Connectors and cables are shown in Fig. 3, Fig. 4, and Fig. 5.
Fig. 3 shows the viewing head cable with the 1/2 in. NPT pipe
fitting and pigtail for use in a conduit. The PF model comes
with 10 feet of Honeywell C330S cable. This cable is
recommended for all new installations. It has ITC and CIC
ratings for hazardous location. Figs. 4 and 5 describe the
C330S cable used with the right angle field-wireable
connector. Refer to "Accessories" on page 11 for part

The S70x/S80x viewing heads must be installed with a
connector and cable assembly that maintains the ingress
protection at the S70x/S80x viewing head. Additionally, ITC/
CIC approved cable installed in cable tray, or ITC/CIC
approved cable in metal conduit must be used between the
S70x/S80x and Signal Processor. Pre-assembled connector/
cable assemblies are listed below that provide the proper seal
at the viewing head, and meet ITC/CIC approvals. A field wire-
able connector that provides a proper seal at the viewing
head, along with ITC/CIC rated raw cable are also available
and listed below. The cable installation must conform to the
latest version of the National Electric Code, or Canadian
Electrical Code for Class I, Division 2 hazardous locations.
Additionally, the connector must be secured as follows: hand-
tighten the connector at viewing head, until it can no longer be
turned. Continue tightening the connector an additional 180
degrees using pliers, or similar tool.
WARNING
Over-tightening the connector can damage the
connector or housing.
Damage will void warranty and hazardous location
approvals. Do not exceed 180 degrees of further
rotation after hand tightening!
Verify that connector cannot be loosened by hand. This is
required for hazardous location installations.
