2.4 Mounting - Completion

1. Remember to seal the 2N

Helios IP cable passage hole properly to avoid moisture

in-leak and damage to electronics due to condensation.

2. Make sure that the wires inside 2N

Helios IP are not squeezed and insert the

plastic top cover (a transparent plastic mould) carefully making its contacts plug

into the electronics board connectors. Push the plastic cover into position

moderately. If the part swings over an obstacle or one corner is higher than the

others, remove the cover and find the obstacle. Then tighten the corner screws

properly.

3. Mounting the metal sheet cover follow the steps included in the subsection

dedicated to name plate removal. Make sure that the cover fits well and is

perfectly flat. If its bottom part is loose, the mounting wall is probably uneven.

Support the corners to avoid 2N

Helios IP bending.

Caution

 An improper mounting may significantly deteriorate the button function.

 A poor outdoor mounting may cause water in-leak and damage to the

electronics.

Most Frequent Mounting Errors

For illustration, a part of the plastic cover is removed in the figures below to reveal the

sealed loudspeaker and the cover–seal touch point. The cross section plane is marked

white for better orientation.

(a squeezed wire has the same

effect)
