Switching off
Damage to the supply unit!
NOTICE
At regenerative supply units, at least 10 ms have to elapse between the
mains OFF request and the disconnection of the mains voltage, so that the
energy flow has been interrupted when the disconnection process starts.
You can make sure this order is observed by appropriate switch elements
(e.g., by a control cabinet main switch with leading auxiliary contact). For this
purpose, connect the auxiliary contact in series with mains OFF.

Time depends on device (mains contactor off delay); OFF re‐
lates to the hardware input
