2.2 Mechanical Installation

2N^® Access Unit M is designed for surface or flush mounting. Electrical mouting boxes for cable connection and placement under the unit are available in both the surface and flush versions. These boxes are not part of the main unit package.

General Mounting Principles

Tip

You are advised to purchase the flush mounting boxes in advance and commission a building company to do the masonry for you, for example.

Caution

Before starting the mechanical installation on a selected place, make sure carefully that the preparations associated with it (drilling, wall cutting) cannot damage the electrical, gas, water and other existing wires and pipes.
The warranty does not apply to the product defects and failures arisen as a result of improper mounting (in contradiction herewith). The manufacturer is neither liable for damage caused by theft within an area that is accessible after the attached electric lock is switched on. The product is not designed as a burglar protection device except when used in combination with a standard lock, which has the security function.
Shortening of the LAN cable in Part Nos. 9161121, 9161141, 9161151, 9161161 shall not result in a loss of warranty.
When the proper mounting instructions are not met, water might get in and destroy the electronics. The circuits are constantly under voltage and water infiltration causes an electro-chemical reaction. The manufacturer‘s warranty shall be void for products damaged in this way!
Make sure that the diameters of the dowel holes are accurate. If the diameters are too large, the dowels may get loose. Use the mounting glue to secure the dowels if necessary.
Make sure that the depths of the dowel holes are accurate!
Make sure that the mounting surface is flat with a maximum inequality of 0.5 mm. (e.g. prefabricated boards, glass, cut stone, etc.). If this is not the case, level the wall surface.
Any intentional mechanical damage to the device (drilling, main unit tampering, etc.) results in a loss of warranty.
