Irrespective of the status of the LED "DC LINK"
Table 10- 5 Meaning of the LED "POWER OK" on the Control Interface Module
POWER OK Green
DC link voltage < 100 V and voltage at -X9:1/2 less than 12 V.
The component is ready for operation.
Flashing
There is a fault. If the LED continues to flash after you have performed
a POWER ON, please contact your Siemens service center.
Danger to life when live parts of the DC link are touched
Irrespective of the state of the LED "DC LINK", hazardous DC link voltages can always be
present. This means that if live parts are touched, this can result in death or serious injury.
• Observe the warning information on the component.
