6.2. connecting to the electrical network and loads
The DIRIS Digiware U-xx modules can be used on single-phase, two-phase or three-phase electrical networks.
Each DIRIS Digiware S-xx current sensing module can use its three current inputs to simultaneously measure
several loads, for example three single-phase loads.
In addition, within one DIRIS Digiware system, different load types may be measured. For example, several Digiware
S-xx modules may be configured as single-phase loads while others may be configured to measure three-phase
loads.
This approach allows great flexibility within the electrical installation which may contain several different load types.
6 .2 .1 . Configurable loads based on the network type
The following table summarises the loads which can be configured based on the installation's network type
