ET 200X Distributed I/O Device
EWA 4NEB 780601602-06
Cables
Please refer to Section 4.4 and Appendix A for a list of suitable cable types.
Load supply voltage
If you use motor starters (EM 300...) and/or frequency converters, you must supply
them with 400 VAC (see Chapter 2.4).
Load power supply
If you use basic/expansion modules that have outputs, you must connect the
relevant ET 200X to a load power supply (see Section 2.5).
Exception: ET 200X-DESINA (see Figure 4-4).
2.3 Disconnecting ET 200X from the bus and looping through the
supply voltage/PROFIBUS-DP
(not ET 200X-DESINA/ET 200X-ECOFAST)
Looping through PROFIBUS-DP
The two connectors for feeding and looping through the supply voltage and
PROFIBUS-DP are plugged into a connector plate in the basic module. Remove
the two connectors from the BM 141/BM 142/BM 147 basic module of the ET 200X
together with the connector plate beneath them.
Advantage
The relevant ET 200X distributed I/O device is disconnected from PROFIBUS-DP,
but the supply voltage and PROFIBUS-DP are still looped through to the next ET
200X.
