CONTROLLER ENCLOSURES
PANEL MOUNT
The Merrick MC³ Panel Mount Controller is
designed for mounting in a control cabinet.
It is suitable for use in environments that
are generally clean, and within the
temperature range of 32
o
to 104
o
F (0
o
to
40
o
C). It must be protected from water or
significant dirt or dust. See the drawings
provided in Appendix A (page 49) for exact
specifications on the controller enclosure.
The panel mount enclosure consists of a
rectangular box with a hinged door on the
rear covering the I/O connections, a
removable top cover, a system-grounding
bar and a sliding tray. The slide tray allows
the Card Stack Assembly to be slid out of
the back of the enclosure for easier
maintenance while the controller is mounted into a panel. The Display assembly is mounted on
the front bezel. The top cover may be removed for easier access to the boards. Access to the
terminal blocks for interconnection with other equipment is obtained by unscrewing the rear
cover.
WALL MOUNT
The Merrick MC³ Wall Mount Controller
is designed to be weatherproof, and can
be mounted most anywhere. The
temperature range of this controller is
within 14
o
to 122
o
F (-10
o
to 50
o
C).
Merrick recommends that the controller
should be located out of direct sunlight
and away from dripping water and must
be protected from heavy rain. Refer to
the drawing in Appendix A on page 51
for detailed specifications of the
controller enclosure.
The wall mount enclosure is available in
NEMA-4, NEMA-4X or NEMA-12 boxes.
NEMA-4 box includes gaskets and a
window kit over the touch screen to
provide extra protection. NEMA-4X will
provide a stainless steel enclosure and
window kit.
