Push button extension cable routing

If you ordered the control panel with a push button extension, you must also connect it. If the device has a mounting arm adapter, the cable for the push button extension is first fed through the mounting arm adapter into the cable channel and then into the push button extension. Before you can lay the cables, you must open the cable channel and the push button extension (see chapter 4.2 Mounting).

Depending on the push button extension, the cable is either fed into the cable channel through an M20 gland or connected to a 19-pin round connector. The assignment is as follows:

Figure 31 shows the position of the M20 gland and the 19-pin round connector in the mounting arm adapter. In the case of the M20 gland, the device version is additionally decisive for the position of the cable gland.

In the case of a device with a connection block instead of the mounting arm adapter, the M20 cable gland or the 19-pin round connector is in a different position on the device (see Fig. 32).

You must carry out the wiring of the C9900-G02x push button extension yourself. To do this, feed the cables through the M20 cable gland and the cable channel into the push button extension.

Beckhoff takes care of the wiring of the C9900-G05x push button extension for you. Therefore you can order ready-to-use cables from Beckhoff Sales. For more detailed information on cable options and wiring diagram, refer to the C9900-G05x manual. You only have to plug the selected cable into the 19-pin round connector.
