The symbol I mentioned in my original question looks similar to the 5173
but it is not identical (see below).

My question is: can this symbol be used for marking of a terminal to which
return (0V) wires of redundant DC POWER sources are connected? If not, what
symbol would you use? 0V?

Hello group,
What is the meaning of a symbol that looks like an upside down letter
"T"? Can this symbol be used for marking of a terminal to which return
wires
(0V) of redundant DC power sources are connected? Note: The subject
terminal is not grounded.
Thanks for your help.
