6.3: Mounting the Optional Nexus
The Nexus® 1262/1272 meter has its own LCD Display on the meter face. The optional Nexus®
LED Displays: P40N, P41N and P43N, may be used where additional displays are desired. The
display mounts using a standard ANSI C39.1 drill plan. Secure the four mounting studs to the back
of the panel with the supplied hardware. See Chapter 9 for details on External Displays.
Six feet of RS485 communication/power cable harness is supplied. Allow for at least a 1.25-inch
(3.17cm) diameter hole in the mounting panel for the cable harness.
The display is powered by an external power source, such as the PSIO, which supplies 12 VDC.
Each display requires 3 VA (typical). The P40N can draw up to 500 mA in display test mode.
See Figure 5.9 for wiring detail (wiring is the same as for the P60N display and Output Modules).
