I've got the are sh-60 vmd hooked in I've, got it hooked up to the line voltage on the line side of the high voltage in tandem with the ground as well, and when we got our low side, what we're going to do is we're going to be Able to break the yellow wire going to the contactor on the outdoor unit. Okay, so today we're gon na be taking a look at the rector Co, our sh-60 v md with gas discharge tube technology. It is a surge protection device that is designed for single phase systems. Only this is what it looks like it's pretty heavy-duty inside you have the voltage monitoring device and the surge protector, the RS h-60, along with a separate.

This is just all encased together. It is UV resistant and weatherproof casing, and we got here. We got our crown and our two line line connections here and this is our low voltage. There's a low voltage relay inside these would break why your y one terminal.

So this is essentially going to turn the system off in the case of a brownouts under-voltage instance, or a surge so we're gon na protect the system. We will get an audible alarm as well and we can silence that once we realize what's going on, we have our LED indicators. We're gon na install this today. Look at our specs is compatible for 120 and 240 looks like our maximum continues.

Operating voltage is 304. 240, if this were going to be 240, when 90 is the minimum that is allowable and we'll probably take a look at that there. It is under voltage sensing for 190 volts and that's got a sense. It's gon na throw a fall for under voltage.

If it reads 190 or below, when you have a 240 volt circuit, got the installation instructions here. So we're going to make sure that, with proper installation, we're going to measure the voltage make sure that the phase, what we're reading we have either 120 or 240. And this is the setup we're gon na either hook up to the line and neutral with ground or win enough up to both legs at power and then ground, um and then, of course, we're gon na break defect. Get you there why, one by one? That's what we're doing we're breaking the contact or wider 24-volt, because there's a relay inside so you might be asking yourself what the heck is.

This gas discharge tube technology? Well, I'm about to tell you it's essentially a tube. That's filled with a plasma, gas or a rare gas, and it is going to be used to heat up and essentially they call the glow point of this rare gas and it is going to dissipate transient voltage to ground in the form of heat energy. Essentially, what this is going to do is it's going to help protect the metal oxide varistor which, as we all know, is a one-and-done we've ever had if anyone has ever had to change the motor module for an electronically commutated motor? If you look at the module itself, you'll see this little metal oxide varistor and that's what typically blows when you have to replace a module, because it's one and done essentially what we're trying to do here is protect the metal oxide varistor and prolong the life of This surge protector as this gas discharge tube sees the transient voltage surge. It's going to heat up, and it's going to dissipate that voltage to ground in the form of heat energy.

I've got the RS h-60 vmd hooked in I've, got it hooked up to the line voltage on the line side of the high voltage in tandem with the ground as well, and when we got our low side, what we're going to do is we're going to be Able to break the yellow wire I'm going to the contactor on the outdoor unit, and so what we basically are doing we're going to be breaking. Why so we just wire up to our Y here. Essentially, what this is doing is its allowing us to break power to the condenser in the case of a brownout or an over-voltage event, we've got everything wired up and when we turn this thing on, we will have a green light here and I'll show you guys What it looks like it's all hooked up, cleaned up all right. You can see the little green light flashing.

I've got the disconnect, turned off turn this bad boy on here, and I am on time-delay and just so you guys can see what it looks like all around completely done, that is it the RS h-60 VMD here we go. The green light is solid. We should be good to go again. This is a metal oxide, varistor x' that are going to effectively protect the equipment.

The metal oxide varistors are protected themselves by the gas discharge tube technology.
