3.5 Installing the RS485 signal SPD

Context


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. For details about the guide rail dimensions, see Figure 3-8.

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 RS485 signal SPD can connect to two COM ports. Each SmartLogger can be
configured with a maximum of three RS485 signal SPDs.
For a smart array controller, the RS485 signal SPD is installed before delivery. In other
scenarios, the RS485 signal SPD can be mounted on guide rail.
When determining the installation position, verify that the linear distance between the RS485 signal SPD
and the SmartLogger is no greater than 500 mm.
