INSTALLATION
General Requirements
Refer to the environmental specifications found in Table 1for recommended site conditions.
It is not recommended to install the SM-IO2 in such a manner that it remains exposed to direct sunlight.
Ventilating openings must not be blocked and temperature of air entering the SM-IO2 must not exceed the
rated operating ambient temperature range (see Table 1).
Installation Methods
Provided with the SM-IO2 are two (2) wall mounting brackets, two (2) wall mounting bracket screws with flat
washer (can also be used to mount SM-IO2 to rack), two (2) wall mounting expansion anchors, and two (2) wall
mounting anchor screws.
Wall Mounting
The SM-IO2 is mounted on a wall using the two (2) wall mounting brackets shown in Figure 3.
Figure 3: SM-IO2 (Top View) Showing Wall Mounting Brackets
Procedure
The following procedure outlines steps to mount the SM-IO2 to a suitable wall using the expansion anchors
provided with the SM-IO2. If other anchors or wall mounting methods are used, it is up to the installer to be
familiar with the installation requirements and techniques to be used in securing the SM-IO2 to a suitable wall
using these other anchors or methods.Ensure that the wall and fastening technique are suitable for supporting
the weight of the SM-IO2.
1. Install the furnished wall mounting brackets to the SM-IO2 (using the furnished hardware) as shown in
Figure 3.
2. Temporarily place the SM-IO2 on the wall in the desired mounting location. Use a pencil and mark the
location of the wall mounting holes in the center of the slots on the wall mounting brackets. Remove the
SM-IO2 from the wall.
3. Drill M6 (6 mm) holes in the wall at the locations marked to a depth of 60 mm (approximately 2.36
inches).
Wall Mounting Brackets

4. Insert a furnished expansion anchor into each hole drilled. Gently hammer each anchor until the top is
flush with the wall.
5. Place the SM-IO2 onto the wall, aligning the mounting holes in the wall mounting brackets with the
expansion anchors just installed.
6. Secure the SM-IO2 to the wall by screwing the furnished M6 X 60 mm screws with furnished flat
washers into the wall mounting anchors. The minimum torque is 50 Nm (36.88 ft-lbs) and the maximum
torque is 80 Nm (59.00 ft-lbs).
Rack Mounting
The SM-IO2 can be mounted vertically or horizontally in a rack. The SM-IO2 is mounted in a rack using the rack
mounting holes provided in the sides of the SM-IO2. Screws are furnished with the SM-IO2 to either mount the
wall mounting brackets to the unit or to be used to secure the unit to a rack.
Procedure
1. Slide the SM-IO2 into the rack.
2. Align the SM-IO2 rack mounting holes with the desired holes in the rack
3. Secure the SM-IO2 to the rack with the furnished screws and washers.
