You may need screw anchors if mounting on a concrete or brick wall.

The following are the wall-mounted installation requirements:
• Use screws with 6 mm – 8 mm (0.24" – 0.31") wide heads.
• See the following table for how far apart to place the screws.
The following figure shows the screw specifications used for wall mounting.
• D = 7.00 mm
• H = 2.00 mm
• L= 15.50 mm
• d = 3.50 mm
Do the following to attach your Switch to a wall.
1 Select a position free of obstructions on a wall strong enough to hold the weight of the Switch.
2 Mark two holes on the wall at the appropriate distance apart for the screws.
WARNING ! Be  c a re ful to  a vo id da m a g ing  pipe s o r c a ble s lo c a te d inside

3 If using screw anchors, drill two holes for the screw anchors into the wall. Push the anchors into the full 
depth of the holes, then insert the screws into the anchors. Do not insert the screws all the way in - leave 
a small gap. The gap must be big enough for the screw heads to slide into the screw slots and the 
connection cables to run down the back of the Switch.
If not using screw anchors, use a screwdriver to insert the screws into the wall. Do not insert the screws all 
the way in – leave a gap.
