Colored strips located at the sides of the 4mm, antistatic, tempered, smoothed glass door, having an extruded aluminum frame and high fracture resistance, present a decorative view. In free-standing type applications, they may be used with optional pinion feet or caster groups. By attaching a ventilation module with a maximum of 2 fans (optional) to the ventilation hole at the upper chassis of the cabinet, active ventilation is achieved. If no fan module is attached, these ventilation holes enable air circulation inside the cabinet and the discharging of hot air by passive ventilation. Since the side doors are fixed and not detachable, access to the cabinet is ensured only from the front in wall mounting applications and from the back and front in free-standing applications. The standard cabinet is delivered with 1 set and 2 device installation rails mounted. Device installation rails enable depth adjustments of the devices to be applied into the cabinet. With 145mm x 70mm cable inlet holes at the upper, lower, and rear door of the cabinet, it provides cable inlet in 3 directions, facilitating installation. Thanks to the rubber-edged cable entry module, movable for 0-50 mm and with a sliding compression system, incoming cables are compressed safely while minimizing dust inside.
