3.1 General guidelines
Follow these guidelines when installing the rack-mount RFT9739
transmitter:
•Locate the transmitter where it is accessible for service and calibration.
•Install the transmitter in a location that is compliant with the area
specified on the RFT9739 approvals tag (see
Figure2-1
, page3).
•To comply with CENELEC standards for hazardous area installations in
Europe, the RFT9739 must be installed outside the hazardous area.
The transmitter installation must meet (at least) IP20 safety
requirements, per IEC 529.
•Total length of cable from the sensor to the transmitter must not exceed
1000 feet (300 meters).
•Locate the transmitter where the ambient temperature remains
between 32 and 122
°
F (0 and 50
°
C).
The rack-mount RFT9739 meets DIN standard 41494, 19-inch
configuration for control-room equipment.
•Transmitter dimensions are shown in
Figure3-1
, page12.
•Three transmitters fit into one 19-inch enclosure with a Eurocard
220mm depth, as indicated in
Figure3-2
, page13.
•When installing multiple transmitters in a single rack, 15 watts of
forced-air cooling, per transmitter, is required. Minimum spacing is
shown in
Figure3-3
, page14.
The back panel of the transmitter housing has two 32-pin connectors for
sensor wiring and output wiring. These connectors meet DIN standard
41612, Model F (male). For more information, see
Section3.2
, page15.
CAUTION
Failure to maintain an ambient temperature below
maximum temperature rating could result in
operational failure and product damage.
Install transmitter in an area with sufficient air flow to keep
the ambient temperature below 122°F (50°C).
