  • Page 61: Precautions For Use

    13.3 Precautions for Use Warning (1) Do not touch the motor while in operation. The surface temperature of the motor can increase to approx. 90 C to 100 C due to operating conditions. Energizing alone may also cause this temperature increase. As it may cause burns, do not touch the motor when in operation.

  • Page 62: Operating Environment

    [Ground] Warning (1) Be sure to ground the electric actuator. (2) Grounding should be dedicated ground. Ground construction is Class D grounding. (Ground resistance 100 Ω or less) (3) Make the grounding as close as possible to the electric actuator and shorten the distance to ground.

  • Page 63: Maintenance

    13.5 Maintenance Warning (1) Do not disassemble or repair the product. Fire or electric shock can result. (2) Before modifying or checking the wiring, the voltage should be checked with a tester 5 minutes after the power supply is turned off. Electrical shock can result.

  • Page 64: Controller And Its Peripheral Devices /Specific Product Precautions

    (7) When the electric actuator is operated manually (when SVRE output signal is off), supply 24 VDC to the [BK RLS] terminal of the power supply connector. If the product is operated without releasing the lock, wearing of the lock sliding surface will be accelerated, causing reduction in the holding force and the life of the locking mechanism.

  • Page 65: Installation

    Check the voltage using a tester for more than 5 minute after power-off in case of installation, wiring and maintenance. There is a possibility of getting electric shock, fire and injury.
