Introduction
1.2 Target Group, Personnel
Responsibility for planning, assembly, commissioning, operation, maintenance,
and dismounting lies with the plant operator.
Only appropriately trained and qualified personnel may carry out mounting, installation,
commissioning, operation, maintenance, and dismounting of the product. The personnel
must have read and understood the instruction manual and the further documentation.
Prior to using the product make yourself familiar with it. Read the document carefully.
1.3 Symbols Used
This document contains symbols for the identification of warning messages and of informative
messages.
Warning Messages
You will find warning messages, whenever dangers may arise from your actions.
It is mandatory that you observe these warning messages for your personal safety and in order
to avoid property damage.
Depending on the risk level, the warning messages are displayed in descending order
as follows:
Informative Symbols
Action
This symbol indicates a paragraph with instructions. You are prompted to perform
an action or a sequence of actions.
Danger!
This symbol indicates an imminent danger.
Non-observance will result in personal injury or death.
Warning!
This symbol indicates a possible fault or danger.
Non-observance may cause personal injury or serious property damage.
Caution!
This symbol indicates a possible fault.
Non-observance could interrupt the device and any connected systems and plants,
or result in their complete failure.
Note
This symbol brings important information to your attention.

2 Product Specifications
2.1 Function
Many applications in hazardous areas work with field devices that do not have
intrinsically safe connections. In these applications, protection methods such as type Ex e
protection (increased safety) are used. In contrast to intrinsically safe circuits,
increased safety connections are generally not accessible when energized. Disconnecting
these circuits for maintenance would therefore require either the plant to be shut down
or a hot work permit to be obtained.
The multifunction terminal offers the following options for disconnecting
non-intrinsically safe circuits or removing plug-in modules in hazardous areas:
•The multifunction terminals MFT-R.****, MFT-2R.****, MFT-D****(.L), MFT-2D.****,
MFT-F.****(.L), MFT-2F.****, MFT-2L.**** enable the non-intrinsically safe circuits
to be disconnected.
•The multifunction terminals MFT-FT.****, MFT-RNO.****, MFT-RNC.**** enable
the plug-in modules to be removed even in hazardous areas.
The non-intrinsically safe circuits are separated in 2 steps:
•Step 1
The electrical contacts between the base module and the plug-in module are separated
in areas protected by the type of protection Ex d.
In this position the sparks, that have formed within the contact area, can no longer ignite
the possibly existing surrounding atmosphere.
•Step 2
The plug-in module, which is now completely electrically isolated, can now be removed.
Possible ignition sources in the area of the electrical contacts are no longer present.
The electrical connections of the base module are protected and comply with degree
of protection IP30 according to IEC/EN 60529. After removal, the plug-in module
is de-energized.
•Once the plug-in module has been removed, the de-energized side is accessible.
This allows field devices that are connected to the de-energized side to be replaced,
while the remaining part of the system continues to be energized.
Typical applications for the multifunction terminal are:
•Fusing Ex d valves, signal lamps, acoustic sensors
•Diode decoupling of supply circuits
•Simple OR gate for Zone 1 mounting
•Visible disconnect of field devices
•Relay switch for power circuits
•Current limitation using resistors
•Optocoupler applications

Product Specifications
2.2 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.
