Wiring for all Models
Install wiring in accordance with the electrical code of the country in use
and UL 61010-A1 or CSA C22.2 No. 1010.1, as applicable. In these
installations, twisted-pair, instrument quality cable is recommended.
Shielded cable is recommended for cable runs where interferences from
radio frequency interference (RFI), electromagnetic interference (EMI)
or other noise sources exist (such as motors, welding equipment,
heaters, etc.).
NOTE: See Installation Outline Drawings for wiring details as specified
in TABLE 1-1.

Conduit may also be needed in areas where large amounts of electrical
noise is expected.
Use caution when selecting a cable size. TABLE 1-2 expresses the
maximum cable length when only using the Ultima X Series Gas
Monitors. Ultima X Series options may take additional power which
requires a heavier cable or a short cable run. Cable distances for units
with internal relays are specified in Appendix A, TABLE A-1.
When selecting cable size, consider future needs (i.e., addition of
sensors and/or options available with the Ultima X Series Gas
Monitors). See Chapter 3, TABLE 3-1, "Performance Specifications"
for proper input voltage.
Ensure that water and dirt are not able to enter the unit via the wire or
conduit. If the unit is installed in a location known to be wet or damp, it
is good practice to loop or bend the entry into the unit that prevents
water incursion.
All cable shields should be terminated to earth ground at one end only.
