DANGER!
If you unplug the mains cable of the group 2 (B) power supply unit, the

group 1 (A) power supply unit, i.e. the central control module and the interface
cards in slots 1 - 6, will be functional.
If you unplug the mains cable of the group 1 (A) power supply unit, the

plied with operating voltage. (Refer to the illustration OpenCom 510: 1-12 frame
slots on page 27 to determine the location of the modules specified in parentheses

The LEDs of each module indicate whether the respective module is operational.
For further information on LED indicators, refer to Modules starting on page 59.
