1.4 Overload Protection
Load current is monitored by the IUPS. In case of an overload during battery mode the
IUPS switches off. In case of an overload during mains mode a permanent sound is gene-
rated, which will stop when the overload is eliminated.
1.5 Overtemperature Protection
When an overtemperature is detected by the internal temperature control, this is indica-
ted by the red LED and an acoustic alarm sound.
1.6 Replacement of front panel
The standard front panel can easily be exchanged. To do so, turn a coin carefully in the
recess at the side. A black front panel is part of the delivery.
