Mounting arm tube installation
Observe the following points when installing the Control Panel on the mounting arm tube:
• For the correct installation height, use the position of the screen for guidance. This should always be
optimally visible to the user.
• Do not expose the Control Panel to direct sunlight.
The Beckhoff mounting arm adapters are designed for Rittal and Rolec mounting arm systems with 48 mm
tubes. The tube diameter may have a maximum tolerance of -0.1 mm and +0.8 mm.
If you have chosen a device with a mounting arm adapter, you must fit the mounting arm tube yourself. The
procedure for fitting the mounting arm adapters with upwards or downwards orientation is the same.
Among other tools you need a hook wrench for the installation. You can order this from your Beckhoff Sales
using the following order identifier:
• C9900-Z263: Hook wrench size 58-62 for tying up the slotted nut of the C9900-M75x mounting arm
adapter
Fig. 23 shows an example of the procedure with the mounting arm adapter facing downwards.
To install the mounting arm tube on the mounting arm adapter, proceed as follows:
1. Unscrew the Allen locking screw (1) a few turns with a 3 mm Allen key (section A).
2. Push the connection cables of the Control Panel through the mounting arm tube.
3. Insert the mounting arm tube into the mounting arm adapter all the way to the stop (section B).
4. Tighten the Allen locking screw again with a torque of 3 Nm.
5. Tighten the slotted nut of the mounting arm adapter with a hook wrench size 58-62 clockwise with a
torque of 20 Nm (section C).
