2. Installation
2.8 Special conditions for
safe use
•
The intrinsic safety output terminals are located in the same room as the input terminals and the
final installation shall secure the spacing of 50 mm between the intrinsic safety terminals and the
non-intrinsic safety terminals. To prevent mixing of cables between intrinsically safe terminals an
all other terminals, a isolating plate is mounted in the terminals room.
•
The signal converter shall always be connected to ground using the internal terminal.
•
The code number FDK:083H0202, FDK:083H0203, FDK:083H206 and FDK:083H0207 shall be
installed in a 19" rack with an ingress protection of at least IP 20.
•
For IP 65 Siemens Flow Instruments code number FDK:083F5037 can be used.
•
On the connection board are terminals marked „No wiring connections“. These terminals are not
for field wiring but only for connection to MASS 6000 SENSORPROM

.
•
The 24 V input voltage for the 24 Volt version shall be from a safety-isolated transformer according
to EN 60742 or EN 61558-1.
