Mounting
The control panel is designed for installation on a mounting arm system. There are eight M6 x 20 threaded bolts on the back of the unit for mounting. The dimensions of the device can be found on the Beckhoff website: https://www.beckhoff.com/de-de/support/downloadfinder/technische-zeichnungen/. All dimensions are in mm.
Alternatively, you can mount the control panel on a mounting arm tube using a mounting arm adapter. Two adapter options from Beckhoff are available for this purpose, which are mounted ex factory:
Ordering option | Description |
|---|---|
C9900-M177 | Rotatable mounting arm adapter on Control Panel CP790x-140x or Panel PC CP770x-140x instead of 8 threaded bolts M6 x 20 mm. Stainless steel 1.4301, brushed. Mounting arm installation from below. |
C9900-M178 | Rotatable mounting arm adapter on Control Panel CP790x-140x or Panel PC CP770x-140x instead of 8 threaded bolts M6 x 20 mm. Stainless steel 1.4301, brushed. Mounting arm installation from above. |
Figure 10 shows the two available rotatable mounting arm adapters. Ordering option 1 is oriented for mounting from below. Ordering option 2 is oriented for mounting from above.
Mounting arm tube installation
The scope of delivery of the mounting arm adapters includes a connection piece and O-rings. This connection piece allows you to install a mounting arm tube on the mounting arm adapter. You must weld the connection piece (1) to the mounting arm tube (2).
Alternatively, you can order a ready-configured mounting arm tube with already welded connection piece from Beckhoff:
- C9900-M167: Adapter with welded tube (length: 1.50 m, diameter: 48 mm) for mounting arm adapter C9900-M177 or C9900-M178 on CP790x-140x Control Panel. Stainless steel 1.4301, brushed
Mounting arm installation
After you have welded the connection piece and the mounting arm tube together, you can mount the finished mounting arm on the mounting arm adapter. To do this, follow the steps below as shown in Figure 12:
- 1. Apply the supplied PTFE paste thinly to the O-rings and to the grooves for the rings on the connection piece using a brush or spatula.
- 2. Put the O-rings onto the connection piece (section A).
- 3. Unscrew the fixing screw of the mounting arm adapter completely (section B).
- 4. Push the connection piece into the mounting arm adapter as far as it will go (section C). Be careful not to damage the O-rings.
- 5. Screw the fixing screw back into the mounting arm adapter (section D).
- You have installed the mounting arm on the mounting arm adapter.
