6.3. Connecting to the electrical network and circuits
The insulation monitoring system ISOM Digiware is suitable for single-phase, two-phase, three-phase and continuous
networks.
The insulation monitoring module ISOM Digiware L-60 ensures the insulation of a complete powered IT system is
monitored. It automatically detects a DIRIS Digiware U module to ensure PMD measuring.
Each ISOM Digiware F-60 fault-locating module can monitor multiple live circuits at the same time. This approach
allows great flexibility in terms of where it is fitted in the installation.
The circuits are monitored (faults located on AC and DC and load currents measured on AC only) using several types
of current sensor (closed, open, flexible) selected depending on the new, existing or high-current installations.
The link between each ISOM Digiware F-60 fault-locating module and its associated sensors is made using specific
cables. With this connection you can quickly and easy install the units without any risk of cabling error and in
complete safety. The connected sensors are automatically detected.
In addition, ISOM Digiware can identify the majority of load types to be measured: single-phase, three-phase with or
without neutral using 1, 2, 3 or 4 sensors for balanced or unbalanced loads.
The overall accuracy of the ISOM Di sensors measurement chain is guaranteed. To guarantee this accuracy,
SOCOMEC current sensor connection cables or equivalent must be used.
