Ok, today, we're gon na go over how to properly install an ICM 493 single phase voltage monitor with surge protection. We're doing these on all of our Infinity systems that have inverter boards on this particular one. We have our service disconnect on the right-hand side, and then we have our ICM 493 here so first off we're gon na want to come out of the disconnect into our voltage, monitor serve protector here on the backside of this I'll. Show you how it's actually wired up so, on the left hand, side, we're monitoring, voltage and then once we know our voltage is in line, then our board is going to activate our contactor, which is then going to send voltage to our actual condensing your network again.
So our line voltage is going to be wired into the left hand, side and then our load, which is our condenser, is going to be wired into the right hand. Side on this board. You also have a three amp, low-voltage views all right, so that's pretty much. How it's wired up you have four different app cons.
Upper left upper right, lower left, lower right. This upper left one's a little bit tricky to get in, so you do have to remove these two screws to get easy access to that upper left-hand side, obviously make sure everything's perfectly level silicon the top portion, that's up against the wall. So then you close it up this particular one has a set screw right here, put that in and we'll go through the programming. Okay.
So for our setup, IC M 493. You just push the actual set up button. So first you're gon na push the setup. It's gon na ask you the line voltage.
So what is this appliance visit of 2a, 240 or whatever? It may be, this particular one's a 240 over under voltage percentage, so we are going with five percent under or over 240 volts will actually open the contacts. That's providing voltage to our load, so we want to go with 5 %. Then we're gon na have line voltage 240 over/under anti short-cycle delay. This comes at 30 seconds.
I bumped it up to two minutes reset mode, so you can change this from one trial or automatic. I went over the pros and cons with the customer and we chose to go with automatic on this one aloud. Mov fails five, this one. You can also change that as well.
We're gon na go with five and that's pretty much it as far as the setup goes. The last step is actually calibrating the ICM 493. How you're going to do this is push the up and down arrows until your line voltage starts to flash and with that RMS meter, you're, going to check your line voltage between l1 and l2 go up and down, as required. This one's already dialed in at 242.
Volts once you got it, dialed in you just push the setup button and you are good to go, and those are all done so remaining mov s5 and the actual voltage that we are receiving is 243 and that it will fluctuate this one's fluctuating between about 242 And 243.
These get hotter than 140F commonly for anyone else?
Should be set at 4 failed MOVs and have it Disconnect. This forces the customer to call for service to Diagnose. Upon discovery that 4 MOVs have failed, that would be a definite Sign of an Issue or perhaps just age. It would then allow for the 5th one to be Selected for continued operation to Retain Protection with the customer being notified of the issue and requirement to replace the controller due to Damage. How frequently this would happen is Unknwon of course but cheaper to replace the ICM493 than anything in the condensing unit. The Bad part is once that 5th MOV burns out…. Zero protection left with continued Operation. So moral of all of this…. Set it to 4. Leave 5 for restoring operation while ordering a replacement ICM493.

Why did you use two surge protectors?
I like the ICM’s four strikes and your out feature, redundant movs on the disconnect with their $7500 guarantee (wonder if anyone actual collects on surge suppressor warranties), but I wonder about both system’s grounding path and the electronics in the ICM box itself. It may be an academic argument, but I lean to protecting the whole house at the incoming panel since ground paths are better and there is a chance to prevent dangerous voltages and frequencies from finding their way back to the inverter from the comm wires. At some point opto isolation should be designed into the comm networks by the OEMs. Service area Barrhaven??
