Pointed or sharp tools
If unsuitable tools are used, they can scratch the housing or damage the seal, and thus have a
negative impact on the leak-tightness of the housing.
‣ Do not use any sharp or pointed objects, such as a knife, to open the housing.
‣ Only use a suitable Phillips screwdriver.
‣ Release the housing screws step by step. Start with any screw and then release the screw
diagonally opposite etc.
‣ When closing the housing, also tighten the screws step-by-step in a diagonally opposite
sequence.
