MI00551-8-EN INSTALLATION MANUAL 6/8
ELECTRICAL CONNECTIONS
The installation of this appliance must only be carried out by qualified personnel.
Check that the device plate data (measurement voltage, auxiliary power supply voltage, measurement current, frequency)
match the actual data of the network to which the instrument is connected. In the wiring, strictly observe the insertion
diagram; inaccuracy in the connections inevitably causes false measurements or damage to the instrument.
Once the instrument is connected, complete the installation with the device configuration.
Grounding of the TA sensors is possible with negative cable connection.
Current measurement is only possible using current transformers.
It is advisable to insert a delayed 1 A fuse as shown in the diagrams below.
