Figure 2-15: Rear of Display with Long Nuts Installed
Remove the short harness wires from the back of the display assembly by pressing the small
orange lever beside each terminal (Figure 2-16) and pulling the wire out. The harness should be
completely removed from the display. Remove the four-position terminal block from the other end of
the harness.
Figure 2-16: Orange Levers on Display Board Connector
Install the four-position terminal block on one end of the new, longer, length of cable, and connect
the other end to the display board connector, as indicated in Table 2-1. The cable used should be a
shielded, four conductor cable in which each conductor is a minimum of 0.3 mm2 (22 GA). The
maximum cable length for remote mounting is 15m (50 ft). To prevent electrical interference on
cables more than 2m (6 ft) long, the shield should be grounded to one of the studs on the back of
the operator interface.
The display can be connected either to J5 on the rear of the DIN housing or to COM1 (if
programmed for Front Panel assignment). The wiring is the same for both connections as shown in
Table 2-1.
