2-2 Installation
Choosing an Installation
Site
All environmental and installation factors should have been discussed
with a GE Sensing 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 used at the planned installation site
corresponds to the factory preset line voltage rating for the XDP.
