2.3.1 Standby Switch
The standby toggle switch connects (ready state) or disconnects (standby state) the
internal modules of the frequency converter from the power supply.
A green light-emitting diode (LED) next to the switch indicates that the instrument is in
ready state. An orange LED further to the right indicates that the instrument is in
standby state. These LEDs are only lit when the converter is properly connected to the
power supply and the fuse of the instrument is intact.
