Wiring diagram

Note 1: If different functions are marked on the same group of terminals in the wiring diagram, only one function can be selected. If RS485 and RS232 are connected to the same set of terminals, only one can be selected.

Note 2: The direction of the wiring terminals on the back cover of the horizontal and vertical instruments is different, as shown in Figure 1.
