  The actual frequency range is 45.00 - 65.00 Hz 

3

  Absolute min/max value (lag or lead) 

4

  The exported energy registers are read as positive unsigned long (32-bit) integers 

5

  When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, 

they will be line-to-line voltages. 

6

  In the 4LN3, 4LL3, 3LN3, 3LL3 and 3DIR2 wiring modes, the harmonic voltages will represent line-to-neutral 

voltages; in the 3OP2 and 3OP3 wiring modes, they will comprise L12 and L23 line-to-line voltages.
