2.
Install a cable (to be field-supplied) that is permissible as electrical wiring of the remote
controller (→
4.7.2.1 External interfaces (J and H generation), p. 66
) from the terminals of
the indoor unit to the installation location of the remote controller.
3. Mount the cabinet bottom part (
2
) on the wall (
10
) (Fig.
D
), by screwing two self-tapping
screws (
11
) (to be field-supplied) into the wall through the two central openings (
12
) of the
cabinet bottom part. See that the bottom part is seated firmly.
4. Using pincer pliers, open the cable gland (
13
) at the top edge of the cabinet top part. Deburr
the edges of the cable gland so that the electrical wiring is not damaged.
5. Guide the electrical wiring of the remote controller (
5
) through the cable gland into the
remote controller and on the inside of the top part (
14
) along the edge up to the terminals of
the remote controller. Fasten the cable using cable binders (
15
).
6. Strip the insulation having a length of 6 mm from the wire end and ensure that the
connections of the electrical wiring point in the right direction.
7. Connect the electrical wiring of the remote controller to the terminals of the remote controller
(
9
) and the indoor unit (
