UPS MTD-XL UPS Device Description
MTD series 29
The plug-in connectors "UPS-Output" and "Mains-Input" are on mains po-
tential when connected.
However, there can still be a dangerously high voltage on the plug-in
connectors even while disconnected, due to device-internally loaded ca-
pacities.
As soon as mains input voltage is present, the loading unit is automatically
activated. I.e. the internal battery bank is already being charged, even though
the UPS has not been switched on.
