12.4 Connection of Auxiliary CT Terminals
DANGER
Failure to use 0.33V CTs will damage the CT
Strip and can also result in serious injury or
death as unburdened / current output CTs can
result in lethal voltages.
DANGER
Si vous n’utilisez pas de TC de 0.33 V, vous ris-
quez d’endommager la barrette de tomodensi-
tométrie et de provoquer des blessures graves,
voire mortelles, du fait que les TC à sortie de
courant / courant peuvent entraîner des ten-
sions mortelles.
Each CT strip is equipped with three auxiliary CT
terminals designed to support CTs for panel main
input monitoring. The inputs are designed exclu-
sively for 0.33 V output CTs. Note that the assign-
ment of channels to the CT Strip Auxillary terminal
block will vary with the specific register map being
used.
Always connect phase currents from the input
source to the auxiliary terminals on a single CT
strip designated with auxiliary CT terminal block
numbered 1. Failure to do so will result in incorrect
current and power calculations for the main input
circuit. Observe the polarity of the CT wires as
noted in figure 20.
