mm diameter, which is being pressed with
the power of 3.1 kg±10%, from going through the opening in the outer sheath of the supplied equipment.
Refer to the section Page 152, "6.2 Working environment" for details on the working environment.
Note2) The power capacity is the rating value for normal operation. The power capacity does not include the rush current when
the power is turned ON. The power capacity is a guideline and the actual operation is affected by the input power volt

age. The power consumption in the specific operation pattern with the RH-3FH is approx. 0.3kW. The short circuit
breaker should use the following.
* Operate by the current leakage under the commercial frequency domain (50-60Hz). If sensitive to the high frequency
ingredient, it will become the cause in which below the maximum leak current value carries out the trip.
Note3) Refer to Page 69, "3.3.1 Outside dimensions" for details.
Note4) This controller is standard specification. (Refer to Page 64, "3.1.2 Protection specifications and operating supply".)
Note5) The robot must be grounded by the customer.
