6-Slot Chassis 474-BODY6R-R1

Excessive current draw
The 6-slot chassis with an internal power supply unit is not equipped with a fuse on its primary side.
 The protection against excessive current draw has to be provided by the electrical installation of the building.
Power supply voltage too low
With 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 chapter 6.3, page 66).
 With a current of more than 5 A, use an external power supply unit. In this case, redundancy is inapplicable.
