Hi Guys this is my first time at this. So hope it works.
I have just put one of the above in my camper. It already has a VSR set up (voltage sentisive relay).
Do I disconnect the charge wire from the relay (VSR) and connect it to the in terminal on the 250s. Then add a new wire from the out terminal on the 250s to the to the charge terminal on the VSR. I have done this, but the power light doesn't come on. Maybe I have to connect the andersen plug to the vehicle?

I don't know anything about your voltage sensitive relay but you should bypass it if you intend using the D250S.

The input should come from the "charge" wire from the vehicle and connect directly to the input terminal on the D250S. the output from the D250S should go directly to the positive teminal on your battery bank, preferably via an inline fuse.

Trying to connect two pieces of electronic "management" devices together may introduce additional complications you just don't need.

The Ctek D250S has all the smarts in it to manage full control over the input from the vehicle alternator and the output to the battery bank in the camper.
