Useable BaseUnits
You can use the following BaseUnits:
● Type BU type U0 dark-colored
● Type BU type U0 light-colored
A potential group opened with a light-colored BU type U0 must contain no dark-colored
BaseUnit of BU type A0 or A1.
Connection types
The AI Energy Meter HF supports the following connection types:
● 3P4W1, 3 phases, 4 conductors, balanced load
● 3P4W, 3 phases, 4 conductors
● 2P3W, 2 phases, 3 conductors
● 1P2W, 1 phase, 2 conductors
● 3 x 1P2W, 3 x 1 phase, 2 conductors
● 3P3W, 3 phases, 3 conductors
● 3P3W1, 3 phases, 3 conductors, balanced load
● 3P4WI, 3 phases, 4 conductors (only for current measurement)
The input circuit of the module must correspond to one of the listed connection types. Select
the appropriate connection type for the intended use.
You will find examples of connections in the section Connection examples (Page 23).
