Chapter 2. Installation
2.2 Wiring the oxy.IQ
To wire the oxy.IQ, refer to Figure 14 on page 28 , then proceed as follows:
1. Attach the appropriate cable to the oxy.IQ (see Figure 5 below). Be sure to align the white arrow on the cable
connector with the white arrow on the oxy.IQ connector, and then push the top of the cable connector straight
down onto the mating connector on the rear of the electronics module until you hear it click into place.
IMPORTANT: Do not rotate the cable connector during installation (it is not threaded) and do not hold the connector
by its bottom section while pushing it down into place.

2. Connect the flying lead end of the cable as shown in the wiring diagram, according to one of the following
conditions:
• No Zener barrier or galvanic isolator: For use in non-hazardous areas or div 2 hazardous areas.
• With Zener barrier or galvanic isolator: Required for use in hazardous areas.
IMPORTANT: To remove the cable from the oxy.IQ electronics module, simply pull straight up on the lower section of
the cable connector as close to the oxy.IQ body as possible. Do not pull on the cable or the upper portion
of the cable connector, and do not try to unscrew the cable connector.
2.2.1 Longer Cable Lengths
Panametrics offers cables in 2 m and 10 m standard lengths. Longer cable lengths may be used with the oxy.IQ, but
these are not available from Panametrics. If you require a longer cable, refer to the following figures for the required
cable specifications and construct your own cable for splicing onto the standard Panametrics cable:
• Standard cable: figure 10 and figure 11.
• IS cable: figure 12 and figure 13.
WARNING!
For IS (Intrinsically Safe) applications, the oxy.IQ must be installed with a zener barrier
(see the top of Figure 14 on page 28 ). Also, for installations in a hazardous location, the
blue IS cable (p/n 704-1318-02, 10) must be used.
