Step 2 Wiring
2.1 General guidelines
Figure 2-1 illustrates the locations of the terminals for power-supply
wiring, wiring to the sensor, and output wiring.
• Terminal blocks may be unplugged from the RFT9709 (after removing
two screws) for easier installation of wiring. Always tighten screws after
re-installing terminal blocks.
• Install all conduit, cable and wiring to meet local code requirements.
For an RFT9709 installed in a NEMA enclosure:
• The RFT9709 may be installed in a user-supplied or factory-supplied
NEMA-4 (IP65) enclosure, as described in Section 1.4, page 5. The
enclosure requires three separate conduit openings for power-supply
wiring, sensor wiring, and output wiring.
• Conduit openings must remain sealed to maintain the NEMA-4 (IP65)
rating. Use conduit seals or cable glands that provide a complete seal
with the conduit openings.
