Delivery, transport and storage

The KFD-HMM-16(referred to as "Multiplexer Master" or "Multiplexer" in the
following sections) and the KFD0-HMS-16 (referred to as "Multiplexer Slave" or
"Multiplexer" in the following sections) provides full HART access to up to 256 field
devices and hence operation with the conventional 4 mA ... 20 mA current loops. It
thus acts as a transparent gateway between the service station (PC or PCS (Process
Control System) and the transmitters.
The Multiplexer can be used within zone 2 hazardous areas or in the safe area.
Power is provided by a 24 V (nominal voltage) DC power supply. Connection to the
PCS or PC is via an RS 485 interface.
It should be stressed that the Multiplexer is approved for use in zone 2 and
therefore may not be used in zone 0 or 1 hazardous areas. If the equipment is used
in conjunction with intrinsically safe or associated apparatus, then this use must
take place in front of the Ex-barrier (e. g. transmitter power supply device).
Reference should be made to the statement of conformity.
The following identification is affixed to the Multiplexer Master:

The device must not be cleaned with caustic fluids.
The devices are maintenance-free. However, to guarantee perfect operation of the
complete system, check the operation, including all system parts, at least once a
year.
Check the packaging and contents for damage. In the event of damage, notify the
postal service or express agent and inform the supplier.
Check the scope of supply for completeness and correctness using the order and
delivery papers.
Keep the original packaging.
The device should always be stored or transported in the original packaging.
Always store the device in a dry and clean environment. Observe the permissible
storage temperature (see data sheet).
