4.2 Fastening on a mounting surface
While pressing the latch (4) in the base of the device (Fig. 5,
left) pull out the isolating amplifier securing brackets (1). To
return the brackets to their original positions, the latch (5) in
the base of the device has to be depressed before applying
pressure to the securing brackets (1) (see Fig. 5, right).

(2) Top-hat rail clips
(3) Rubber buffers
(4) Latch for pulling the screw hole
brackets out
(5) Latch for pushing the screw hole
brackets in.
Drill 2 holes in the wall or panel as shown in the drilling pattern
(Fig. 6). Now secure the power pack to the wall or panel using
two 4 mm diameter screws.
