Input Power Wiring
AC Power Wiring
The AC power wire size must be 26 to 16 AWG with the wire stripped 1/4 inch (6 mm).
Connect 100 to 240 VAC (0.2 Amps RMS at 230 VAC) to the neutral and line terminals
on the terminal block. Connect the ground wire to the safety ground lug. Torque all
connections to 4.43 to 5.31 in-lbs (0.5 to 0.6 Nm).
The Hazardous-Area enclosure has two separate conduit entries to maintain separation
between AC input power and output signal wiring. To eliminate the possibility of
noise interference, use a separate cable entry for the AC power and signal lines. See
Figure 11.
Figure 11: AC Input Power Connections
All wiring procedures must be performed with the power Off.
The AC wire insulation temperature rating must meet or exceed 80 °C
(176°F).
