1
During the power consumption measurement, the relay is powered at rated auxiliary energizing
voltage and the energizing quantities are energized without any binary output being active
2
During the power consumption measurement, the relay is powered at rated auxiliary energizing
voltage and the energizing quantities are energized to activate at least half of the binary outputs
