You could decide not to search, just put a label on anyway. I looked at
the Preview of IEC 60947-1, but did not find anything. There is a 7th
edition in preparation.

Colleagues,
I have a client who has installed a COTS UPS in an industrial control
panel. The UPS is being used to keep the HMI alive in a power outage
or if the disconnecting device is switched off.
I have scoured the resources that I have, and I can find nothing that
requires a label on the outside of the panel to indicate that there is
a UPS inside. EN 60204-1:2018 does not address this. I have a copy of
EN IEC 62040-1, and it does not require a hazard warning label anywhere.
Any guidance you might offer is appreciated.
