Installation
3.1
Storage and transportation
For storage and transportation, the multiplexer must be protected from shock loading and dampness by me-
ans of suitable packaging. Optimum protection is afforded by the original packaging.
In addition, the permissible ambient conditions must prevail (see datasheet).
3.2
Unpacking
Make sure that the multiplexer is undamaged. Damages should be reported to the mail or forwarding agent
as well as the supplier.
The consignment should be in compliance with the order and shipment documents. Check the following
items:
•
Quantity supplied
•
Device type and version in accordance with the type plate
•
Accessories (manual, etc.)
Keep the original packing if the device is to be stored and shipped at a later date.
3.3
Installation
The installation options are described in the accompanying product information about the K-System, KFD
series.
3.4
Electrical connection
3.4.1
General notes for connection
Work on live installations and electrical connections must only be carried out by appropriately
trained personnel.
When connecting the RS 485, reference should be made to the instructions in section 2.1.13 .
3.4.2
Location of electrical connections
The power supply (24 V DC nominal voltage) is provided via the power rail or terminals 1 7(+) and1 8(-).
The device is protected against reverse polarity by means of a protection diode.
The connection of a higher level control unit (PLC, PC) is achieved via an RS 485 interface on terminals 13,
14 and 15. The RS 485 bus is looped through to terminals 19, 20 and 21. In this way, the three terminals
can be used alternatively, or simultaneously, (for the connection of other devices with R S485, or for the
connection of a terminating resistor). If a standard PC with an RS 232 interface is to be used, an interface
converter is required (see section 2.1.2).
The connection of the KFDO-HMS-16 HART Multiplexer slaves is via the 14 pin plug connector on the side
of the device.
The analogue HART signals are connected to the current repeaters via the 26 pin plug connector on the
front of the device.
Subject to reasonable modifications due to technical advances.
