INFORMATION
Current transformer ratios can be configured conve-
niently via the device menu.
For information on programming the current trans-
former ratios, refer to the chapter „10.2.2 Configur-
ing the current transformer ratios“ on page 48.
WARNING
Risk of injury or damage and fire hazard to the
device due to improper connection!
Disregard of the conditions for the connections, e.g.
connecting the voltage lines to the current mea-
surement inputs, may damage the device or cause
serious injury or death. Connecting the voltage lines
to the current measurement inputs also poses a fire
hazard!
Therefore, please abide by the following before
start-up:
·
Check the condition of the connections, in-
cluding the cabling, especially the connection
of the voltage and current measurement.
