Polarity check for 1-phase current inputs IX1
Figure 2-16
The following applies for the (max. 4, dependent on device version on connections)
1-phase current inputs:
For the auxiliary measuring input X1
• Address 711 EARTH IX1 AT with the options Terminal Q7 or Terminal Q8,
• Address 712 IN-PRI CT IX1 = primary rated CT current,
• Address 713 IN-SEC CT IX1 = secondary rated CT current.
For the auxiliary measuring input X2
• Address 721 EARTH IX2 AT with the options Terminal N7 or Terminal N8,
• Address 722 IN-PRI CT IX2 = primary rated CT current,
• Address 723 IN-SEC CT IX2 = secondary rated CT current.
For the auxiliary measuring input X3
• Address 731 EARTH IX3 AT with the options Terminal R7 or Terminal R8
(not for high-sensitivity input),
• Address 732 IN-PRI CT IX3 = primary rated CT current,
• Address 733 IN-SEC CT IX3 = sec. rated CT current (not for high-sensitivity
input),
• Address 734 FACTOR CT IX3 = CT transform. ratio (only for high-sensitivity input).
For the auxiliary measuring input X4
• Address 741 EARTH IX4 AT with the options Terminal P7 or Terminal P8
(not for high-sensitivity input),
• Address 742 IN-PRI CT IX4 = primary rated CT current,
• Address 743 IN-SEC CT IX4 = sec. rated CT current (not for high-sensitivity
input),
• Address 744 FACTOR CT IX4 = CT transform. ratio (only for high-sensitivity input).
Note
For devices in panel surface mounted housing, terminal designations apply as per
table 2-4.
