Installing and connecting the device
3.3 Mounting the PRO device
Procedure
This section describes the mounting of the device to a support arm system using example
figures. Installation on a pedestal is carried out in the same way. With PRO devices for
support arm (not extendable, flange top), the basic adapter is screwed to the device from the
top. With PRO devices for pedestal (extendable, flange bottom), the basic adapter is
screwed to the device from the bottom. A device for a support arm system cannot be used
on a pedestal, and vice versa.
1. If an adapter plate for the Siemens base adapter is included in your support arm system,
attach the adapter plate to the support arm with 4 M6x12 screws. Pay attention to the
torque that is specified for the support arm.
2. Attach the base adapter with 4 M6x12 screws to the mechanical interface of the support
arm from below. Pay attention to the torque that is specified for the support arm.
3. Loosen the 8 screws of the backplane cover and remove the backplane cover.
