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
numbers.

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.
