Instrument wiring diagram

Specifications for A, B, C, D, E type wiring diagrams

Note: The terminals of the rear cover of the horizontal and vertical meters are not the same. See diagram 1:

Specifications are F-type wiring diagrams

Specifications are H type wiring diagram

Note: The orientation of the terminals on the rear cover of the horizontal and vertical meters is different, see diagram 1. Note: In the above wiring diagram, if different functions are marked in the same group of terminals, only one of them can be selected. For example, RS485 communication function and transmission output function are on the same group of OUT terminal, only one kind can be selected.
