WALL MOUNT
For many industrial applications, you will find it convenient to mount NPort Express on the wall, using two screws, as
indicated below.
1. Screw two screws, separated by 7.8 cm, into the wall. The heads of the screws should be no greater than 6.5 mm in
diameter, and the shafts should be no greater than 3 mm in diameter. Do no screw the screws in all the way. Leave a
space of about 2 mm to allow room for sliding the NPort Express unit's ears between the wall and the screws.
