IEC starter How to Wire!!

today I'm gonna show you how to wire an IEC motor starter hi my name is Craig Michoud and I am the electro instructor today we're going to talk about IEC motor starters now motor starters you know we come in we have two different types we have a NEMA and we have IEC those are the two most common that we have I'll show you how to wire a NEMA motor starter in another video today we're gonna just focus on the IEC now why do we use the IEC well to be quite honest with you you can see that the IEC is much more compact you know a NEMA is much much more bigger and if you google other videos you know or look up on YouTube other videos you'll see that the motor starters are quite big these here do pretty much the same thing and we're gonna we're gonna go over these today so what do I need to know well what I need to know is how to wire we're gonna go over the different components now looking at the IEC motor starter okay on the top here is going to be what we call our line and our bottom here is what was going to be called our load so the power coming in the three-phase power coming into our motor starter will come in on the top three legs okay in the front here don't worry about the front yet and the bottom here will be the load this will be going out to our motor we won't be hooking up this today to a motor we'll do that in another video what we're trying to figure out is how do we wire the motor starter well one of the things that we have to remember just like everything else is and motor starter has a coil in it and that coil pulls in when we energize when when we give a power so when we energize it it pulls it in now the nice thing with the IEC is it has built in normally open and normally closed contacts now these normally open and normally closed contacts there's only one normally open and one normally closed so we only have two sets of contacts that we're dealing with one of the advantages that we have is we can hook up lights to this but we also are going to have what we call a one and a - which is kind of like our - in our seven and also our - in our 10 when we're dealing with an a pin or an eleven pin relay so you know for this type we're gonna be dealing with a 1 and a 2 now there's other control relays out there that also use a 1 and a 2 they're also an IEC brand basically what you're gonna end up doing is you know eventually I'll put out another video with an IEC control relay if you haven't seen my control relay my square d type click the link above and and watch that one that'll give you a little bit of an idea on how the coil works but what we're gonna focus on today is how we hook this up okay so let's get back to this when we look at the front you can see we have the front three screws and on these screws here and here is our a one and our a two meaning our hot and our neutral can go here and that is basically what's going to be pulling in our power this is a hundred and twenty volt coil so we'll put 120 volts here if there was 24 volts this would be a 24 volt coil again make sure you remember what the control voltage is so that you install the right type of device because if you put 120 volts - a 24 volt coil it's not going to be good look at this here the middle pair again is like our switch that is going to be our normally closed and our out brand here which is completely opposite of our a 1 and a 2 coil that's going to be our normally open what we're gonna do today is we're gonna hook up the coil okay we're gonna hook up normally open and normally closed which is going to be our green light in our red light we're gonna hook up this control relay and we're gonna pull it in and we're gonna turn our lights on and off so that you can see how it works it's important you guys understand that these instructional videos are meant for students who have never wired anything okay so I try to keep this very basic and very simple but even if you've been out in the field for a long time and you haven't done this in school or you haven't done it for a long time these video our I'm trying to give you the informative brand of this so basically what we did in our other video we wired a start/stop station which the link is up here go and watch that start/stop if you don't know how to wire that part of it because today what we're gonna do is I'm just gonna hook up the motor motor starter so that I can show you where the connection points are on the reel on the motor starter okay so what we're gonna do is we're gonna take this IEC now the nice thing with the IEC is we're gonna use this bar here which is called din rail din rail is great because we can add anything we can add eight pin eleven Penn Relays we can add IEC control relays we can add motor starters we can add forward and reversing motor starters which I'll be showing another another video so basically what do we do on the back here you can see there's a little bit of a groove here okay and basically all we're gonna do is we're gonna take it and we're gonna pull down on the din rail slide it in push it up and the little spring in here will hold it in place okay so what we're gonna do now is we're gonna hook up our control relay okay and what we're going to do is that control relay is going to be a 1 and a 2 we're gonna start with the neutral first I like to use a two as my neutral it just kind of helps me kind of comprehend what I'm doing now let's hook up a two now what we're going to do is we're going to hook up a one which is our power coming off of a start button now just like everything else - I've got to get my power to my normally-open a my normally-closed so what I'm going to do is I'm going to take that okay so we have we have our power coming in to our normally open which is then jumped over to our normally closed here which is then feeding the top portion now I'm gonna operate my lights so that you can see that it's operating and it's not operating or it's opening and closing the bottom section here my normally open I had connected my green wire my green light to it down here I connected my red light to it okay this little wire here is my holding circuit which is jumped from here back up to a 1 because remember I need to have that power to hold that relay in okay my neutral is connected my power or my initiation is coming from one side of my green button again if you haven't already watched my start/stop video on how to wire the start/stop please go watch that video it should be in a card above let's see if it works okay so now I've got the power on you can see that my red light is on okay telling me that my power is there meaning my motor starter is ready to go I press my green button you can see my red light went off and my green light is now on meaning that my motor starter now was pulled in so if I had a motor connected to this thing the motor would be spinning I press stop green light goes off red light goes on letting me know that now I'm ready to go you just have to remember with a motor starter all you have to remember is I gotta feed the coil I got to know what my control voltages this one here has auxilary contacts on it so you're using the auxilary contacts to control lights or different devices maybe a control relay so your auxilary contacts can be used for a multitude of different things again your motor starter you just have to make sure you got the right motor starter for the right ocation for the most part my suggestion is you're gonna find it on a drawing so don't worry too much about that at the same time motor starters are relatively easy to install I hope you liked my video if you like my video do me a favor give me a thumbs up again it's always good to hear from you so if you want leave me a comment down below and if you haven't already subscribed to my channel please subscribe to my channel you know we're on the brink of hitting two thousand subscribers this channel is growing very very fast I really appreciate everyone of you guys watching my videos is I am very appreciative that you guys watch my videos as always have a great day and be safe
