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 through holes are required, for example for fastening cable glands,
breathers or other built-in parts in the enclosure, the following has to be observed:
• When determining positions of the through 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 and/or their seals.
• Measure the dimensions on the plane surfaces of the inner side of the enclosure,
not on the outer side of the enclosure.
• Make sure that the through holes are located on the plane surfaces of the enclosure
sides with parallel running interior and exterior contours.
• Additional through holes can be bored, laser-cut or punched.
• During punching make sure that the surfaces remain flat.
• Do not damage circumferential sealing lips.
7.2.3 Transport Protection for Holes
Open holes protected with an adhesive tape must be sealed by means of adapted and
certified components. Make sure that the adhesive tape is completely removed.
Rotary actuators installed on the cover may optionally be equipped with a
cover lock. In this case, the cover can only be removed or closed in one
specific position.
