Hi, when installing a Multiplus 12/1600/70, does it need DC grounding from chassis to DC negative? It's a fixed UPS installation, so ground is already provided by grid AC in.
I can't find anywhere in the manual for the multiplus 1600va, where it is mentioned if and how DC grounding should be done. And the circled information for what i assume is the chassis ground lug, seems rather strange, I actually don't understand exactly what it means.
What is "chassis on input/output ground terminals" ?
I assume it means that chassis is connected to input/output ground and should have permanent "uninterruptable" ground connection? Which then in my case is already provided by fixed AC in.
Edit: And probably just a spelling mistake "on" Should be "or".
^ Appendix: B of Multiplus 1600va Manual
This example shows DC grounding.
