Installation (N4X Enclosure)
2.1 Mounting
Securely mount the Model SW-HMI-32-N4X per the mounting dimensions provided in Figure 8. Provide
for suitable conduit/cable entries in the bottom, top or sides of the enclosure and use required cable glands
to maintain enclosure rating. Keep AC power separate from DC power and signals within conduit runs.

2.2 Power & Modbus Connections
The SW-HMI-32-N4X remote display can be powered by either 110/220VAC or 11.5-30VDC. An internal
power supply is available for the SW-HMI-32-N4X that converts 110/220VAC to 24VDC (up to 2.5
Amps) and can power an RXT-300 transceiver plus up to eight serial sensors. Optionally, the SW-HMI-
32-N4X can be powered by an external DC power source that meets the input requirements of the unit if
AC power is not available or desired.
The SW-HMI-32-N4X remote display includes a primary Modbus™ interface (COMM1 Master) used to
receive concentration and status directly from its RXT-300 transceiver (Slave) as well as a secondary
Modbus™ interface (COMM2 Slave) which is used for communication with another remote display where
the SW HMI is seen as a slave device.
2.2.1 AC Power Input
Connect 110/220VAC input wiring to the terminals of the DIN rail mounted terminal block labeled “VAC
(L1)”, “NEU (L2)”, and “GROUND” (See Figure 9). The power supply for the SW-HMI-32-N4X is
capable of handling AC inputs from 100-240VAC, 45-65Hz without degradation and can power up to eight
serial sensors.
NOTE: The input voltage range must be between 100-240VAC. All wired Modbus™
devices connected to the SW-HMI-32-N4X must have a common ground.
