NOTICE
Too low power supply voltage
With Draco vario chassis 474-BODY6R-R1 a redundant power supply voltage is possible up to a current
of maximum 5 A (modules inclusive connected periphery). If the power supply voltage of the internal
power supply unit fails, the device's power supply voltage is secured via the 5 V external power supply
unit.
If there is no redundant power supply voltage and the current is above 5 A, the device is not supplied with
sufficient power supply voltage and fails.
 Note the maximum current draw of the chassis (see from chapter 12.3, page 59).
 With a current of more than 5 A, use an external power supply unit. In this case, redundancy is
inapplicable.
NOTICE
Excessive currents
The 6-slot Draco vario chassis with an internal power supply is not equipped with a fuse on its primary
side.
 The protection against excessive currents has to be provided by the electrical installation of the
building.
