The Allen-Bradley 1756-A10K 1756 ControlLogix chassis is designed on a horizontal rear panel component. The maximum ambient air temperature in this case is 60 °C (140 °F). The operating temperature of the chassis is -25-60 °C (-13-140 °F). The 1756-A10K weighs about 1.45 kg (3.2 lb). The minimum cabinet size of this chassis is 50.8 x 76.2 x 20.3 cm (20 x 30 x 8 inches). The Allen-Bradley 1756-A10K is designed for use in industrial environments. When used in a Zone 2 environment, the chassis is used in an environment polluted to 2 degrees (as defined in EN/IEC0664-1). The enclosure can only be accessed through the device. Do not disconnect the device unless the power supply is disconnected or the area is known to be free of danger.
Allen-Bradley 1756-A10K is an open device. This case should be installed in an appropriate housing designed for certain environmental conditions. To prevent damage from live parts, only tools can be used to enter the inside of the housing. The remainder of this publication may contain additional information about the ratings of special types of enclosures that must meet certain product safety certifications. Please refer to the NEMA Standard 250 and IEC 60529 publications, where applicable, for the level of protection provided by different types of enclosures.
