2.3 Enclosure
The ATC eX NEMA controller has a modular design with all hardware interface located at the front panel:
Power switch, fuse holder, serial ports’ connectors, Ethernet and USB connectors, LCD, contrast control,
keypad and ACTIVE LED indicator are accessible from the front of the unit.
The top cover of the ATC eX NEMA controller is closed and free of any vent or openings to avoid dirt,
dust, water or other debris entering from the top of the unit. Ventilation holes are provided on the sides of
the unit in order to cool the electronics; the design is such that foreign debris and water cannot easily
enter case under normal operation and handling.
The controller is constructed so that it can be shipped easily via common carrier, such as the postal
service, UPS, or Federal Express, without damage and without disassemble or removal of internal
components or subassemblies.
