Procedure
Step 1 Secure the RS485 signal SPD to the guide rail, as shown in
Issue 12 (2019-01-15)
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.
