7.2.1 Opening and closing the Enclosure Cover
• Loosen the screws on the enclosure cover.
• If necessary, observe the cover lock at the rotary actuator.
• Carefully open or remove the enclosure cover.
• To close the enclosure cover, proceed in reverse order.
• Observe the specified tightening torque.
7.2.2 Making additional Through Holes
If additional drilled holes are required, for example for fastening cable entries,
breathers or other built-in parts in the enclosure, the following has to be observed:
• When determining positions of the drilled holes, observe the mounting distance to
ensure collision-free mounting.
• Space requirements result from the width across corners of the cable gland plus the
space required for the tool used to fasten the cable gland.
• Adjust the hole diameters to the dimensions of the built-in parts or their seals.
• Measure the dimensions on the flat surfaces on the inside of the enclosure,
not on the outside of the enclosure.
• Drill holes into the flat surfaces of the enclosure sides with interior and exterior
contours that run parallel.
• Additional holes can be drilled, lased or punched.
• During punching, make sure that the surfaces remain flat.
• Do not damage the circumferential sealing lips.
Optionally, rotary actuators attached to the cover may have a cover lock.
In this case, the cover can only be removed and locked in a specific position.
