9、 Installation and Maintenance Guide

9.1 Installation precautions

The MicroNet digital control system must be installed in a metal enclosure or cabinet to meet EMC directive requirements. Please refer to section 15 of manual 26166V2 for installation location and specific cabinet construction requirements.

The system grounding requirements are strict, and the grounding leakage current exceeds 3.5 mA. Before supplying power to the MicroNet control device, it is necessary to verify that the PE terminal is connected. Fixed wiring installation is required, and the main power circuit should be blown correctly according to national standards. It is recommended to use European T-type fuses.

9.2 Electrostatic discharge protection

The electronic control device contains electrostatic sensitive components, and the following precautions should be taken to prevent damage:

Release body static electricity before handling control devices

Avoid using plastic, vinyl and foam around printed circuit boards

Do not touch the components or conductors on the printed circuit board with your hands or conductive devices

9.3 Fault diagnosis and troubleshooting

The system provides comprehensive diagnostic functions, which can monitor system status, view fault codes, and configure network settings through AppManager software. Each module is equipped with LED indicator lights to display module status and fault information, making it easy to quickly locate and solve problems.
