1.3 MOUNTING OPTIONS
1.3.1 Analyzer Dimensions
• Figure 1-1 calls out the analyzer dimensions with
the lid closed.
• Figure 1-2 shows the depth dimensions of the ana-
lyzer. When wall or panel mounting, make sure to
allow adequate space for opening the enclosure
door or making electrical connections.
DANGER
Only properly trained and qualified personnel
should install the RDO analyzer described in this
manual. This instrument should be installed for use
in nonhazardous locations only.
L'installation de l'appareil "RDO" décrite dans le

1.3.2 Pipe Mounting
1. Remove the four nuts and four screws from the
mounting kit.
2. Open the enclosure and drop one nut into each
drilled corner of the box (Figure 1-3).
3. Use a screwdriver to push the nut down and set it in
place (Figure 1-3).
4. Orient the two brackets on the back of the enclosure
so that the flanges on the brackets point downward
(Figure 1-4).
5. Attach the mounting brackets to the enclosure using
two screws for each bracket. Make sure that the
screws properly thread into the nuts you seated in
steps 2 and 3.
6. Place two hose clamps over the mounting pipe and
tighten them until they almost secure.
7. Place the flanges from the mounting bracket into
each of the hose clamps (Figure 1-3).
8. Tighten the hose clamps until the analyzer is secure
on the pipe.

1.3.3 Wall Mounting Using Mounting Tabs
The optional mounting kit contains a set of wall mount-
ing hardware that includes four screws, nuts, and tabs
for mounting the analyzer to a wall or panel. Follow the
instructions included with the mounting tab hardware to
attach the tabs (Figure 1-6).
1.3.4 Wall Mounting with User-supplied Screws and
Hardware
You can supply your own mounting hardware and
attach the analyzer to a wall. Figure 1-3 indicates the
placement of the nut. Use a screw that is best suited for
your wall material (Figure 1-7).
1.3.5 DIN Rail Mounting the Enclosure
1. Open the enclosure and drop one #6 screw into
each drilled corner of the box (Figure 1-8).
2. Use a long screwdriver to push the screw through
the back of the enclosure (Figure 1-8).
3. Place the DIN clip on the top of the enclosure with
the orientation shown in Figure 1-9.
4. Use a long screwdriver to tighten the screw to the
clip.
5. Repeat steps 2-4 for the remaining screw and clip.
6. Mount on a DIN rail.

1.4 INSTALLING DOME CONNECTORS
AND PLUGS
Install dome connectors and plugs as shown in Figure
1-10.
1. Place the O-ring over the threaded end of the con-
nector or plug.
2. Screw the connector or plug into the opening until it
is snug. Then tighten an additional 1/2 turn. Do not
overtighten.
3. Place the lock nut concave side down on the
threads and using a screwdriver blade and mallet,
tighten the lock nut until there is approximately one
thread showing.
4. Thread cable through the dome connectors and
secure by tightening the nut to about 15 in-lbs of
torque. Confirm that cable does not slide or wiggle
after the nut has been tightened. Leave sufficient
cable inside the enclosure to make secure connec-
tions without placing stress on the cable.

MODEL RDO WIRING
2.1 ELECTROSTATIC DISCHARGE (ESD)
RECOMMENDATIONS
• Before making wiring connections or
touching circuit boards or other internal
components, discharge any static elec-
tricity from your body by touching a grounded metal
object.
• When making wiring connections, make sure to
remain properly grounded by wearing an ESD wrist
strap or similar device.
2.2 CUSTOMER-SUPPLIED ELECTRICAL
EQUIPMENT
The user must supply the following:
• 18-12 AWG wire for electrical connections using
conduit or 100-240 VAC power supply
• 24-12 AWG cable for connecting relays and PLC
devices
• A 100-240 VAC or 9-36 VDC source with over cur-
rent/disconnect protection for hard-wired locations
using conduit.
• Approved suitable wiring for cord-connected plug
and socket locations.
SECTION 2.0
WIRING
DANGER
Only properly trained and qualified personnel
should install the RDO analyzer described in this
manual. This instrument should be installed for use
in nonhazardous locations only.
DANGER
2.3 ENSURING GOOD ELECTRICAL
CONNECTIONS
To ensure that all sensors and power sources function
properly, make sure that:
• Each individual wire is stripped and tinned to ¼ in.
• Each wire is tightly screwed into the terminal strip.
• Each wire is touching the terminal strip. If the plas-
tic wire jacket is clamped into the terminal strip, con-
nections will not be made.
• Clip or cap any unused wires.
DANGER
Make sure that power to the instrument is discon-
nected before making any wiring connections.
DANGER
Débrancher toute alimentation à l'appareil avant de
connecter les fils.
DANGER
Do not connect low voltage circuits (<50 V) to the
terminal connectors on the AC board!
DANGER
Ne pas connecter des circuits basse tension
(moins de 50 V) aux bornes de connexion sur la
carte électronique de secteur (courant alternatif)!

FIGURE 2-1. AC circuit board
and terminal connections
The AC power board is located under the metal shield on
the right side of the enclosure. The terminal strip on the
board accommodates the AC power connections as well
as two high voltage relay connections. See Figure 2-1.
1. Remove the front cover of the enclosure.
2. Remove the metal AC power board cover.
3. Thread the power cable and relay wires (if needed)
through the dome fittings nearest the power board.
4. Using the green screw, connect the green earth wire
of the power cable to the metal frame in the bottom
of the enclosure. See Figure 2-2. A green wire con-
necting the metal frame to the terminal strip should
already be in place.
