|Publication Date:||25 May 2008|
|ICS Code (Electrical engineering in general):||29.020|
|ICS Code (Safety of machinery):||13.110|
This Standard specifies the requirements and recommendations to achieve the following matters relating to the electrical equipment of machines.
- Safety of persons and property
- Consistency of control response
- Ease of maintenance
This Standard applies to the electrical, electronic and programmable electronic equipment and systems to machines not portable by hand while working including a group of machines working together in a co-ordinated manner.
NOTE 1 This Standard is an application standard for technology and is not intended to limit or inhibit technological advancement.
NOTE 2 In this Standard, the term "electrical" includes electrical, electronic and programmable electronic matters (i.e. the electrical equipment includes electrical, electronic and programmable electronic equipment).
NOTE 3 In this Standard, the term "person" refers to any individual and includes those persons who are assigned and instructed by the user or his agent(s) in the use and care of the machine in question.
The equipment covered by this Standard commences at the connecting point of the machine (see 5.1)
NOTE 4 The requirements for the power supply facility in buildings are specified in JIS C 60364 series.
This Standard is applicable to the electrical equipment that operates with nominal power supply voltage of 1 000 V or under for alternate current (a.c.) and of 1 500 V or under for direct current (d.c.) and with nominal frequencies of 200 Hz or under. power supply to the electrical equipment of the machine (see 5.1).
NOTE 5 For higher voltages, requirements are specified in JIS B 9960-11.
This Standard does not cover all the requirements (for example, guarding, interlocking or control) that are needed or required by other standards or regulations in order to protect persons from hazards other than electrical hazards. Each type of machine has unique requirements to be accommodated to provide adequate safety.
The scope of this Standard specifically includes the electrical equipment of machines as defined in 3.35, but is not limited to.
NOTE 6 Annex C lists examples of machines using the electrical equipment to which this Standard is applicable.
This Standard does not specify additional and special requirements that can apply to the electrical equipment of machines exemplified as follows.
- That are intended for use in open air (i.e. outside building or other protective structures)
- That use, process, or produce potentially explosive material (for example, paint or swarf)
- That are intended for use in potentially explosive or flammable atmosphere
- That have special risks when producing or using certain materials
- That are intended for use in mines
- Sewing machines, units and systems (specified in JIS B 9960-31)
- Hoisting machines (specified in JIS B 9960-32)
Power circuits where electrical energy is directly used as a working tool are excluded from this Standard.
NOTE 7 The International Standard corresponding to this Standard is as follows.
IEC 60204-1 : 2005 Safety of machinery-Electrical
In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21.
