5. Installation Precautions
The installation shall comply with the general installation requirements for Relion series expansion modules (refer to the official manual of products in the same series):
- Installation Position: Insert the module directly into the internal expansion slot of the protection relay, and ensure all power is cut off before operation.
- Connection Method: Communicate with the host device through the internal backplane bus without external wiring required.
- Fixing Method: Adopt guide rail or slot-type fixing to ensure the module is fully and securely inserted.
- Grounding Requirements: Correctly connect the protective grounding terminal to avoid electromagnetic interference.
