5.3.2 Connecting Several Modules Mechanically
As ETAS system housing was used, the ES910.3-A can also be connected to
modules of the ETAS compact line (ES59x, ES6xx, ES930) providing certain con-
ditions are adhered to (see chapter 5.2.2 on page 43). These can be combined
easily using the T-Brackets provided to form larger blocks.
ES910.3-A modules can only be connected vertically to other modules.
If the ES910.3-A is to be connected with modules of the ETAS compact line, the
latter must not be positioned to the side of the ES910.3-A as this would mean
insufficient exchange of heat.
You can attach a further module of the ETAS compact line under the ES910.3-A.
Just remove the four plastic feet on each of the relevant device sides and attach
the T-Brackets provided in their place.
CAUTION!
The electronic can be damaged or destroyed! 
Do not rework the threaded hole.
Note
Use excluding M3 cylinder screws and fastening the module onto your carrier
system with a max. torque of 0.8 Nm.

The max. length of engagement into the tapped blind hole of housing is 3 mm
(see Fig. 5-3 on page 45).
CAUTION!
Heat concentration on the long sides of the module. 
The electronics can be damaged due to overheating. 
Do not cover ventilation slits when setting up, assembling or connect-
ing with other modules. Adhere to the minimum distance at the sides.
