4.7.2.4 Terminal block with potential distributor (M potential)
General pin assignment with potential distributor
● The pin assignment on the left side of the terminal blocks with a potential distributor should
be set in accordance with the configured I/O module.
● 36 M terminals are located on the right side of the potential distributor.
Note
Connection information
● The M terminals on the right side are intended exclusively for the loads connected to the I/
O using 2-wire connection system. You may not use these terminals as the ground terminals
for other devices in the system.
● Ensure that the total current does not exceed 10 A.
