11. Configuration
11. 1 Measurement
The device has 4 measurement channels for voltage
measurement (V1 - V4 against Vref) and 4 measurement
channels for current measurement (I1 to I4).
Measured voltage and measured current
for the measurement channels 1-4 must
derive from the same network.
11. 1. 1 Baseline measurement
(measurement channels 1-3)
The baseline measurement uses measurement
channels 1-3. Use measurement channels 1-3
for measurement in three-phase systems.
You can choose one of 14 measurement
switches for the baseline measurement. The
relevant connection illustrations are provided
in section “6. 6 Connection variants”.
You can use parameter address “110” to set
the selected measurement switch.
Selectable measurement switches:
• 0 = 4w3m (factory default setting)
• 1 = 4w2m
• 2 = 4w2u
• 3 = 4w2i
• 4 = 3w3m
• 5 = 3w2m
• 6 = 3w2u
• 7 = 3w2i
• 8 = 2w2m
• 9 = 2w1m
• 10 = 4w3m_hv
• 11 = 4w2u_hv
• 12 = 3w2u_hv
• 13 = 3w2m_hv

measurement, address 110 with a content of 0.
11. 1. 2 Supporting measurement
(measurement channel 4)
The supporting measurement only uses
measurement channel 4.
Use measurement channel 4 when measuring
in single-phase systems or in three-phase
systems with symmetrical loads.
The frequency setting and the setting
for the relevant voltage are pulled automatically
from the baseline measurement settings.
You can choose one of 3 measurement
switches for the supporting measurement.
The relevant connection illustrations are
provided on page 23.
You can use parameter address “111” to set
the selected measurement switch.
