## Questions & Answers

**Q: Does it come with instructions to install?**
A: No.  Very easy to install.  The Black and White wire pair.......black usually goes on the air conditioner fuse (TYPICALLY) and the white goes to the white neutral terminal connector.  The blue wire goes to the 12 volt fuse panel.  Just put it to the same location as the one was from your old inverter.  The other white wire goes to the chassis ground terminal connector.  You may see some other white wires and/or green wires on this terminal connector.  You know you have it wired correctly if you turn off or disconnect your batteries in your camper and the 12 volt lights work.  Hope this helps.

**Q: I Don't see the fan? Does the new ones come with a new one?**
A: Yes, there is an internal fan that works on a thermostat to cool the unit.

**Q: Does it have multi charge levels and desulfation? My old parallax Model 555 over charged batteries.**
A: Working properly the 5355R will not fry your batteries.  I believe it is a 3-stage converter.  Although my unit failed after a few uses.  I called Parallax and they do not back their warranty for Amazon purchases.  They claim that they do not provide units for sale by Amazon and anything purchased from Amazon is from a questionable source.  It turns out these units are actually refurbished by a 3rd party in Mexico as indicated by a label on the unit.  I called Amazon with my investigation results and they provided a full refund for the unit.  They indicated they would further investigate the false advertising issue. I have no word back from them.   I then purchased a 4 stage converter replacement for the 5355R from another supplier and am very pleased with the performance.  This type of converter provides improved performance and will definitely not overcharge your batteries.

**Q: is there a warranty on this?**
A: Parallax does not honor the warranty if purchased on Amazon.  My "new" unit failed after a few uses.  It actually has a refurbished in Mexico label attached to the unit.

*by C***R on Reviewed in the United States on June 1, 2018*

Got it in last night. My trailer is a 50amp that used a parrallex 500 series mode 555.  I pulled out the old one which has 5 wires 1 small black and 1 small white which hook up to the breaker.  Then 2 large red wires for positive and 1 large white wire for ground.  This new one i brought came with 6 wires the difference was that instead of red wires they are blue and it comes with 2 large white ground wires. So be aware of the change.  Even though this also a 500 series charger/converter it is much smaller then the origional and didnt fit the casing screw holes so i had to modify by making new screw holes for the mounting plates. Made sure power was off to the whole trailer and unhooked the battery.  Pulled out the old one put in the new one. Turned on the power and i believe it works. My batteries are holding a charge now. Only concern is that the converter/charger fan is on all the time now..i know i is working..i just hope it isnt boiling my batteries.  I will update if any issues arise in the next couple of months so far so good. It is nice to not have to hook up my battery to a battery charger in my garage.  By the way i am hooked up to shore power all the time, and have been for the last 2 and a half years.Update: 1 year and half later: still works great. The fan continues to run full time which is ok it isn't loud enough to be noticeable for us. Keeps my batteries charged and never had any issues whatsoever. Just make sure you take your time to install it correctly.
