Installation
Considerations
For dimensional drawings, see “Dimensional Drawings” on page A-6.
Battery Side of Electronics Housing
Mount the switch so that the battery side is accessible. Clearance of
2
3 /
8
in. (60 mm) is required for cover removal.
Circuit Side of Electronics Housing
Provide 0.75 in. (19 mm) of clearance for units without an LCD display. Three
inches of clearance is required for cover removal if a LCD display is installed.
Cover Installation
Always ensure a proper seal by installing the electronics housing cover(s) so
that metal contacts metal. Use Rosemount O-rings.
LCD Rotation
In addition to housing rotation, the optional LCD display can be rotated in 90°
increments by squeezing the two tabs, pulling out, rotating and snapping back
into place.
NOTE
If LCD pins are inadvertently removed from the interface board, carefully
re-insert the pins before snapping the LCD display back into place.
Grounding
Always ground the housing in accordance with national and local electrical
codes. The most effective grounding method for the housing is a direct
connection to earth ground with minimal impedance.
Housing Rotation
The housing can be rotated for optimal viewing of the optional LCD display
and to get the best antenna position. Perform the following procedure:
1. Loosen the housing rotation set screw (Figure 3-2).
2. First rotate the housing clockwise to the desired location. If the desired
location cannot be achieved due to thread limit (up to 360°), rotate the
housing counter-clockwise to the desired location.
Do not over twist .
3. Re-tighten the housing rotation set screw.
