Part number:

This FAQ applies to the SINAMICS G120 Control Units without “-2” in the product name. 

Please note
This FAQ only works for the IOP, it does not apply to the BOP-2!

The IOP can be used together with the CU240S..., CU240E in two different ways.

1. The IOP can be connected to the CU240S..., CU240E via IOP Handheld.

What do I need?

  • IOP Handheld (order number: 6SL3255-0AA00-4HA0)
  • PC-Connection Kit for CU240S/E (order number: 6SL3255-0AA00-2AA1) 

2. The IOP can be used as a door mounted option with the CU240S..., CU240E control units, but only with an additional cable and an external power supply for the IOP.

What do I need?

  • IOP (order number: 6SL3255-0AA00-4JA0)
  • Door Mounting Kit for the IOP (order number: 6SL3256-0AP00-0JA0)
  • PC-Connection Kit for CU240S/E (order number: 6SL3255-0AA00-2AA1)
  • "Knorrtec" Connection Cable for CU240S/E, connecting the external power supply of IOP (order number see PDF)
  • External DC +24V, (e.g. SITOP PSU100C; order number: 6EP1331-5BA00)

Do not connect 24V DC directly to the IOP, or demage will result!

The "Knorrtec" connection cable is fitted with a DC/DC coupler (with galvanic separation, 24VDC, 50 mA) to allow the use of a external +24V DC power supply.
Wiring and cable specification, contact details and order number can be found in the attached PDF-file.
The responsibility for this cable lies with the Siemens solution partner Knorrtec.
