Installation Manual for SMX Modules - OEM Automatic AB

Installation Manual
4.2 Installation and assembly of the SMX module
The module is solely to be installed in control cabinets with a degree of protection of at least
IP54.
The modules must be vertically fastened on a top hat rail
The ventilation slots must be kept unobstructed, to ensure adequate air circulation inside the
module.
4.3 Installation of backplane bus system
Mounting several SMX modules (SMX10, SMX11, SMX12, SMX12A) on one top hat rail in
connection with the backplane bus system is also possible. These modules can be combined
with a communication extension. In this case the backplane bus system needs to be
configured by BBH when placing the order and delivered in accordance with the application
in question.
The backplane bus system consists of a 5-pin plug connector with snap-in contacts. In these
plug connectors all 5 contacts are equipped by standard. In this case the component is not
specially marked. On a second variant of the plug connector only 3 contacts are equipped.
Note:
Expansion modules have no own power supply unit and depend on a DC power supply via
the backplane bus system. Base modules (SMX10, SMX11, SMX12, SMX12A) are equipped
with a reinforced power supply unit and always feed in to the backplane bus.
There are two different types of backplane bus connectors:
• TB1: Standard design (all contacts are present)
• TB2: Interrupter design (the two power conductors are not present and are marked
with a green dot)
Using the backplane bus connector TB1:
The backplane bus connector TB1 can only be installed in connection with expansion
modules without their own power supply. Connection of several standalone modules is not
possible.
Using the backplane bus connector TB2:
The backplane bus connector TB2 is used for combining several base modules with
expansion modules. A detailed description can be found under point 4.3.1.
