Optional NEMA-housing
installation
An optional NEMA-4 (IP65) housing is available from the factory, or the
enclosure may be user-supplied.
Factory-supplied housing
If the RFT9709 is ordered with the factory-supplied NEMA-4 (IP65)
housing, Micro Motion installs the transmitter in the enclosure.
• Install the NEMA enclosure with four bolts. Micro Motion does not
supply mounting bolts.
• Mount to any flat, stable surface.
• NEMA housing dimensions are provided in Figure 1-3, page 6.
User-supplied housing
Any user-supplied NEMA-4 (IP65) enclosure of an appropriate size may
be used to house the RFT9709. Dimensions of the RFT9709 are
provided in Figure 1-2, page 4.
Conduit openings
Whether the optional NEMA housing is supplied by the user or the
factory, the user must add three conduit openings for power-supply
wiring, input wiring, and output wiring.
• Locate the housing so these openings are accessible for installation of
wiring and so the housing cover can be fully opened for access to the
RFT9709 inside.
• To help prevent moisture from entering the housing, install the housing
so conduit openings are pointed downward, if possible. To maintain the
enclosure’s NEMA rating, all conduit openings must be fully sealed
after wiring is installed.
• Recommended size for conduit openings is 3/4-inch (20 mm).
CAUTION
Failure to protect the RFT9709 from moisture could
cause a short circuit, which would result in
measurement error or flowmeter failure.
To avoid risk of condensation of excessive moisture in the
NEMA housing:
• Seal all conduit openings.
• Install drip legs in cable or conduit.
• Close and fully tighten all NEMA-housing covers.
