Local isolator

MrJack96
Hi guys I’ve come across a local isolator that has been linked out for a motor but still can be isolated upstream. Trying to get my head around emergency switching and if a local isolator is the means of it. I always thought it was just e-stops where used for emergency switching. Guess my question is is it a big no no that’s this has been done? The isolator is getting replaced when the parts are in. 


cheers guys

    MrJack96:

    So what is the key differences between emergency switching and emergency stoping?  


    537.3.3


    Devices for Emergency Switching Off


    "Emergency switching off is an emergency operation intended to switch off the supply of electrical energy to all or part of an installation where the risk of electric shock or another risk of electrical origin is involved. "


    Emergency Stopping is defined as "emergency switching designed to stop an operation." This would involve stopping a working machine or mechanical system such as a conveyor belt in a factory.
