Safety shutdown
The charge and control unit has three overload behaviors that can be selected.
Hiccup Mode
The output cannot be powered up within 5 seconds due to a short circuit or continuous over-
load.
3 startup attempts occur with a wait time of 20 seconds each. If no restart has occurred,
there will be a 5 minute break before the next start attempt.
Fuse Mode
The output cannot be powered up within 5 seconds due to a short circuit or continuous over-
load. The output remains switched off.
To end Fuse Mode, the “Reset Fuse Mode” button must be actuated. This button appears in
the UPS-Control Software in the “Overload Behavior” area as soon as Fuse Mode is enabled.
If the restart is unsuccessful, the next attempt can only take place after a wait time of 20
seconds.
Power Boost/Top Boost
(Only in combination with high-performance battery modules. Not compatible with BLOCK battery mod-
ules)
If a case of overload is detected, the charge and control unit enables increased loads to be
supplied temporarily using the Power Boost.
Power Boost : max. 65A for max. 10 sec.
Top Boost
: >65 A for max. 55 ms
The Power Boost in grid operation must be supported by the upstream power supply unit
.
Note:
Hiccup Mode is enabled in the factory settings. The UPS-Control Software is required in order
to activate Fuse Mode or Power Boost.
Fuse Mode or Power Boost can be selected in the UPS-Control Software under the “Parame-
ters” and “Overload Behavior” tabs.
