1. General
1.1 Contents of Delivery and Storage
Please check immediately upon reception whether the delivery is damaged in any
way, for which packing damage may be an indication. The contents of delivery are:
1 UPS unit IUPS-401-B1
1 Slot bracket with 5-pole control cable
1 Mains cable
1 User’s Manual
1 Black front panel
1 CD with software RUPS 2000OEM
For storing the IUPS for some time it is recommendable to charge the batteries of the
IUPS-401-B1 before for at least 8 hours. During storage the batteries must be charged
every 6 months. The storage location should be cool and dry.

upply IUPS-401-B1 is an integrated UPS unit
(400 VA / 240 W) and designed for mounting into a 5 1/4“ drive slot of a computer.
Interfering and dangerous overvoltage, transients and voltage surges are effectively
filtered during mains mode by means of internal filters. Destruction of important data
and hardware damage is thus prevented, which extends the service life of the system.
In case of undervoltage or overvoltage of mains power or mains power failure the
IUPS-401-B1 takes on the supply of the connected system. In back-up-mode the PWM
inverter pro-vides the required voltage.
1.3 Automatic ON / OFF Function
As soon as the IUPS is connected to mains supply the internal load sensor automa-
tically checks whether a load (computer) is connected at the output. When no load
and no mains input voltage are detected, the IUPS switches off automatically within
app. 20 seconds. As soon as the correct mains voltage returns the IUPS automatically
switches on again. The downstream load is supplied with mains voltage. By pressing
the button (>2 sec) the load at the output can be switched on or off.
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 generated, which will stop when the overload is eliminated.
1.5 Overtemperature Protection
When an overtemperature is detected by the internal temperature control, this is
indicated 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.
