Description of the front panel (fig. 1)

Generally, the keys located at the front panel fall into two
different basic groups.
•

Operating keys

•

Function keys for menu guidance

The LED’s located in the front panel’s upper area serve for
signalling the following system statuses:

•

Operating status display

•

Overcurrent blocking

•

Undervoltage blocking

•

Overvoltage monitoring

•

Parallel operation

•

NORMSET
