Note: When the older generations of 65UV5-1000 or -1000E scanners are used for a Class 1, Div. 2
application, the cable gland MUST be removed and replaced with P/N 129-149, liquid tight cable
gland, so that liquid tight flexible conduit (Anaconda Sealtight ® 1/2" Type H.T.V.A or equivalent,
available at any electrical supply outlet) can be inserted over the existing cable. The newer genera-
tion 65UV5-1004 and 1004E utilize a special cable that is approved for use in a Class 1, Div. 2 area
without the use of the flexible conduit.
SCANNER WIRING - CEX VERSIONS
CEX models contain two internal four-pole terminal blocks for the user to connect their scanner
cable. The terminal blocks are identified by the internal wire color code and functions as described in
Table 2 and Figure 9 below.
The installer must use a suitable EX cable gland or conduit fitting at the CEX housing's ¾" NPT
threaded cable entry opening.
To reduce electrical noise interference, take precautions to keep the scanner cable away from any
high inductive wiring associated with high inductive loads or high voltage, high energy spark igni-
tion systems.
