About the document

This manual discusses features of the Vigilohm IM10 and IM20 insulation monitoring devices (IMDs) and provides installation, commissioning, and configuration instructions.

This manual is intended for use by designers, panel builders, installers, system integrators, and maintenance technicians who are related with ungrounded electrical distribution systems featuring insulation monitoring devices (IMDs).

Throughout the manual, the term “IMD” and “device” refers to Vigilohm IM10 and IM20. All differences between the models, such as a feature specific to one model, are indicated with the appropriate model number or description.

This manual assumes you have an understanding of insulation monitoring and are familiar with the equipment and power system in which your device is installed.

Please contact your local Schneider Electric representative to learn what additional training opportunities are available for your devices.

Make sure you are using the most up-to-date version of your device’s firmware in order to access the latest features.

The most up-to-date documentation for your device is available for download from www.se.com.

The following table is profiled. Check the profiling before making any changes.

General Cybersecurity Information

In recent years, the growing number of networked machines and production plants has seen a corresponding increase in the potential for cyber threats, such as unauthorized access, data breaches, and operational disruptions. You must, therefore, consider all possible cybersecurity measures to help protect assets and systems against such threats.

To help keep your Schneider Electric products secure and protected, it is in your best interest to implement the cybersecurity best practices as described in the Cybersecurity Best Practices document.

Product related cybersecurity information

To help reduce the threat of cyber attacks on your (equipment/devices) systems, organizations, and networks from cyber attack threats requires multi-layered cyber risk mitigation measures, early detection of incidents, and appropriate response and recovery plans when incidents occur. For more information about cybersecurity, refer to the Cybersecurity Guidelines.

WARNING
Potential compromise of system availability, integrity, and confidentiality Change default passwords/passcodes/PIN codes to help prevent unauthorized access to device settings and information. Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks. Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection). Use cybersecurity best practices (for example: least privilege, separation of duties) to help prevent unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation. Failure to follow these instructions can result in death, serious injury, or equipment damage.
