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.
