Alternative Ways of Connecting the Voltage Supply
The block diagrams relating to the ET 200L distributed I/O device will be
found in Chapter 7.
A labeling strip is located on the front of the electronics block for noting the
assignment of inputs and outputs.
A terminal connection model showing the terminal connection assignment
and electrical connections is located beneath the labeling strip on the elec-
tronics block (refer to Chapter 8).
Clip the bus connector on the electronics block.
1. Clip the bus connector on the PROFIBUS-DP terminal connection after
setting the PROFIBUS address of the ET 200L distributed I/O device (re-
fer to Section 2.6).
2. Tighten the fastening screws of the bus connector.
