6.2 EARTH LEAKAGE MONITORING (OPS-02)
This option is used to detect a possible leakage current flowing from the DC source to the ground. It
is especially preferred in industrial applications and power plants.
Figure 6.3 Earth leakage condition
When a current from any of the positive or negative poles of the input of the inverter flows to the
ground, an unbalance occours in the measurement of the DC bus voltage respect to ground. This
unbalance condition is detected by the Earth Leakage Monitoring Board. DC inputs to the Earth
Leakage Monitoring Board are fuse protected.
