SOLUTION
A power strip could be connected to
the UPS. Do not use it.
See also if there is any damage to the
utility wall receptacle or if the cord plug
is faulty. Replace them if needed.
If the problem persists, contact the
LEGRAND Technical Support Service.
Shut down immediately the UPS.
Disconnect the mains and contact the
LEGRAND Technical Support Service.
The function of autorestart is enabled
by default. When the mains is available,
the UPS restarts in normal mode to
