SWITCHESHINGE STYLESWITCHES WeightSI-QS75 models: 0.11 kg SI-QS90 models: 0.13 kg Application Notes Certifications Models with one and two contacts have three cable entry locations (bottom and two sides); models with three contacts have two cable entry locations (two sides). All entry locations are sealed with knockouts. To remove knockouts, thread the supplied M16 x 1.5 or M20 x 1.5 to ½" - 14 NPT conduit adapter or optional M16 x 1.5 or M20 x 1.5
cable gland into one of the threaded entry locations. The knockout will break open just before the adapter or cable gland bottoms out. For a list of certifications see page 238. Contact Configuration and Switching DiagramsSI-QS75 models: SD013 (p. 242)
