Hi
On multiplus 2 pictures of units, on some of the schematic's on the front panel the AC input line shows 2 relays / contractors in series, where as some pictures of units only show 1.
Why is this.?
Thanks

Multiplus 2 ac input
From some point during time, the safety rules in some countries demand 2 series relays for AC disconnect.
So older units have 1 relay, newer ones 2 relays.
