These enclosures are designed specifically to house HMI and electronic controls, instruments and components. The front cover is easy to remove, facilitating installation of cutouts and HMI. The rear door is hinged and secured with a quarter-turn latch and has provisions for sub-plate on the door for access in the final installation. The suspension system is designed for use with SCE HMI enclosures and allows operators to move or position an HMI easily to an ergonomic and comfortable working position. The system can be assembled in many configurations that allow for machine-, wall-, top- and floor-mount options.
