4.2.4 Connection of the Output Supply Voltage
The supply voltage for the two output groups of 8 connections each can be
provided either internally using the supply voltage for the module, or exter-
nally from a separate power source. The base modules are provided with two
sets of terminal blocks in the middle row of the output terminals. The left-hand
terminal of each set carries the 24VDC module power, while the right-hand
terminal provides a connection point for the output supply voltage.
The base modules are shipped with jumpers installed in each of these termi-
nals, connecting 24VDC module power to connection point for the output
supply voltage.

The factory-installed jumper has to be removed when a separate power supply
for a group of 8 digital outputs is required. The separately fused or switchable
power supply is connected to the right-hand connection point.
