Notes on voltage measurement
• In insulated, high-resistance or asymmetrically grounded forms of
power supply system and for single-phase systems
In these networks the current/voltage measuring module can be used only
with an upstream decoupling module on the system interface.
• Supply lines for voltage measurement
In the supply lines from the main circuit for voltage measurement of
SIMOCODE pro it may be necessary to provide additional line protection!
