3.1.2 Protection specifications and operating supply

A protection method complying with the IEC Standard IP20 (Opened type) is adopted for the controller.

The IEC IP symbols refer only to the degree of protection between the solid and the fluids, and don't indicated 
that any special protection has been constructed for the prevention against oil and water.

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 

 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.
