4.3.3 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 duct and then into the push button extension. You have to open the cable duct and the push
button extension before you can route the cable (see chapter 4.2
Mounting [ } 27] ).
Depending on the push button extension, the cable is either fed through an M20 cable gland into the cable
duct or connected to a 19-pin round connector. The assignment is as follows:
• C9900-G02x: Cable routing through an M20 cable gland
• C9900-G05x: Cable connection to a 19-pin round connector
Figure 28 shows the position of the M20 cable gland and the 19-pin round connector in the mounting arm
adapter. In the case of the M20 cable 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. 29).

You have to wire up the C9900-G02x push button extension yourself. To do this, feed the cables through the
M20 cable gland and the cable duct 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. More detailed information on the cable options and the wiring
diagram can be found in the manual for the
C9900-G05x . You only have to plug the selected cable into the
19-pin round connector.
