Using the NRG system without ‘REF’ terminal
connection
The NRG system can be utilised without connecting the ‘REF’ terminal however this will
constitute some limitations as
listed below:
1)
The following readings are not available: RMS Voltage, Real Power and Apparent Power
2)
The ‘TEACH’ operation can
not be executed
3)
Voltage out of range and Load deviation alarms are not available

The mains loss alarm cannot be discriminated from a load loss. Therefore, a mains loss alarm will indicate
either a mains loss or a load loss.
