4. Pull ground, neutral and hot wires (#14 AWG minimum) into the
power terminal box inside the heated enclosure.
5. Strip back the jacket and/or insulation of the wires just enough to
connect to the power terminal block.
6. Attach the neutral and hot wires to the power terminal by connecting
the neutral wire to the terminal marked “N” or “NEU,” the hot wire
to the terminal marked “H” or “LINE,” as shown in Figure 3–1 on
page 3–4.
7. Connect the ground wire to the ground terminal marked “G” or .
8. Close the power terminal box.
9. Close and latch the heated enclosure door.
Checking the SCS Installation
The integral SCS is factory set with the appropriate pressures, flow rates and
enclosure temperature as indicated in the system drawings for your analyzer.
However, before operating the system for the first time, a careful check of the
installation of the entire SCS from the sample probe to the flare/vent is
recommended. SpectraSensors also recommends purging the sample transport
line to confirm there is no dust, particulates or liquids that were trapped during
installation.
To perform SCS installation checks
1. If a sample probe is used with the system, confirm that the sample
probe is correctly installed at the process supply tap and that the
sample probe isolation valve is closed.
2. If a field pressure reducing station is used with the analyzer, confirm
that the field pressure reducing station is installed properly at the
sample probe.
3. Confirm that the relief valve vent line is properly installed from the
field pressure reducing station or the SCS to the low pressure flare
or atmospheric connection.
4. If applicable, confirm that the sample probe and field pressure
reducing station are properly traced and insulated without any
exposed surfaces.
5. Confirm that the field run electric-traced sample transport tubing is
installed correctly (no exposed tubing or pockets), terminated
An optional sample probe and/or field pressure reducing station
may be provided by SpectraSensors or through a third party.
