Complete the following steps to mount the device to a DIN rail vertically by using the
unthreaded mounting holes.
1. Fasten a DIN rail clip to the device using a #1 Phillips screwdriver and four thread-forming
screws included in the DIN-rail mounting kit. Tighten the screws to a torque of 0.76 N · m
(6.7 lb · in.). Figure 5 shows a DIN rail clip being attached to the device.
2. Clip the device onto the DIN rail as shown in Figure 6.
Note Using the thread-forming screws permanently affixes the DIN rail clip to the
device. Unscrewing and reinstalling the thread-forming screws produces a
compromised connection between the DIN rail and the device.
