2. Insert each wire into the appropriate opening on the connector according to
the wiring diagrams and connector types described in this section.
3. Turn the flat-blade screws clockwise to secure the wire in the connector.
Wiring guidelines
Touch Panels require regulated 12 VDC power to operate properly. The AXCESS
Central Controller supplies power via the AXlink cable. The maximum wiring
distance between the control system and Touch Panel is determined by power
consumption, supplied voltage, and the wire gauge used for the cable. Figure 13
lists wire sizes and the maximum lengths allowable between the Touch Panel and
control system. The maximum wiring lengths for using AXlink power are based on
a minimum of 13.5 volts available at the control system’s power supply.
Wiring guidelines for Touch Panel (800 mA)
Wire size Maximum wiring length
18 AWG 146.71 feet (44.71 m)
20 AWG 92.8 feet (28.29 m)
22 AWG 57.9 feet (17.65 m)
24 AWG 34.5 feet (10.52 m)
If you install the Touch Panel farther away from the control system than
recommended in Figure 13, connect an external 12 VDC power supply as shown in
the wiring diagrams in this section.
Caution
Do not over-torque the
screw. Doing so can bend
