Do not rely on the flow control SWG feature. My PLC code and I were not communicating well (forgot safety loop to ensure SWG was not left on alone) and the IC40 produced enough heat and pressure to push the seal out between the control panel and body of the SWG. I saw water dripping from it and grabbed it for an inspection to find a nice flow of current into my hand. Being the DIYer I am... I was able to repair it by drying it inside and out with a hair dryer and using black RTV between the surfaces. Has been in service for the last 2 years without problems. Might be some good info for saving 500 or so dollars.
