Aminimum of two (2) mounting feet are required. Tabs areinstalled at locations so one tab is on the top and one onthe bottom of the device when mounted vertically.C445MB… and C445MC… Measurement Modules havemounting tabs molded into the housing assembly.Installation of panel mount screws on all mount tabs arerequired.The C445B… base module may be installed directly on top ofthe C445MA… Measurement Module by aligning the matingslots of the two devices and snapping them together. If thetwo devices are to be panel mounted, all four(4) panel mounttabs are required.Table 8. Mounting HardwareThe C445B…/C445MA… combined assembly may be mounted on a 35 mm DIN-Rail.C445 Surface Mounting on DIN railPlace the C445 device onto the mounting rail from above [1],push down [2], and allow the device to snap into position.To remove any C445 device from a rail, gently press down onthe unit and then pull the lower housing edge away from therail.
