Mounting the XDP 
System
This section explains how to mount the XDP system components and 
the transmitter/sample system at the installation site.
IMPORTANT: 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.
IMPORTANT: This symbol indicates Caution - risk of electric 
shock:
Mounting the XDP 
Enclosure
Refer to Figure 2-1 on page 2-9, 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. Using the mounting dimensions shown in Figure 2-1 on page 2-9, 
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 at the top.
Mounting the Remote 
Transmitter/Sample 
System
Mount the remote transmitter in accordance with the instructions in 
its accompanying documentation.
Note: Most GE Sensing transmitters may be located up to
2,800 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 is designed 
to 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 GE 
Sensing. The sample system would be supplied fully assembled 
on a flat plate with four (4) mounting holes. See the sample 
system and/or transmitter manuals for more details.
