NOTICE
Damaging the seal when opening
If the device has not been opened for a long time, the backplane cover and terminal
compartment cover may stick to the enclosure caused by the seal. Opening the device
with excessive force or with tools will destroy the seal. Spray and water jets as well as
penetrating substances can then damage the device.
Open the terminal compartment cover gently, without too much pressure.
NOTICE
Observe the torques
If you use 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 stand, 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.
