of
the rated value of the components or the allowable current capacity, overcurrent protection must be installed. The
rated value or the set value which must be selected is provided in 7.2.10.
Observe the following precautions to prevent accidents.
