INSTALLATION
SECTION 2.0
INSTALLATION
2.1 GENERAL. This analyzer's enclosure is suitable
for outdoor use. However it should be located in an
area where temperature extremes and vibrations are
minimized or absent. Installation must be performed
by a trained technician.
2.2 UNPACKING AND INSPECTION. Inspect the
analyzer for shipping damage. If damaged, notify the
carrier immediately. Confirm that all items shown on
the packing list are present. Notify Rosemount
Analytical if items are missing.
2.3 MECHANICAL INSTALLATION. Select an instal-
lation site that is at least one foot from any high volt-
age conduit, has easy access for operating
personnel, and is not in direct sunlight. Mount the
Model 1054B as follows:
1. Remove the four screws that secure the rear
cover of the enclosure (not required for wall
mounting, options 20 or 21). The latching hard-
ware for panel and pipe mounting is located
inside the rear cover.
2. For standard panel and pipe mounting, remove
the four screws holding the front panel assembly
of the enclosure and carefully pull the front panel
and connected printed circuit boards straight out.
3. Follow the procedure for the appropriate mount-
ing configuration: Section 2.3.1 for panel mount-
ing, Section 2.3.2 for wall mounting, or Section
2.3.3 for pipe mounting.
2.3.1 Panel Mounting (Standard). The Model 1054B
is designed to fit into a DIN standard 137.9 mm X
137.9 mm (5.43 in. X 5.43 in.) panel cutout (refer to
Figure 2-1 and Figure 2-2).
1. Prepare the analyzer as described in Section 2.3.
2. Install the mounting latches as shown in
Figure 2-2 (latches are shown oversize for clar-
ity). If the latches are not installed exactly as
shown, they will not work correctly. The
screws provided are self-tapping. Tap the
screw the full depth of the mounting latch
(refer to side view) leaving a gap greater than
the thickness of the cutout panel.
3. Align the latches as shown and insert the analyz-
er enclosure through the front of the panel
cutout. Tighten the screws for a firm fit. To avoid
damaging the mounting latches, do not use
excessive force.
4. Replace the front panel assembly. Circuit boards
must align with the slots on the inside of the enclo-
sure. Replace the door and four front panel screws.
2.3.2 Wall Mounting (P/N 23054-01). Refer to
Figure 2-3 and Figure 2-4. The integral preamp
(PN 23363-00) should not be used with this option.
1. Prepare the analyzer as described in Section 2.3.
2. Mount the junction box and bracket to the ana-
lyzer with the hardware provided. All wiring can
be brought to the terminal strip prior to mounting
the analyzer.
3. Place the metal stiffener on the inside of the ana-
lyzer and mount the two ¼-inch conduit fittings
using two each weather seals as shown. Mount
NEMA 4X conduit plug (included) into center con-
duit hole.
4. Mount the analyzer to the junction box using the
1/2-inch conduit fittings.
5. Complete wiring from the 1054B to the junction
box (Figure 2-4).
2.3.3 Pipe Mounting (P/N 23053-00). The 2-inch
pipe mounting bracket includes a metal plate with a
cutout for the 1054B refer to Section 2.3 for mounting
the analyzer into the plate. Mounting details are
shown in Figure 2-5.
2.3.4 Wall Mounting Enclosure (Option -20). Refer
to Figure 2-8. In this configuration, the analyzer is
housed in NEMA 4X heavy duty enclosure and may
be mounted on a wall or handrail. Sufficient clearance
should be provided in front of the enclosure to permit
opening the door, which is hinged on the left side.
