Do these converters have common negative, or are the positive sides tied together?

I don't have a schematic but the negative terminals measure zero ohms between them. The positive terminals show a high resistance. So I would say it is common negative. The two mounting pads appear to be isolated from the rest of the circuit.

They have a common negative or ground. The positive side is switched through the regulator

Usually the center connector is Positive. Use your DMM to determine the polarity.

I am not sure as i have covered the connection up so that the terminals could not be accidentally crossed by something. I installed the largest cables you could find on Amazon and they bolted right up. I would say they are on the large side for a converter. It does the job on a stand alone deep cycle battery very well.

Yes, there are two positive wires. One goes directly to the fuse box for constant power (always energized when the float is raised) and the other can be hooked to a switch for manual operation. That is how I installed mine.

No it is not. Also do not try to use it on a converter, as I already broke one

This adapter is Alternating Current. There should not be a positive or negative terminal defined. Double check the label to make sure it lists AC 24 or say AC/AC on it.

You have to put them in parallel to maintain 12 volts in the system.all positive together all negative together.assuming you're inverter and charge controller is 12 volts

I do not know. The Cross website only shows two converters and should list what they work with.

Make sure the polarity is correct. The negative pin -- Is marked on backside.

the common is for your input voltage you want to use for the output(no/nc). Your neutral or negative would go to the device you are controlling. The output(no/nc) would then go to the hot or positive of the device you are controlling.

From the Cross website, they only have two converters. This one, which works for most (as I recall) and the other one which works for a few.

I already had a converter but I don't know if one was supposed to be included. I do not remember getting one.

Yes. The positive pole is on one end and the negative pole on the other. It is very easy to hook up and operates great.

I had the same problem (question). The label on the hour meter says that the connections are polarity sensitive but when using to monitor AC usage, there is no polarity. I communicated with the vendors customer rep., and was told that they had engineered the counter to be able to be used in a AC or DC application, but to save money with parts that had already been labeled, they continued to ship the new design with the old labels. They told me to use the meter (counter) without regard to the plus and minus lables. I tried it and it works.

I agree with T. Thomas, sounds like reversed polarity - it's easy to do as the documentation is not very clear on the wiring.

The polarity of the T connectors is standard -- the top bar of the T is positive and the post is negative. The labels on the diagram in the instructions are misleading since they are opposite to the orientation of the T sockets.

Not sure off top of my head. Normally I use a voltmeter to check these things. Properly designed circuits will have a blocking diode to prevent polarity reversal issues. Those that don't, may have smoke issues!
