In Europe, the ATA2 must be powered from a Class II power source that is CE marked.

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

1When using 0.5 mm wire (24 AWG), select a location within 800 m (2600 ft.) of the BCM50.

2Allow 12.5 cm (5 in.) clearance for the line jack, terminal jack, and power supply connector.

3Screw two 4-mm (#8) screws into the wall, 130 mm (5 1/4 in.) away from each other. Leave 6 mm (1/4 in.) of the two screws showing.

4Align 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 Figure 50).
