NOTICE
Too low power supply
With Draco vario chassis 474-BODY6R-R1 a redundant power supply is possible up to a current of
maximum 5 A (extenders inclusive connected periphery). If the power supply of the internal power supply
unit fails, the device's power supply is secured via the 5 V external power supply unit.
If there is no redundant power supply and the current is above 5 A, the device is not supplied with
sufficient power and fails.
Note the maximum power consumption of the chassis (see from chapter 9.3, page 45).
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.
