2.) Bypass mode:
Bypass mode protects the internal electronics by preventing
them sustaining irreparable damage as a result of impermissi-
bly high current or overtemperature.
In normal mode, the UPS switches to this mode automatically
in the event of an inverter fault, overtemperature, etc. In by-
pass mode, the load is supplied with power directly by the
input voltage.
In bypass mode, no battery back-up protection is afforded!
The battery continues to be charged. In this operating state,
the
“LINE” and “BYPASS” LEDs light up.
3.) Battery mode:
If, in normal mode, the input voltage strays outside the defined
voltage and / or frequency tolerances, or in the event of an
absolute power failure, the UPS will switch to battery mode
automatically and without interruption of supply. The rectifier
and charger will be rendered inactive.
In battery mode, the “BATTERY” and “INVERTER” LEDs light
up.
9.2 Switching on
There are two ways of switching on the UPS:
9.2.1 Normal start
(input voltage present)
Connect the UPS to a building wiring socket outlet (with
earthing contact) and press the ON-button until you hear an
audible signal (approx. 1–2 seconds). The UPS will start a
self-test at this point and will switch to
normal mode once it
has completed this test successfully.
