Series GEN 2 Ultrasonic Humidifier IOM Manual
Single Humidifier
Once the
Ultrasonic Humidifier and control box are installed, the total 48VDC wire length and wire size
(AWG) should be determined using the table below. A junction box (not provided) is necessary in the
AHU or ductwork to make the connection between the field
-installed 48VDC power wiring and the factory
provided humidifier power cable.
The factory-provided 25 foot data communication cable must be installed with the moisture-proof RJ45
connector at the humidifier and the standard RJ45 connector at the control box.
The factory provided end-of-line termination resistor must be installed in the second RJ45 port of the
humidifier.
Multiple Humidifiers (Grouped)
Once the humidifiers and control box are installed, the total 48VDC wire length and wire size (AWG)
should be determined for each
humidifier using the table on the preceding page.
A junction box (not provided) is necessary in the AHU or ductwork to make the connection between the
field
-
installed 48VDC power wiring and the factory provided humidifier power cable.
The factory provided 25 foot data communication cable must be installed with the moisture-proof RJ45
connector at the humidifier and the standard RJ45 connector at the control box.
Additional factory provided 20-foot RJ45 cable(s) with moisture-proof connectors at both ends must be
used to make the data communications connections between humidifiers within the
humidifier or
ductwork.
The factory provided end-of-line termination resistor must be installed in the second RJ45 port of the last
Ultrasonic Humidifier.
Multiple Humidifiers/Optional Multi-Tier Mounting Rack (Grouped)
Once the humidifiers and control box are installed, the total 48VDC wire length and wire size (AWG)
should be determined for each humidifier using the table on the preceding page.
A junction bo
x (not provided) is necessary in the AHU or ductwork to make the connection between the
field
-
installed 48VDC power wiring and the factory provided humidifier power cable. One junction box per
rack is typical.
The factory-provided 25-foot data communication cable must be installed with the moisture-proof RJ45
connector at the humidifier and the standard RJ45 connector at the control box.
Additional RJ45 cables with moisture-proof connectors at both ends will be factory installed to complete
the data communicat
ions connections between all humidifiers on
a single rack. Factory provided 20-foot
RJ45 cables with moisture-proof connectors at both ends must be used to make the data
communications connections between multiple racks within
the AHU or
ductwork.
The factory-provided end-of-line termination resistor must be installed in the second RJ45 port of the last
humidifier.
