ABB 5730030-UN Channel relay module

The device is designed for mounting in control cabinets, control panels or control desks. 10.4" and 12.1" devices can be mounted horizontally or vertically, 15" devices must only be mounted horizontally. The following requirements must be fulfilled when selecting a suitable mounting position:  The device should not be exposed to direct sunlight (Sunlight disturbs the infra-red touch sensor. In addition, when exposed to UV light, plastic parts of the device can embrittle and the lifespan of the device is reduced).  If the device is to be used in potentially explosive atmospheres, the device must not be subjected to hazardous knocks.  The operating elements on the service side of the device and the cable connections are accessible after the device has been mounted.

 The ambient conditions stated must be observed. See Chapter 9.9 Ambient conditions

 Sufficient ventilation (cooling) must be ensured by means of:  Clearance of at least 3 cm to the ventilation slots  Clearance of at least 15 cm from heat radiating components such as heavily loaded transformers  The expected temperatures should be within the permissible range. See Chapter 9.9 Ambient conditions,  62.  Properties of the mounting surfaces:  Material thickness at the mounting cutout 2…5 mm 

 Flatness  0.5 mm (this requirement must also be fulfilled when the device is mounted!) 

 Surface roughness Rz  120
