Meta System HF TOP LINE 910 Bedienungsanleitung Seite 12

Never disconnect the 230V power supply plug while the UPS is in operation, as this eliminates
earth protection of both the UPS and the connected loads.
As the leakage currents toward earth of all the loads are summed by the protection conductor
(earth wire) of the UPS, check that the sum of these current values does not exceed 2.7 mA
for safety reasons according to the EN 50091-1 regulation.
The UPS is equipped with a circuit to protect against any connection error, which is
signalled by the red protection LED and the continuous beep of the incorporated buzzer.
Should this occur when the UPS is switched on, disconnect the power plug
immediately.
If you notice a brief flash of the red overload LED every 3 seconds after all the connected
loads have been switched on, the load connected to the UPS is at the maximum limit allowed.
