Assembly

The multifunction terminal consists of a base module and a plug-in module. The base module
is mounted on a DIN mounting rail. The plug-in module is connected to the base module.
The base module has a plastic housing that conforms to type of protection Ex e.
There are 2-pin and 4-pin base modules for connecting plug-in modules with 2 or 4 pins.
The plug-in module has a plastic housing with type of protection Ex d. The plug-in module has
pins. The pins form together with the plug-in module contacts a chamber in type of
protection Ex d.
The plug-in module can be equipped with various components, such as resistors, diodes,
fuses, or relays. The plug-in module can be removed or connected during operation.
Grooves of different widths ensure that the plug-in module is connected
to the base module correctly.
A coding strip in the base module and corresponding coding pins in the plug-in module enable
clear assignment of the plug-in modules to the base module.
Screw terminals and unused terminal openings can be covered with IP30 covers in the form
of terminal covers and terminal pins, so that no bare, conductive parts are left uncovered.
These covers will be fitted during installation and must not be removed during operation.
