Power supply failure • Totalizers stop at the last value measured.
• Depending on the device version, the configuration is retained in the device memory or
in the pluggable data memory (HistoROM DAT).
• Error messages (incl. total operated hours) are stored.
Overcurrent protection
element
The device must be operated with a dedicated circuit breaker, as it does not have an
ON/OFF switch of its own.
• The circuit breaker must be easy to reach and labeled accordingly.
• Permitted nominal current of the circuit breaker: 2 A up to maximum 10 A.
