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.
@@NotOurRemedy, is yours in morning, afternoon or all day sunlight? Mine is in morning sunlight and doesn't get hot. I guess I need to confirm that during the summer though...
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 didn't you install the ICM493 upstream of the disconnect, to put it closer to the power source where the surges should be greater? Also, you said it needed a good ground, but the electronics board isn't grounded. At least I couldn't find where the board was grounded. And if you installed it upstream of the disconnect, the equipment grounding conductor would be shorter and closer to the CB panel. Is there a good reason why you installed it just before the equipment?

there is a 40A and a 60A version ... my Compressor draws 45Amps. Which one do I need ? thanks !
Why did you use two surge protectors?
To make money from the customer!
The intro says why there are two on the system...
@@TershBlissett these things get to 140F while in sunlight with you guys. Mine does every afternoon.

@@TershBlissett afternoon. Late in the day.
On a 4 ton a PUMY.
Around 145F

Lack of info with dialog sucks.
Thanks for the vague overview
I like the presence of the other surge protector, with no mention.
Hi what if I am getting a reading of 252v. Can I adjust to higher then 240
You did not show how to actually attach wires inside - does panel have to come off ? Where do he wires enter the box ??
These get hotter than 140F commonly for anyone else?
Thank you. Good video
Can you do a video on the icm450
