8.4.4 Connection Example
Connecting the load voltage supply
You can connect the load voltage supply of the analog module to the front
connector module. There are separate terminals on the front connector module for
the load voltage L+ and M. Observe the wiring rules in Table 8-3 on page 8-7.
Allocation of front connector to terminal block
The upper socket of the front connector module is the connection for terminal
block 1 and the lower socket of the front connector module is the connection for
terminal block 2.
Connection example
