Re: Generator high voltage problem Reply #25 – January 25, 2013, 12:20:19 pm I don't know about consensus, but I was talking to the progressive systems representative at the booth at the Quartzsite show, and I asked him that very question. He said that the only place they will install them is on the input side of the equation (where shore power enters the coach). He stated that in 14 years of doing this he had only heard of one problem where the generator caused issues. I was all set to put it after the transfer switch, but now I am thinking I will just put it on the shore power side. That would definitely be the easiest installation, but I'm still open to change my mind...DonQuote from: John Haygarth – January 25, 2013, 10:29:51 amSO, has there been any more thought as to best place to hook up EMS since the last posting. Before, in the middle or after Transfer switches?? It will be one of my next fixes so nice to get it right!John H Quote Selected

Don That's where I have mine installed and it was a much easier installation than it would have been on the genset side (at least on our coach). Steve & Michelle gave me some good guidence on the placement although I believe theirs is on the genset side. I have a feeling that replacing the transfer switch might be an expensive proposition so that's the way we went. If I remember correctly the installation instructions do show options for both.

Re: Generator high voltage problem Reply #27 – January 25, 2013, 04:04:20 pm Don,As you said, installing the EMS before the transfer switch would be the easiest approach; however inasmuch as I have already had an occasional generator glitch, I wanted my appliances to be protected from high/low voltage fluctuations while on either generator or shore power. Therefore, I installed my Progressive in between the transfer switch and the main breaker box, in fact just adjacent to the breaker box at the foot of the bed. It made it easy to place the remote LED. If I can find pics I took during installation, I'll post one. Quote Selected

Ours is installed after the transfer switch, to protect against both shore and genset issues. Since we had a generator issue in 2010 we wanted to protect against anomalies there.Michelle Quote Selected
Re: Generator high voltage problem Reply #29 – January 25, 2013, 06:16:35 pm I also asked the Quartzsite booth guy and he told me the same thing. Except he is out of touch on his reasoning because here in Quartzsite Lemon Rally with 50+ coaches, there are two Foretravels with PowerTech generators putting out 166 volts and 144 volts. I would say he is not informed.That said it looks like if we want to protect against high generator voltage the EMS must be installed between generator & transfer switch or between transfer switch & main breaker panel.And if want to protect against shore power problems hurting our coach electronics, we need to install the EMS between shore power cable & transfer switch or between transfer switch & main breaker panel.And if we want to protect against shore power problems that can back-feed to generator and damage generator, EMS must be installed between shore power cable & transfer switch.It seems to me that it is all personal choice as no one solution will cover all three issues, so there is no one correct answer. I am considering in spending another $330 to install a second EMS between shore & transfer switch as it seems like good insurance. We currently have our EMS between transfer switch and main breaker and it just saved our coach from problems from our generator's 166 volts, which is my first choice location based upon personal experience. We do check volts & polarity before plugging in so we will catch a pedestal with a consistent problem. Quote Selected
Re: Generator high voltage problem Reply #30 – January 25, 2013, 07:51:05 pm so as I never use the genset I can go between the transfer and breakers OR put it in front after shore power. I think I will do it before circuit breakers.John H Quote Selected
Re: Generator high voltage problem Reply #31 – January 25, 2013, 07:53:29 pm Just bought a second EMS to install after the transfer switch. Don't want to be somewhere and have the transfer switch fried, and also don't want to have all the inboard equipment fried by a generator glitch, so the two EMS solution seems right for us. I will move the inside display to the one after the transfer switch and put the display for the shore-side one at the foot of the bed, or maybe eventually in the utility bay. Can't wait to start wrestling with that 6Ga wire again... Quote Selected

Re: Generator high voltage problem Reply #34 – January 26, 2013, 05:38:33 am Is there a spec sheet for this device ? Would be interesting to know at what voltage it accepts and what voltage it rejects in addition what is the time delay to act.Prefer 108-132 VAC and instant disconnect, not 2 seconds later, same on frequency 57-63 Htz range.Dave M Quote Selected

Re: Generator high voltage problem Reply #41 – January 27, 2013, 11:25:40 pm Finished installing the inboard Progressive EMS (after the transfer switch).
