Procedure
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.
