Wiring The Et 200M - Siemens SIMATIC ET 200M Operating Instructions Manual

2.1.3

Wiring the ET 200M

Mounting rail
1. Connect the rail to the protective conductor. An M6 screw is provided on the rail for this
purpose.
Minimum cross-section from the conductor to the protective conductor: 10 mm
Power supply and IM 153-2
1. Open the front doors of the PS and IM.
2. Undo the strain-relief assembly on the PS 307. Strip the power supply cable.
3. If necessary, attach wire end ferrules (in the case of multi-conductor cables). Then connect
to the PS 307 (see the following figure).
4. Screw the strain-relief assembly tight.
5. Insert the jumper in the PS 307 and the IM 153-2 and tighten it (refer to following figure).
6. Check that the switch for selecting the mains voltage is set correctly to your mains voltage
on the PS 307.
The power supply module is factory-set to a mains voltage of 230 V AC. You can change
the setting in the following way: Remove the protective cover using a screwdriver, set the
switch to the available mains voltage and reattach the protective cover.
7. Insert the PROFIBUS DP cable between the DP master (2nd DP interface) and the IM 153-2.
The terminating resistors in both connectors must be switched on.
Front Connectors of the DI and DO
1. Open the front doors of the DI and DO.
2. Move the front connector to the wiring position:
To do so, push a front connector into each DI and DO until it engages. The front connector
still protrudes from the module in this position. In the wiring position a wired front
connector has no contact with the module.
3. Strip 6 mm of insulation off the ends of the wires you want to insert into the front connector
and then attach appropriate wire end ferrules to the wire ends.

WARNING
You could touch live wires if the power supply module PS 307 is switched on or the
supply cable of the power supply is connected to the mains supply.
Make sure the ET 200M is de-energized before doing any wiring.
