NOTICE
The secondary voltage on terminal F (voltage) must not exceed AC 480 V (AC 347 V for UL conditions).
This could cause material damage.
•
Please make sure that the maximum permissible voltage on conductor - ground (PE) is not exceeded.
NOTE
For SICAM MMU (voltage measurement inputs galvanically isolated), the electrical connection PE-N is not
mandatory.
