Physical Considerations

The controller can be mounted on either a vertical or tilted panel
using the mounting kit supplied. Adequate access space must be
available at the back of the panel for installation and servicing
activities.
The controller must be installed indoors.
n
It must be panel mounted with the wiring terminals enclosed
n
within the panel.
The instrument is environmentally hardened and, when suitably
n
enclosed, can be mounted anywhere in plant or factory, on the
wall, or even on the process machine itself.
The front panel is moisture rated NEMA3R and IP54 rated and
n
can be easily upgraded to NEMA4X and IP66 for the most severe
hose-down applications. See
Procedure for more information.
It withstands ambient temperatures 0 ~ 55 C (32 ~ 131 F) and
n
resists the effects of vibration and shock.
Overall dimensions and panel cutout requirements for mounting
n
the controller are shown in figure below. See Overall Dimensions
for more information.
The controller's mounting enclosure must be grounded according
n
