This device is suitable for outdoor and indoor use.
• Provide a protective roof or wall if enclosure and explosion protected electric
equipment is used outdoors.
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
NOTE
Material damage or malfuntion of the temperature sensor if mounted incorrectly.
• Mount and operate the device using suitable protective tubes. Exception: operating
medium air.
• Completely immerse the device into the operating medium
• For thermostats with capillary: sensor must be secured against sliding out by
means of a clamping bracket.
