Minimum clearances from earthed parts: 8 mm
Snap onto 35 mm standard mounting rail to DIN EN 50 022 or fix on a
plain surface with two M4 screws. With screw mounting, always use
plain washers and spring washers.
Cover the contactors during installation if foreign particles, such as
swarf, can fall onto them. Install contactors in a housing if they are
exposed to dirt, dust or aggressive atmospheres.
