Mounting and connecting the HMI device
4.3 Mounting the device
Procedure
This section describes the mounting of the device to a support arm system. Installation on a
pedestal is carried out in the same way.
For devices of the type "suitable for support arm", the base adapter is screwed to the device
from the top; for devices of the type "suitable for pedestal", it is screwed from below.
A device for a support arm system cannot be used on a pedestal, and vice versa.
NOTICE
Observe the torques
If you apply too much torque to tighten the screws of the backplane cover and the terminal
compartment cover or the screws for fastening the device to a support arm or pedestal, the
threads of the enclosure, intermediate plate or support arm may be damaged.
If you tighten the screws with a torque that is too low, the device is not sealed.
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.
