2-56 Installation
To wire the multicolored ribbon cable to the extra connector and make connections at the
WPC 1000 Control and Display boards, do the following:
1.
Run the end of the cable lacking a connector through flexible, liquid-tight conduit and
through a knockout or other opening in the enclosure or console to the mounting location
for the WPC 1000 display. Because WPC 1000 is rated NEMA 12 (protected against dust
and oil), you must use conduit of the same rating and make proper connections to ensure
NEMA 12 protection.
2.
Leave enough cable inside the WPC 1000 enclosure to reach the 34-pin connector J104 on
the WPC 1000 Control board (see Figure 2-11, page 2-20) and to allow for a service loop.
Also, make sure that there is enough cable at the Display board end to reach J706,
measuring from the last pair of gray stripes on the cable (see step 4).
3.
Plug the already installed ribbon cable connector into J104.
4.
At the Display board end of the ribbon cable connection, look for the two parallel gray
stripes stamped on the cable jacket every 18 in. (see Figure 2-32). These marks occur
roughly at the midpoint of 3-inch-long sections of cable where the conductors are
flattened for easy attachment to the connector. Conductors in all other areas of the cable
are twisted and cannot be attached to the connector.
5.
Determine the striped marking that allows you enough cable to make a comfortable
connection at J706 on the WPC 1000 Display board, then cut the cable about 1 in. away
from this marking on the free end of the cable (see Figure 2-32).
6.
Strip the black outer jacket from the end of the cable to expose about 4 in. of wiring, being
careful not to cut through the insulation around the conductors.
7.
Spread the ribbon cable conductors apart so they lie flat, as shown in Figure 2-33,
page 2-57. Note that one edge of the exposed cable has a brown wire, the other edge a tan
wire.
The ribbon cable connector can be plugged into the J104 connector in only one direction.
When inserting the plug, make sure to align the key in the plug (see Figure 2-31) with the
middle groove on the J104 connector. If the plug is not inserted correctly, the display will
not work properly.
