8.2.1 of 60204-1 states that:
The protective bonding circuit consists of:
- PE terminal(s) (see 5.2);
- the protective conductors in the equipment of the machine including sliding contacts
where they are part of the circuit;
- the exposed conductive parts and conductive structural parts of the electrical equipment;
- those extraneous conductive parts which form the structure of the machine.
The last bullet point seems to answer your question.
Is a "panel" an "extraneous conductive part", given the definition in EN60204-1 which is as follows:
conductive part not forming part of the electrical installation and liable to introduce a potential, generally the earth potential
(which is very similar if not the same to BS7671)?
I'm not sure a panel on
the machine can, under general circumstances, introduce a potential from outside
the machine (or even the installation) ?
Of course, that doesn't mean the panel shouldn't be bonded for EMC purposes!
