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 gray cable is
labeled: LAPP USA UNITRONIC 190CY B (UL) TYPE CMG
105C 22AWG/4C SHIELDED E130334 – CSA CMG 105C or
AWM II A/B 300V LL74246. The standard pigtail length is 10
feet (3.0m). The S706PF-050 has a 50-ft (15 m) pigtail length.
This cable must be used with a conduit in hazardous
locations. It can also be ordered commercially as Olflex
602204S.
The recommended cable for hazardous locations, C330, is
shown in Fig. 4 with the right-angle connector and Fig. 5. It is
supplied as standard in a 15 ft. (4.6m) length with other
available lengths. This cable does not have to be used in a
conduit. It is labeled: C-330E193849 (UL) TYPE ITC 4/C 18

Fig. 3. Model 700 Viewing Head Cable With 1/2 in. NPT Fitting.
AWG 90C 300V OR c(UL) CIC 90C 600V FT4 SUNLIGHT
RESISTANT. C330 cable with or without the connector wired
at the factory can be purchased from Honeywell. Refer to
"Accessories" on page 10 for part numbers.
The customer may also supply his own cable; a replacement
mating viewing head connector should be ordered. Refer to
"Accessories" on page 10 for part numbers. The use of
shielded cable is recommended, either an overall shield or a
cable with a shield for the signal line. The shield should be
connected to GND at the processor end and to the ground
wire at the viewing head end. The cable diameter should not
exceed 0.307" in order for it to go through the hex bushing in
the connector. But note that wiring the cable to the connector
is not easy because of the limited space. Also, the LED
indicator assembly must be mounted inside the connector
and, preferably, soldered in place. Thus, it is recommended to
purchase a pre-wired cable and connector assembly from
Honeywell.
NOTE: FOR CLASS I, DIV 2 RATING, CABLING IN
HAZARDOUS LOCATIONS MUST COMPLY WITH
NEC ARTICLE 500 REQUIREMENTS AND
APPLICABLE GOVERNING CODES.
In the U.S., cables should have UL's ITC rating; in Canada,
cables should have CSA's CIC rating. The recommended
C330 cable has both ratings.
NOTE: To obtain a NEMA 4X seal between the connector
and the viewing head, tighten the metal
connector ring securely.
