No, if they are in one enclosure then they are one "device".
Don't forget once you go from simple systems into safety devices, emergency stops, guard switches, light curtains etc. then you are into full blown EN 13849 territory and that is required for compliance with the SMSR & PUWER, and anyone doing this work is encompassed into this legislation.

Thanks, I'm only curious as to what point a simple system stops being simple.

Don't worry Pete, I don't need educating, I was just trying to grasp what the bloke said as I couldn't understand it.

Once you have a safety function, so basically anything more than an e-stop, and more than the device count as specified in EN 60204-1.

Personally I just turn down any work which involves motor/machinery controls, but I do wish that at some point during my time at college someone had actually told us that these regulations even exist and told us what the average electrician can and cannot do without further training.

Grab a copy of 60204 Dave, it's relatively an easy read compared to the BYB.

I was under the impression it was a tad expensive?

 

[LeeH]

It makes 7671 look a bargain.

PM sent.

EN60204 is relitivly cheep, problem is going any deeper than the surface requires other standards like EN12100, E13849-1 & EN62061 being the main ones.

Looking at circa £550 for those 3 if you're not a BSI member.

 

[LeeH]

It's over 200 IIRC.

 

[Bobster]

60204 is £282 from BSi if you're not a member £141 if you are.
