NOTICE
Damage to the housing
The housing of the HT 8 is made of plastic. Therefore, the mounting hole threads cannot handle
the same amount of stress as a comparable metallic housing. Therefore, do not exceed 0.4 to
0.5 Nm of torque when tightening the screws (also for protecting the connecting cable).
If you use a power screwdriver, ensure the max. speed of 600 rpm is adhered to (torque: 1 Nm).
The screws of the cover may only be loosened or tightened a maximum of 20 times. Otherwise,
there is the danger that the threads might become damaged and the seal of the housing will
be compromised which could lead to failure of the device.
