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.
