Observe applicable standards and regulations
During installation, connection and use of the I/O module, observe all relevant
current regional, national and international standards, installation requirements
and accident prevention regulations.
No hazardous voltage is produced on the current measurement inputs when the
I/O module is used with appropriate current transformers according to the
specifications. Secondary voltage is a low voltage level. However, the following
fault cases can result in high voltage levels on the secondary side of the current
transformers:
• Open current path for one or more current transformer
• Disconnected PEN conductor at the voltage measuring end of the
I/O module
• General insulation fault
