2.2 Choosing an installation site
All environmental and installation factors should have
been discussed with a Panametrics applications engineer
or field sales person at the time the XDP was ordered. Thus,
the equipment should be suited to the application and the
planned installation site. However, before installing the unit,
read these guidelines to verify that the best installation
site has been chosen for optimum instrument accuracy
and reliability.
• Make sure that the XDP and transmitter enclosures
are suitable for the environmental conditions at the
installation site.
• Install the system in a location with little or no vibration.
• Mount the transmitter in accordance with the instructions
provided in its accompanying documentation.
• Make sure the ambient temperature at the XDP installation
site is –10° to 60°C (14° to 140°F).
• Use a suitable electrical conduit to interconnect the
remote transmitter and the XDP enclosure.
• Use a suitable sample system between the gas source
and the sample inlet of the transmitter.
• Observe all normal safety precautions. Specifically, do not
exceed the maximum pressure and temperature ratings
of the transmitter or the sample system.
• Install the XDP system in a location that provides ready
access for programming, testing, and servicing the unit.
• Protect all cables from excessive physical strain (bending,
pulling, twisting, etc.). Do not subject the cables to
temperatures above 65°C (149°F) or below –50°C (–58°F).
• Be sure that the line voltage at the planned installation
site is within the specified power input rating for the XDP
(100-240 VAC; 50/60 Hz; 40 W maximum).
2.3 Mounting the XDP system
This section explains how to mount the XDP system
components and the transmitter/sample system at the
installation site.
WARNING!
The XDP requires an external power
disconnect device such as a switch or
circuit breaker. The disconnect device must
be marked as such, clearly visible, directly
accessible, and located within 1.8 m (6 ft)
of the unit.
HIGH VOLTAGE!
This symbol indicates the presence of
high voltage, which presents a potential
shock hazard for personnel operating
the equipment. Read and follow these
instructions carefully.
2.3.1 Mounting the XDP enclosure
Refer to "Figure 2" on page 8 , through "Figure 7" on
page 13 , and complete the following steps to mount
the XDP enclosure:
1. Select a flat surface on a vertical wall or instrument
panel with sufficient space to hold the XDP enclosure.
2. Locate and prepare four (4) mounting holes or two (2)
horizontal mounting rails on the vertical surface.
3. Secure the XDP enclosure to the mounting surface
with four (4) sets of mounting hardware. Be sure that
the enclosure is in a vertical position, with the display
window upright.
2.3.2 Mounting the remote
transmitter/sample system
Mount the remote transmitter in accordance with the
instructions in its accompanying documentation.
NOTE: Most Panametrics transmitters may be located
up to 2800 ft (850 m) from the XDP enclosure.
To provide reliable and accurate results, the transmitter
is often installed in a suitable sample system. The sample
system must deliver a clean, representative gas sample
to the inlet of the transmitter at the proper temperature,
pressure and flow rate.
NOTE: A suitable sample system may be ordered directly
from Panametrics. The sample system would be supplied
fully assembled on a flat plate with four (4) mounting holes.
See the sample system and/or transmitter manual for
more details.
