Installation of these Neo-Dyn

®

 Enclosure 6N temperature 

switches is straightforward. However, they must be installed by a 
qualified electrician, in compliance with all local and national 
electrical codes. 

Electrical Hazard 

Do not make electrical connections while power is on. 

Always check for multiple circuits. 

Always make sure grounding is adequate. 

MOUNTING 

Model 100T can be mounted directly to the process connection if 
there is no significant vibration and the fluid lines are capable of 
supporting the weight. It can also be attached to a flat surface, 
such as a wall or panel, using .250 in. diameter or M6 socket-head 
cap screws through the mounting holes that are accessed by 
removing the housing cover; allow .5 in (12.7 mm) screw length 
above the mounting surface. These holes are located on two 
corners of a 2.72 inch (6.91 cm) square, or 3.85 inches (9.77 cm) 
apart on a 45° diagonal. Model 100TC must be mounted by this 
method, as its remote temperature sensor will not support the 
housing. Do not overtighten the screws when replacing the cover.
