for the installation of HIBUS-2 (RS 485)
Figure 1: Wiring diagram, top view, front view
The bus terminal consists of a 25-pole Min-D socket to connect single channel PES and re-
dundant PES H41q/H51q via the data cables BV 7040 or BV 7046.
The connections for the 2-wire bus are made by means of two 6-pole terminal blocks. By se-
lection of two switches the bus terminating resistors can be switched on at each end of the 2-
wire bus. If the bus terminal block H 7506 is used at the end of the 2-wire bus then the terminal
block X2 cannot be connected.
Use of the bus terminal H 7506 see the following application and the applications in data sheet
