Installing the RS485 signal SPD
Context
- If the SmartLogger needs to be connected to outdoor equipment through the COM port, it is recommended that an RS485 signal SPD be installed.
- Each SmartLogger can be configured with a maximum of two RS485 signal SPDs.
- The RS485 signal SPD can be mounted on guide rail. No guide rail is delivered with an RS485 signal SPD. If you need to install an RS485 signal SPD on a guide rail, prepare a standard 35 mm wide guide rail with a length no less than 80 mm.
- Secure the guide rail before mounting the RS485 signal SPD.
- If the SmartLogger is installed on a guide rail, the RS485 signal SPD can share the guide rail with the SmartLogger. In this case, the recommended guide rail length is 400 mm or greater.
