Wiring is the mode of communication that connects the controller to actual elevator motion. If these wires touch it is possible for accidents to result.
In this video I will quickly show you how to look for hidden dangers and minimize the risk.

Thank you for your comment.

I once had a car begin to level in on me just as I was taking it off car top inspection the hatch doors were open but the gate was made..I hit the stop switch and went to the MR and found the normal wires were touching the slow limit in turn feeding the door lock..wow was that an eye opener..

Excellent Find. You may have saved someone's life down the road. Well done.

There's no excuse for the amount of exposed copper on some of the terminals in that unit. It's not hard to strip excess and then trim it so that the terminal gets a good bite on the copper with the insulation just barely butting up to the terminal. The opposite is those installers who stuff the insulation into the terminal and grip onto the plastic leaving the copper floating.

I agree with you 100%. All should follow the practice of terminal maintenance.

You are correct. The installer is trained but induce a little bit of company and lapse in judgement and the risk for accident has just rises seven fold.

Excellent Question.

Yes. The wires are in a stable non moving environment. The only thing that moves and possibly may become unstable is the human intervention. By reducing the amount of wire exposure at terminals we are protecting the passenger from mechanic error.

At 3:13 very good option cut off excess copper.

The local traffic light installer always makes sure his connections have the insulation right up to the terminal.

Ah that's interesting and perhaps differing standards between nations or whatnot, but my tutor recently gave us the mean lecture after performing class maintenance on a removed and non live otis controller. (yelling) "I don't want to see A N Y copper from A N Y wire sticking out the top of a terminal block!!" - Pretty sure he was about to have an cerebral or brain aneurysm over it, lol!

My thoughts are "the wires are in a stable, non moving environment" ..
