INFOBEREICH
Die Angabe „MatNr/Version/Datum“ bzw. „1234560000/00/MM.YY“ ist als Textvariable deniert
und kann nur auf der „Rueckseite“ editiert werden. Die Textvariable erscheint in allen Doku-
menten dieses Buches, sobald eine Synchronisierung des gesamten Buches(!) durchgeführt
wird. ACHTUNG Die „Rueckseite” muss als Formatquelle(!) ausgewählt sein!
4.4.3.3 Jasic
• 7 Jasic programs can be executed simultaneously in the Energy Analyser 550.
• 128 kByte of memory is available for each program.
• Jasic programs are easily created with the graphic programming integrated into ecoExplorer go.
4.4.3.4 Relevant voltage
In three-phase systems, measurements can be carried out between the outer conductors and between the
outer conductors and the star point.
The relevant voltage indicates whether a measurement is to be made between the outer conductors (mesh
voltage) L-L or between the outer conductors and the star point (star voltage) L-N

4.4.3.5 Identity
• The name is used, among other things, to identify the device in the device list.
• Additional information can be saved under Description.
4.4.3.6 Transformers
Voltage measurement
• Three-phase, 4-conductor networks with earthed neutral line
• Rated voltages (L-N/PE) to a maximum of 417 V
• Rated voltages (L-N/PE) to a maximum of 277 V in accordance with UL
• Three-phase, 3-conductor networks, not earthed
• Rated voltages (L-L) to a maximum of 480 V
• Voltage transformers are necessary in networks with higher rated voltages
Voltage transformers
• The converter requirements for the main measurement and secondary measurement must be deter-
mined separately.
• Select the 400/400 V setting when measuring without a voltage converter.
Current measurement
• The Energy Analyser 550 can measure currents up to 5 A directly.
• Observe the installation guide when doing this.
• Transformers are used when measuring currents greater than 5 A.
