Class 2 question

I have a 1/16 DIN display that is powered by 120V. it has a class 2/or may be 1(has a shielded cable) encoder that connects right near the 120V on back of the display,The encoder cable runs a few feet out of the display box to a turning wheel to display speed. That is having the 120 and class 2 pretty close together,is that ok? how else could this be accomplished.

Not understanding your question. If this display is a manufactured assembly then where the 120V line cord and the LV encoder cable is is of no concern to you. It's been listed and approved.

Does this have something to do with your other question about installing a display in a box?

Thank you hbiss, Yes that is what I was asking, And I agree it was made this way, how else would you be able to use it.I am not sure that everything available is listed and approved. This one probably is, So in reading art:725 it would seem I have to make sure the line voltage and the class 2 need to be 1/4 inch apart from each other.

CONDUCTORS need to be at least 1/4" apart. NOT THE CABLES coming out of the thing! You are not going to be dealing with conductors unless you open the thing up.

725 doesn't apply to you!

I am assuming that the encoder cable is field connected to the device, and the spacing inside the device must be maintained as required in 725 when making the field connections.
