If KLEA is used together with current transformers, please pay attention to the following warning.
Threshold values for proper operation of current transformers diff er according to the
type and size of the transformers being used.
Before applying the points mentioned in the following warning, please check that
the measured current value is larger than the current threshold value of the current
transformer (Refer to manual or datasheet of the current transformer).
For both of the warnings below, there must be a current in the system which is higher
than the threshold value of the current transformer (if any).
If KLEA is placed in a panel which consumes power;
The signs on Measure/Instantaneous/Active Power screen, should be positive, as the
phases consume power.
If there is a negative sign, turn off the device, cut off the panel power and then cross
connect K and L ends of the current inputs belonging to the related phase(s). After that,
check that all values are positive on Measure => Instantaneous => Active Power screen.
If KLEA is placed in a panel which generates power;
The signs on Measure/Instantaneous/Active Power screen, should be negative, as the
phases generate power.
If there is a positive sign, turn off the device, cut off the panel power and then cross
connect K and L ends of the current inputs belonging to the related phase(s). After that,
check that all values are negative on Measure => Instantaneous => Active Power screen.
