Mounting the ATA2
After the ATA2 is correctly connected, you can mount the unit on a wall as described in this
section.
To mount the ATA2 on a wall
1 When using 0.5 mm wire (24-AWG), select a location within 800 m (2600 ft.) of the BCM50.
2 Allow 12.5 cm (5 in.) clearance for the line jack, terminal jack, and power supply connector.
3 Screw two 4-mm (#8) screws into the wall 130 mm (5.25 in.) apart. Leave 6 mm (0.25 in.) of
the two screws showing.
4 Align the slots at the back of the ATA2 unit over the screws. Push the unit against the wall. The
line jack, terminal jack, and power supply connector must be at the top of the ATA2. See the
figure
ATA2 back view on page 122.
