scope:
This s ection of IEC 60947-5 provides detailed specifications relating t o the electrical and mechanical construction of emergency stop devices with mechanical latching function and to their testing.
his standard is applicable to electrical c ontrol circuit devices and switching elements which are used to initiate an emergency stop signal. Such devices may be either provided with their own enclosure, or installed according to the manufacturer's instructions.
This standard does not apply to:
- emergency stop devices for non-electrical control circuit, for example hydraulic, pneumatic;
- emergency stop devices without mechanical latching function.
An stop device may also be used to provide an emergency switching off function
This standard does not deal with any specific requirements on noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard.
NOTE See also 9.2.5.4 of IEC 60204-1:2005.
This European Standard does not deal with any specific requirements on noise as the noise emission of electrical emergency stop devices with mechanical latching function is not considered to be a relevant hazard.
