Switching Off The Ups - AEG Protect B. 750 PRO Operating Instructions Manual

UPS device at any time. If the device does become overloaded,
however, "OVERLOAD" appears in the display and an audible tone
is emitted. The connected electrical loads continue to be supplied
with power for a specific period of time which depends on the
severity of the overload, but the connected load must be reduced
immediately.
Not heeding the "device overload" condition can lead to a
complete failure of all UPS functions!
Also avoid brief device overloads, e.g. as can occur when
connecting a laser printer or a laser fax machine. Do not connect
household appliances or machine tools to the UPS.
In general, overloads should not occur in battery mode if they do
not occur in normal mode.

Switching OFF the UPS

If the UPS is in operation, it can be switched off by pressing and
holding the "OFF" button for approx. 3 seconds. The power
supply is interrupted immediately, i.e. all electrical loads
connected to the UPS are switched off.
Never connect or switch on additional electrical
loads to the UPS if a mains failure is in effect. The
UPS is operating on emergency power!
If the red "FAULT" LED lights up and an audible
tone is emitted, a switching-off malfunction is in
effect. Follow the instructions in Chapter 9, starting
on Page 43.
