DIRIS A-30<br />
Multifunction power metering & monitoring device - PMD<br />
Connections<br />
Balanced low-voltage network for DIRIS A-30<br />
Recommendation: When disconnecting the DIRIS, the secondary of each current transformer must be short-circuited. This operation can be carried out<br />
automatically by a SOCOMEC PTI: please consult us. In TNC mode, it is advisable to connect the DIRIS A-30 to earth using the functional earth module.<br />
